How To Troubleshoot Vehicle Ride Comfort By Addressing Bumpy Ride and Handling

November 3, 2023 by Denver Express Car Care

Do you ever feel like your car is taking you on an unexpected off-road adventure even when you’re driving on a perfectly smooth highway? That jarring experience of a bumpy ride can be frustrating and uncomfortable. Thankfully, there are ways to troubleshoot and improve your vehicle’s ride comfort, ensuring your journeys are as smooth as possible.

Consider Your Recent Drives – Has Something Recently Happened?

Where have your travels recently taken you? Did you hit a curb in the parking lot? Hit a pothole on the highway?

Taking a step back and reflecting on your recent driving experiences can reveal a lot. Has your car’s ride comfort deteriorated suddenly, or has it been a gradual process? Understanding the context can help you pinpoint the root cause of the bumpy ride.

What Makes a Car Ride Comfortable?

What makes a ride comfortable in the first place?

When most people think about comfort, they immediately go to comfortable seats, an aesthetically pleasing interior, or comfort controls to keep you warm or cool. But there are other factors that play into comfort.

Ride quality also matters. Have you ever thought your sedan feels like a pickup truck? That decreases the experience of the ride. That also points to a problem with one or more systems within your vehicle.

How To Troubleshoot Vehicle Ride Comfort By Addressing Bumpy Ride and Handling

If your car feels bumpy out on a smooth road, there are several possible reasons why it’s occurring. This is the time for an inspection, to alert you to problems that can grow more serious with time.

Some Things That Might Cause a Bumpy Ride

What are some of the common culprits that can turn your smooth ride into a bumpy one:

Uneven Tire Wear – Tires with uneven wear patterns can result in vibrations and a bumpy ride. Regularly inspect your tires for signs of wear and replace them when necessary.

Bad Alignment – Improper wheel alignment can lead to uneven tire wear, pulling to one side, and a bumpy ride. If you notice your car drifting to the left or right, it might be time for a wheel alignment.

Tire Pressure – Incorrect tire pressure can affect ride comfort. Overinflated or underinflated tires may lead to a harsh or bouncy ride. Always check and maintain the recommended tire pressure.

Damaged Suspension – A damaged or worn-out suspension system can no longer effectively absorb shocks from the road, resulting in a rough ride. Signs of suspension issues include excessive bouncing, nose-diving when braking, or a sagging back end.

Damaged Transmission – Transmission problems can manifest as jerky or erratic movements when driving. This not only affects ride comfort but can also indicate severe mechanical issues that need immediate attention.

Braking System – Worn-out brake components, such as brake pads and rotors, can cause vibrations and uneven braking, making your ride less comfortable and unsafe.

Excessive Weight – Overloading your vehicle with excessive weight can put added stress on the suspension and tires, leading to a bumpy ride. Be mindful of your vehicle’s weight limits and distribute the load evenly.

How to Make a Ride Smoother

Regular inspections and maintenance are among the easiest ways to troubleshoot a bumpy ride. When you bring your car in regularly for inspections, it will alert you to potential issues before they grow. You can fix minor problems before they escalate.

What does that look like?

Regular Tire Maintenance – Start by checking your tire pressure regularly, ensuring it matches the manufacturer’s recommendations. Inspect your tires for signs of uneven wear, and if necessary, rotate them to promote even wear patterns. Replace worn-out tires promptly.

Wheel Alignment – If you notice your car pulling to one side or uneven tire wear, schedule a wheel alignment with a reputable auto shop. Proper alignment ensures that your tires make optimal contact with the road, improving ride comfort and handling.

Suspension Inspection and Repairs – If you suspect suspension issues, have your vehicle’s suspension system inspected by a professional mechanic. They can identify worn-out components and replace them as needed to restore ride comfort.

Transmission Service – If your car exhibits jerky movements or struggles to shift gears smoothly, consult a qualified mechanic for a transmission service. Addressing transmission problems can significantly improve ride quality.

Brake Maintenance – Regularly inspect and maintain your vehicle’s braking system. Replace worn brake pads, rotors, and other components as necessary to ensure smooth and effective braking.

Weight Management – Avoid overloading your vehicle with excessive weight. Follow the manufacturer’s weight limits, and distribute the load evenly to prevent stress on the suspension and tires.

Consider Aftermarket Suspension Upgrades – Depending on your vehicle and your preferences, you might explore aftermarket suspension upgrades. These can include shock absorbers, struts, and springs designed to enhance ride comfort and handling.

Drive Smoothly – Your driving habits can also affect ride comfort. Avoid sudden acceleration, hard braking, and sharp turns. Smooth, controlled driving can help minimize discomfort for you and your passengers.

Regular Maintenance – Finally, don’t underestimate the importance of routine vehicle maintenance. Following your manufacturer’s recommended maintenance schedule ensures that all systems are in optimal condition, contributing to a smoother ride.

A bumpy ride can be a frustrating and uncomfortable experience, but it’s not something you have to endure. Understanding the factors contributing to ride comfort can significantly improve your vehicle’s ride quality. Regular maintenance, responsible driving habits, and occasional upgrades can all play a role in making your journeys smoother and more enjoyable.

If you’re having trouble figuring out what’s causing your bumpy ride, don’t ignore it. It’s best to take your vehicle to a mechanic as soon as possible. They’ll be able to tell you for sure where the problem is and how to fix it.

When was the last time you experienced a bumpy ride?

Diagnosing and Resolving Steering Vibrations

October 21, 2023 by Denver Express Car Care

Driving is something we take for granted. We slide behind the wheel, and head out into our days.

Until something goes wrong.

Some things start slowly, building up over time. Other things spring into the moment – you can’t help but notice there’s a problem with your vehicle.

If you have a steering vibration, you’ll notice it quickly. It can be an unnerving sensation when your steering wheel shakes and vibrates. It can also be dangerous.

Why is your steering wheel shaking? What can you do about it? Let’s explore.

How Steering Works

At its core, your vehicle’s steering system is responsible for directing the movement of your car. It allows you to control the direction of your vehicle, whether you’re navigating a tight parking space or cruising down the highway.

Most modern cars utilize a rack-and-pinion steering system. When you turn your steering wheel, it’s connected to a steering column, which, in turn, connects to a rack-and-pinion gear set. As you turn the wheel, it moves the rack left or right. This motion is then translated into the movement of your vehicle’s front wheels, causing them to turn and steer the car.

Diagnosing and Resolving Steering Vibrations

Why Does My Steering Wheel Shake?

Steering wheel vibrations are a common issue and can stem from various sources. These vibrations are not something to be ignored, as they can indicate underlying problems with your vehicle’s safety and performance.

Steering Vibrations at Low Speeds

When you experience steering vibrations at low speeds, particularly while idling or moving slowly, it could be due to issues with your vehicle’s engine or transmission mounts. These mounts are responsible for stabilizing the engine and transmission and can wear out over time, causing vibrations that are transmitted to the steering wheel.

Steering Vibrations While Braking

Steering vibrations during braking are a clear indication that your brake system needs attention. This could be due to warped brake rotors, uneven brake pad wear, or problems with your brake calipers. When you apply the brakes, these issues can lead to uneven braking, resulting in steering wheel vibrations.

Steering Vibrations While Accelerating

If your steering wheel shakes while accelerating, it might be related to problems with your vehicle’s driveline components. Issues with the driveshaft, universal joints, or CV joints can cause vibrations to transfer to the steering system. These vibrations are often more noticeable during acceleration because of the increased load on these components.

Steering Vibrations While Driving at High Speeds

High-speed steering vibrations can be unsettling and potentially dangerous. They are often caused by imbalanced wheels or tires. When your wheels are not properly balanced, they can create uneven vibrations, which become more pronounced at higher speeds. This can result in a shaky steering wheel and compromised handling.

Steering Vibrations While Turning

Vibrations while turning could be related to problems with your vehicle’s suspension components. Worn-out or damaged control arms, bushings, or struts can lead to instability in the steering system, causing vibrations when you turn the wheel. This can affect your ability to maintain control while cornering.

Why Wheel Balancing Is Important

Wheel imbalance is a common factor in steering vibrations, especially at high speeds. Wheel balancing is a crucial maintenance task that ensures the weight distribution on each wheel is even. Even minor weight discrepancies can result in noticeable vibrations when wheels are not balanced.

During wheel balancing, a technician will use specialized equipment to measure the imbalance and add or remove weights as needed to achieve an even distribution. This process not only eliminates steering vibrations but also improves tire longevity and enhances overall ride comfort.

Regular wheel balancing should be part of your vehicle’s maintenance routine to prevent steering vibrations and ensure a smooth, safe ride. For optimal results and a smooth ride, it’s advisable to balance all four wheels and tires, even if only one is causing vibrations. Balancing all wheels helps maintain consistency and ensures the vehicle’s handling remains balanced.

Schedule a Steering Inspection Today

If you’ve been experiencing steering wheel vibrations, it’s essential to address the issue promptly to ensure your safety and the longevity of your vehicle. Ignoring these vibrations can lead to more severe problems down the road.

To diagnose and resolve steering vibrations, it’s advisable to schedule a steering inspection with a qualified automotive technician. During the inspection, they will thoroughly examine your vehicle’s steering and suspension components, as well as perform a wheel balancing check.

Steering inspection is essential for:

Safety – Vibrations in the steering wheel can affect your ability to control the vehicle, especially during critical maneuvers. Resolving these issues promptly ensures your safety on the road.

Prevent Further Damage – Steering vibrations can be symptomatic of more significant underlying problems. By addressing the issue early, you can prevent further damage to your vehicle’s components.

Improved Comfort – A smooth, vibration-free ride is safer and more comfortable. Eliminating steering vibrations enhances your overall driving experience.

Longevity – Regular inspections and maintenance can prolong the lifespan of your vehicle and its components, saving you money in the long run.

Enhanced Fuel Efficiency – When your wheels are not properly balanced, it can lead to extra resistance and friction on the road. This added resistance requires more energy, which, in turn, leads to increased fuel consumption. Maintaining balanced wheels can improve your vehicle’s fuel efficiency and save on gas expenses.

When scheduling a steering inspection, be sure to communicate your concerns and describe when you most frequently experience the vibrations. This information can help the technician pinpoint the issue more accurately.

While these vibrations can be unsettling, addressing them promptly through a steering inspection and necessary repairs is crucial for your safety and the performance of your vehicle.

If you’ve been noticing your steering wheel shaking, don’t hesitate – schedule a steering inspection today and get back on the road with confidence. Your vehicle and your peace of mind will thank you.

This Is How You Know If You Have Suspension Problems

December 24, 2022 by Denver Express Car Care

When you head out for a drive, you expect a smooth ride. When you hit a bump, you barely notice it, and continue along.

Unless your suspension has problems.

The suspension system includes shock absorbers, struts, springs, and tires. Each component works together to smooth out the bumps in the road. If one part is weak or failing, you’ll feel it.

How the suspension system works

Performance vehicles love to focus on power. Manufacturers will talk about torque, horsepower, and zero-to-sixty acceleration.

But performance doesn’t mean much if you can’t control the car. Without a suspension system, you’d never be able to handle those performance features. It’s required for both handling and comfort of the passengers.

If all roads were straight lines, flat with no bumps or curves, your vehicle wouldn’t need a suspension. That’s not the case. Driving is all about stopping and starting, merging into traffic, and turning to get to your destination. It’s a series of movements – some planned, some not – to get you to where you’re going.

The suspension system is built into the chassis, which includes all of the main parts of the car located beneath the body. It includes:

This Is How You Know If You Have Suspension Problems

The frame – the structural component of the car
The suspension – supports the weight and absorbs the shocks associated with driving
The steering – gives you full control over the vehicle’s direction
The wheels and tires – motion and grip of the road.

The major components also include:

Springs, which provide support and control the load and height of the suspension
Shocks, which absorb and dampen the energy from the tires as they connect to the road
Anti-sway bar, which shifts the movement of your wheels relative to the steering wheel

When you hit a bump in the road, it forces the wheel to move up and down relative to the energy within the bump. Smaller bumps will barely be noticeable. Larger bumps transfer a lot of energy. This energy is absorbed by the suspension system, which means none of the force makes it to the passenger compartment.

What happens when your suspension system has problems

If the suspension system works well, your car will handle well. As various components of the suspension system wear out, you’ll feel it in different ways.

Bouncing when you hit bumps in the road

Hitting potholes, slowing for speed bumps, navigating dips in the road – it’s all a part of your typical commute. If you start to feel each pothole, speed bump, or dip, it might be a sign of a suspension problem. This bouncing movement starts when your shocks are worn out. Shock absorbers are designed to help dampen the impact of movement in the suspension system, and help control the workload of the springs. When the shocks wear out, the springs are left to do all of the work. It’s this excessive spring action that creates the bounce.

Play in the steering wheel

The steering function is interrelated to the suspension system. If the suspension fails, the vehicle will be more likely to wander from side to side rather than continuing in a straight line. It’ll feel loose as you steer and keep it between the lines. This can also be caused by poor steering alignment, so it’s important to bring it in for inspection to determine where the problem originates from.

Dipping while braking

When you hit the brakes hard, you should feel every system respond and move into action. It’s a tight process that keeps you safe in emergency situations. If you have a problem with the suspension system, however, you may notice the front of the car dips down when you hard brake, the tightness loosens up a bit. This is a sign you need new shocks. It’s a sign they no longer are doing their job.

Vehicle leans when it’s parked

Have you ever performed a “flight check” before you drive your car? It’s a good idea to walk around it every once in a while to ensure all systems appear to be working well. This gives you a chance to look at the tires and notice anything that appears to be off. If you notice one corner leans down, lower than the other corners, it’s a sign of suspension failure. An easy way to notice a problem is to focus on the way the tires sit in the wheel well. The space between the tire and the bodywork should be the same on all four sides.

Pulling to one side

Have you noticed your car pulling to one side or the other while you drive? It’s a sign of a suspension problem. When you’re traveling down a straight road, it should take little effort for your car to stay moving forward. You’ll feel a pull if there’s a problem. It could be a tire that is softer than the other three; it’s pressurized differently. If you notice it more while driving around corners, it might be an alignment problem.

A noisy ride

Your car is designed to block out the noises of the road. When parts start wearing down and failing, they’ll create unique sounds. When you start to hear a repetitive squeaking or clunking noise coming from under the hood, it’s usually a sign of a suspension part failing. Like other components on your vehicle, the suspension will last anywhere from 50,000 to 100,000 miles. Check your owner’s manual for details on when you can expect to replace each part. If you’re nearing end-of-life for any major part, a proactive approach would be to replace it sooner rather than later. This ensures it never fails at an inopportune time.

Summary

A car’s suspension system is just one of many crucial components to give you a safe, comfortable ride. Without a suspension system, you’d face each bump with more force, and have more risk on your drive.

To ensure your suspension system is in good working condition, schedule an inspection with a certified mechanic at the first sign of trouble. It’ll protect you from further damage, and ensure a better drive.

How Worn Out Shocks and Struts Can Cause An Accident

April 14, 2022 by Denver Express Car Care

How long can you drive on worn out shocks and struts? It depends. Like other parts on your vehicle, they rarely fail overnight. Instead, it’s a process where they gradually wear down, causing more problems with your drive. Eventually, their failure can lead to an accident.

But before shocks and struts fail, they start giving warning signals. That’s where you should start paying attention. This gives you ample warning, and provides you with enough time to get them replaced.

How shocks and struts work

Shocks and struts work as stabilizers. Every turn you make, every time you accelerate or step on the brakes, the shocks and struts work to keep your vehicle under control. Without shocks and struts, you would feel every bump in the road.

Today’s vehicles use shocks, struts, or a combination of the two. Though the two are often used interchangeably, there is a difference. Shocks are individual components of the suspension system, while struts are a structural component.

A shock absorbers job is to control the spring and suspension movement by converting kinetic energy into heat energy, and dissipating it through hydraulic fluid. All modern day shock absorbers are velocity sensitive, which means with faster movement comes more resistance. That allows the shock absorber to adjust to the varying road conditions. This protects you from bouncing, swaying, or diving as you stop and go in traffic.

How Worn Out Shocks and Struts Can Cause An Accident

A strut is a structural part of the suspension, taking the place of the control arm and upper ball joint of the conventional system. It’s lighter and takes up less space than a shock absorber. Struts provide the same damping function as shock absorbers. But they also provide structural support for the vehicle’s suspension. It supports the spring, and keeps the tire in alignment. It also bears the side load placed on the suspension. While struts also provide comfort and handling, they also are designed for wheel alignment and prevent wear on other parts of the suspension system.

How shocks and struts can cause an accident

Shocks and struts gradually wear out over time. You’ll start noticing a difference in the way your vehicle handles as you drive. If they fail, it can lead to an accident as you:

Drive over bumps and dips

If your shocks and struts aren’t working, you lose your ability to navigate. Bumps and dips can cause vibration, which may cause you to lose control over your vehicle. Taking a speed bump too fast may make it feel like your car is “flying.”

Steer around curves and turns

If your vehicle isn’t properly gripping the road, it can cause you to over or understeer, putting you in a dangerous situation.

Lose control over your brakes

Your shocks and struts and anti-lock braking system work together to help you drive. If your shocks and struts aren’t working, that passes into your braking system. If you’re driving along on a bumpy road, for example, you may lose control over your steering, and not have the ability to brake for other objects in your path.

Cause other parts to wear down faster

Your vehicle consists of 10,000 working parts, all coming together to help you stay comfortable and safe while you drive. If one part wears down and fails, it impacts every other part of the system. Shocks and struts can affect a variety of parts, including tires, brakes, and more. Following a regular maintenance schedule is the easiest way to ensure every component is working well to help you drive safely down the road.

What are the warning signs of failing shocks and struts?

Luckily, shocks and struts don’t wear down without warning. If you notice any of these warning signs, schedule an appointment with a mechanic as soon as possible.

You feel a constant up and down movement as you drive, especially at higher speeds. The movement may be slight, but once you notice it, it’s time for an inspection.
When you turn, you notice the vehicle leans to one side or the other. It feels wobbly as it completes the action for the turn.
The front end dives down as you brake, especially when you hard brake. You may feel like you need to apply more pressure to come to a complete stop.
The rear squats down as you accelerate as the front end rises, especially with hard acceleration.
You feel bouncing from the tires, especially as you hit a bump or dip in the road. It may bounce for some time, or produce a clunking noise as it bounces.
You notice unusual tire wear. This is because the tires aren’t fully connecting with the road.
You notice a fluid leak around the shocks and struts. This is a sign the seal is broken and it no longer can properly function.

Is it dangerous to drive with bad shocks and struts?

In short, the answer is: Yes.

Like other parts on your vehicle, each is installed for safety and functionality. If one part isn’t working correctly, it impacts all other parts within the system.

That’s why as the pilot of your vehicle, it’s important to pay attention to how your car drives. If your car feels unstable, or it tips to the side as you drive, or you feel it bouncing with acceleration or stopping, or you see any fluid leaks, it’s time to schedule an inspection.

Shocks and struts are sold and replaced in pairs. While it’s not required to replace the front and rear shocks or struts at the same time, it’s usually suggested. Because shocks and struts wear down at the same rate, if one pair needs replacing, the others won’t be far behind it. It’s easier to get them all replaced at the same time.

Is it time to replace your shocks and struts? Have you noticed a change in the way your vehicle drives?

Don’t wait for more problems to arise, Schedule your inspection today and keep your car in good working condition. Your comfort and safety may depend on it.

CV Joint and CV Boot Repair – What You Need To Know

February 18, 2022 by Denver Express Car Care

“Your tire is flat. You’ll need to replace it.” Those words are straightforward and simple to understand. As a driver, if a mechanic gives you that advice, you may jump right on board.

But some parts are a little more difficult to understand.

“Your CV joint and CV boot are damaged and need repair.” Where do you begin?

What are a CV joint and CV boot?

CV stands for constant velocity. A CV joint (or CV axle) is used in front-wheel drive vehicles to transfer engine power to the drive wheels. It’s also used in some vehicles with independent rear suspension, as well as some four-wheel and all-wheel drive cars.

A CV axle uses two CV joints (an inner and outer joint) to transfer power to the drive wheels at a constant speed no matter what the travel conditions. That means no matter what speed the vehicle is traveling at, or the state of the road, the CV joint handles the power to ensure a safe and comfortable drive.

CV joints use grease for lubrication. To keep this grease pliable and in good working condition, the CV joints are covered with a rubber boot called a CV boot. CV boots are made from durable rubber designed to withstand extreme temperatures and driving conditions. CV boots are designed to last 100,000 miles or more. But because they are often exposed to the elements, they can and will occasionally go bad. Like other parts on a vehicle, it’s a good idea to routinely inspect CV boots to ensure they are in good working condition. If you move beyond 125,000 miles, scheduling routine inspections will ensure they stay operational and don’t leave you stranded.

How CV joints can fail

CV axles rarely fail. CV joints, however, can occasionally fail if something happens to the CV boot. When a CV boot is torn or fails due to age, the grease inside keeping the CV joints well lubricated starts to leak. It also leaves the CV joints unprotected, meaning dirt, grime, and other debris from the roadway can enter the joint. When this happens, it will eventually fail.

CV Joint and CV Boot Repair - What You Need To Know

Of the two, the outer joint will almost always fail first. That’s because more of the action is performed using this joint, and it’s also more vulnerable to the open road. If you suspect damage to the CV joints, it’s almost always the outer joint.

How CV boots can fail

If the CV boot gives out, it puts the CV joints in danger. Ensuring the CV boot is in good working condition can prevent most costly problems. CV boots can give off several warning signs of a problem:

Grease leak – it’s the most common symptom of a CV boot issue. Over time, the rubber can become dry, brittle, or crack. Once a split occurs in the rubber, grease from the CV joint can leak out. You’ll see this on the inside of the wheel, or flung onto the chassis or other parts of the underside of the vehicle as the CV joint continues to turn.

Clicking, popping, or grinding noise – if a CV boot is damaged for a while, it can lead to a CV joint becoming loose on the axle. If you hear a noise during turns, this might be the case. Most CV joints that reach this stage need replacing.

Vibrations – if a CV boot is damaged, it can allow dirt, grime, and other particles to get underneath the boot and near the CV axle. This debris causes damage, which can lead to a vibration up from the CV axle and through the steering wheel. This may only happen at certain speeds.

A CV boot is a protection device to keep the CV axle and CV joint clean and damage-free. It’s the first line of defense. To ensure a long life, keep an eye on the CV boot for potential damage, and maintain and repair it at the first sign of wear.

Inspecting the CV Axle

Whenever you suspect a problem with your vehicle, the fastest way to ensure everything is working well is to bring it in for an inspection. Trust our knowledge and experience to ensure your car is working well and won’t leave you stranded.

If you do suspect a potential problem with your CV axle, you can do a manual check at home with just a simple flashlight in hand.

First, park your car on level ground. Ensure the emergency brake is engaged.

Next, slide underneath the vehicle at front center, to be able to inspect both CV axles at the same time. Alternatively, you can slide underneath in front of one wheel at a time and inspect them separately.

Look closely at each CV axle. Each axle has two CV boots – outer and inner. Visually inspect the rubber for cracks, leaks, or other damage. If you see grease leaking, it’s a sign of wear.

If you suspect CV joint damage, you can take your vehicle out for a drive, paying attention to the way it drives. On a flat surface, such as an empty parking lot, turn the steering wheel all the way in one direction, then drive in a circle. Repeat going the opposite direction. If one of the CV joints is bad, you’ll notice a clicking or popping sound as you drive in a circle.

If the CV joint is bad enough for you to hear a clicking or popping sound while driving straight, it’s reached the end of life, and will ultimately fail soon. Schedule an appointment as soon as possible to avoid further damage, or risk being stranded by the edge of the road.

Does your vehicle need CV joint or CV boot repair?

CV boots serve as a protection device to allow the CV axles and joints to remain clean and in good working condition. To maintain a long service life, inspecting them at the first sign of potential damage is important. When in doubt, have a professional check it out. Make an appointment today.

Do All Shocks and Struts Need To Be Replaced At The Same Time?

February 3, 2022 by Denver Express Car Care

Describe your vehicle’s performance. Most people would say things about the power it has when driving on the road.

But there’s another side of performance that determines just how enjoyable the ride is.

If you’ve ever ridden in an old pickup truck, imagine how bumpy the ride was as you rambled down the road. Every bump, every pothole shot right through your system.

Now think about the ride in a high performance car. You barely heard the road. You definitely didn’t feel it. Every bump was handled with ease, barely registering on your radar.

You can thank the shocks and struts in your vehicle for that.

What’s the difference between a shock and strut?

Shocks and struts are often used interchangeably. Yet they have distinct differences. You can not substitute one for the other. If your vehicle uses struts, you cannot replace them with shocks.

A shock is the piece of the suspension system that helps coil springs absorb the impact of the road. It’s the shock’s job to take the bounce out of the movement of the car. They help keep the tires fully connected with the road instead of bouncing up as it hits different bumps in the road.

A strut combines a shock absorber and the coil spring into one single unit. While it acts as an absorber with every bump your car hits, it also provides structural support and integrity to the suspension system.

What does your vehicle use, shocks or struts?

Each wheel will either have a shock or a strut. They come in pairs. If your rear left wheel has a shock, your rear right wheel will too.

However, your vehicle may have shocks on one axle, and struts on another. Most modern vehicles have struts on the front axle, and shocks on the rear axle. You might also find struts on both axles, while it’s rare to have shocks on all four.

What does your car use?

Check your owner’s manual. If you no longer have it, a quick check online will determine what your make and model have in place.

Do All Shocks and Struts Need To Be Replaced At The Same Time?

You can also check under the car. They are easily seen if you look underneath your vehicle.

A mechanic can also tell you which components are attached to your suspension system. They can also make recommendations for replacement, when necessary.

Do shocks and struts need to be replaced at the same time?

We alluded to the answer above. Shocks and struts come in pairs. What’s located on one side of the axle will appear on the other.

Shocks and struts are always sold in pairs, and should be replaced in pairs. This provides consistency to both sides of the vehicle.

What’s more, mechanics suggest that you replace all four at the same time. This gives you a consistent response on your vehicle overall, every single bump you hit in the road.

If one set of shocks or struts wears out, chances are the other set isn’t far behind. By replacing them all at the same time, you ensure a safer, more comfortable ride.

How do you know when your shocks and struts need replacing?

Shocks and struts tend to wear out every 50,000 to 100,000 miles. The more aggressive you are on the road, the faster they will wear out. If you frequently drive on dirt roads, and love taking advantage of mountain driving, you’re more likely to replace them sooner rather than later.

Like other components, shocks and struts don’t wear out all at once. Instead, they provide warning signs of potential problems.

Bumpy ride

It might start gradually, but you’ll eventually notice your ride is getting rougher. You start to feel every bump in the road. Does your vehicle bounce more than once or twice when you hit a bump? Let it go on too long, and you’ll feel like you could lose control.

Fluid leak

Whenever you notice leaking fluid, it’s a sign to bring the car in for inspection. Leaking fluid near the exterior of the shocks and struts is a sign they’ve been compromised and they no longer have enough hydraulic fluid to do their job. If you aren’t sure if the fluid is coming from the shock absorber, wipe it down and check it again in a few miles.

Uneven tread wear

Take a look at your tire tread from time to time. It can tell you a lot about performance. If you notice wavy dips on the tread, it’s a sign you have worn shocks and struts. This is caused when the tires don’t stay firmly on the road as you drive. Instead, they bounce up from time to time, which creates uneven wear marks. This will compromise your tires faster, and decrease your stopping power.

Braking problems

A classic sign of worn out brakes and struts includes a nosedive when you hit the brakes, or swaying as you make a turn. Because the shocks and struts aren’t able to handle the changes in your vehicle’s weight distribution effectively, your car will decrease in performance.

Today’s vehicles are designed with a variety of safety systems built into the structure. Anti-lock brakes and stability control systems all rely on the various components to keep your car safe. If any piece isn’t functioning properly, it puts the entire structure at risk. Response is everything in an emergency.

The best way to know when it’s time to replace your shocks and struts is to let a technician evaluate your suspension from time to time. If you notice a sign, book your appointment sooner rather than later. Also consider creating inspection appointments at the change of seasons. This is a great way to ensure your vehicle is ready for the ice and snow of winter, and the heat of the summer.

After any suspension work, it’s a good idea for a full alignment too. This ensures your car is balanced and ready for all the driving you’ll do in the coming weeks and months.

When was the last time you had your suspension system checked? Shocks and struts need to be replaced in pairs, especially when you notice problems. If you suspect an issue, give us a call today.

Tire Alignments – The Price You’ll Pay If You Don’t Do It Often

November 18, 2021 by Denver Express Car Care

Have you noticed a change in the way your car handles while you drive?

Does your vehicle drift to the right or left while driving straight ahead?

They may be a sign of trouble with tire alignments.

What causes misaligned wheels?

When you drive your vehicle, it can undergo a lot of stress, even under normal driving conditions. Potholes, curbs, even dips in the road can all cause damage to the way your wheels operate.

Overall, there are three causes of wheel misalignment:

Sudden impact – this is caused by hitting something in the road, such as a pothole.
Worn parts – over time, parts start wearing down and can cause a problem with the way your tires connect with the road.
Height adjustments – all vehicles are designed with specific guidelines in place. If you make modifications to the parts on your car, it can impact the way it performs. This includes adjusting the height of the suspension system, without adjusting for the way the wheels connect with the road.

How do you know if the wheels are misaligned?

Like other parts on your vehicle, if tires are in need of alignment, it gives warning signals to let you know. Pay attention, and you can catch minor problems before they escalate into bigger ones.

Gas efficiency – have you noticed your fuel costs are rising? If you’re spending more at the pump without any other explanation, it could be a sign of wheel misalignment. If a vehicle doesn’t drive straight, and you’re constantly adjusting the wheel to keep the car in its lane, it increases fuel consumption for this trigger effect.

Tire wear – when tires are correctly aligned, they move in a straight line. They connect perfectly with the road, and all parts of the tire wear evenly. If tires are in need of alignment, you’ll start noticing uneven tread. That’s because you’re consistently adjusting the car to keep it on track, and various parts of the wheel are connecting with the road differently than the rest of it. This extra pressure on the tires is caused by back and forth movement, which causes premature wear and tear.

Tire Alignments - The Price You’ll Pay If You Don’t Do It Often

Drifting side to side – if you’re driving on a straight road, the steering wheel should sit straight, and your car should move forward effortlessly without adjustment. If you start feeling it drift side to side, needing more control from you to keep it within the lane, it’s a sign the wheels are misaligned.

Flats and blowouts – notice your tires are flat more often? Need to adjust the air pressure regularly? Misalignment causes tire tread to wear faster due to unequal pressure on each of the tires. That means as you drive, the tire becomes more susceptible to punctures, loss of air pressure, and eventually control over the vehicle. If the problem is allowed to persist, it puts you at more risk of a blowout, which can lead to total loss of control and cause accidents.

Unusual noises – as with other systems on your vehicle, always pay attention to the noises it makes as you drive. For example, if you hear a squeal coming from the tires as you move, it’s a sign to schedule an inspection to ensure the safety of your vehicle.

What problems can wheel misalignment cause?

Today’s vehicles have around 30,000 parts. They are all intricately designed to work together to keep you safe while you drive.

As one part wears out, it can quickly impact other parts within the system. That one part can escalate and impact a variety of components if you don’t act quickly. That also escalates the dollars you’ll spend repairing your car.

One of the most common problems with wheel misalignment is causing uneven wear on the tires. This wears out the tires faster, affects performance, and will eventually create unsafe situations, possibly from a blowout.

Misaligned wheels also show up as lower fuel economy. Because it takes more energy to keep your car under control, it shows up in the form of lowering your gas mileage. While you might not notice this right away, if you consistently track your gas mileage, you can be alerted to this potential problem quicker.

How do you fix tire alignment?

Luckily, fixing a problem with tire alignment is relatively easy to fix when you bring it into an experienced mechanic. They will use a wheel alignment machine to check the alignment and adjust the various components of your vehicle, according to the manufacturer’s guidelines of your car. They will potentially make adjustments in three different ways:

Camber – adjusting the camber means adjusting the tilt of the tire relative to the way it sits on the road. A positive camber is when the top of the tire leans away from the car, while negative camber leans towards the car.

Caster – caster involves the angle of the steering wheel pivot point as it sits according to the front and back of the vehicle. A positive caster is angled forward, while a negative caster is angled backward.

Toe – toe settings impact the vehicle’s handling related to the way the tire sits on the line of the vehicle.

Mechanics continue to refine the adjustment of the wheel until the tire alignment is straight.

How do you prevent wheel misalignment?

The best way to prevent wheel misalignment is to stick with a regular maintenance schedule. If you or a mechanic catches a problem before it escalates, you reduce the risk of potentially costly repairs, as well as accidents that can form from a damaged vehicle.

Avoid curbs and potholes – be aware of the way you drive. Avoid severe shock of the suspension system by moving slowly through dips and bumps, avoiding connection with curbs, and avoiding potholes whenever possible. If you hit a particular severe bump, it pays to schedule a maintenance visit and have your car checked out.

Avoid accidents – accidents are called accidents for a reason, yet many drivers receive minor damage regularly. If you bump a curb, back into a pole, or sideswipe a rail, it can cause extensive damage, some of it might not be immediately visible. While you might not choose to bring in your vehicle after every situation, scheduling regular checkups throughout the years can alert you to minor problems before they escalate out of control.

If you suspect your tires are out of alignment, schedule a maintenance visit soon.

Your Suspension Is Important – Here’s Why

October 7, 2021 by Denver Express Car Care

We’ve all seen the aftermath of a car out of control. The sides are crushed. The windows are broken. If it rolls, the roof may be caved in.

It’s your car’s suspension system that keeps it safely on the road.

A car can flip for a number of reasons. But if it isn’t well maintained, it increases the chance of problems occurring while driving out on the open road. Have you noticed:

Bouncing more than usual when you ride on a bumpy road
More pull in the steering wheel as you drive
It’s harder to keep control on wet roads
Traction issues as you move through curves and take turns

All of these are signs you may be experiencing problems with your suspension system.

What is a suspension system?

Your car’s suspension system is a protective layer of shock-absorbing components designed to keep your drive safe and smooth as you move down the road. It includes a variety of parts, including tires, struts, shock absorbers, steering, springs, sway bars, and axles.

The front suspension system is in charge of steering and traction functions, while the rear suspension helps keep your car stable, ensuring it doesn’t hit the ground. The two work together to keep distance between the car’s frame and the road for optimal comfort and control. The passenger cabin is designed for comfort because it’s sitting on top of the suspension connected to the wheels. It’s insulated to keep passengers from feeling every impact as it maneuvers over bumps in the road.

Your Suspension Is Important - Here’s Why

When you talk with a mechanic about your suspension system, in general, it includes:

Springs, which control the height and load
Shocks, which absorb and dampen the energy your tires transmit as they contact the road

Your car may also have an anti-sway bar to help shift the movement of your wheels as you turn the steering wheel. It stabilizes the car as you turn the steering wheel to move directions.

Why the suspension system is important

If you were to separate the suspension system from the cabin for a moment, and see the wheels in action as they move down the road, you would see the tires take the brunt of every bump in the road. Small bumps may move the tires vertically. Holes may cause the tires to move and sway. Depending on the size of the imperfection in the road will determine just how much your vehicle’s tires move and sway.

Without a suspension system, you would feel every one of these imperfections every time you hit one. Your drive would be uncomfortable at best.

The suspension system works to absorb the energy transferred through the wheels to help your car’s inside cabin stay comfortable as it rides along imperfect roads. Both the shocks and springs play a vital role in this process. The shocks absorb the energy from impact as you travel down the road, while the springs expand to dissipate the energy to prevent your car from bouncing out of control.

Combined, you get a car that stays safe and remains comfortable no matter where you drive.

You have more control through steering, and can do so with ease. The tires remain connected with the road for a safer and more stable drive. With a properly working suspension system, each part will do its job effectively without putting the other components at risk. Meaning a longer life span for your vehicle.

Signs your shocks and struts need replacing

The words “shocks and struts” are often used reciprocally, but they are two different things. Each wheel has either a shock or a strut, though many vehicles use struts on the front wheels and shocks on the rear. You can consult your owner’s manual for more information on which your vehicle uses. Or look under your car. They are easy to distinguish as long as you know what you’re looking for.

In general, shocks and struts will need replacing every 50,000 to 100,000 miles. This will change depending on your driving habits. If you frequently drive over rough roads, you will be replacing the parts on your suspension system more frequently.

Like other parts of your car, shocks and struts don’t fade all at once. Instead, they deteriorate slowly over time. You’ll start noticing signs long before your safety is put at risk.

There are four main ways your shocks and struts signal it’s time for replacement.

A bumpy ride

If you’ve started noticing your ride is rougher, it could be time to replace the parts on your suspension system. We’ve often heard drivers say, “it feels like I’m driving a truck.” Even the slightest bump in the road will cause you to sway inside your vehicle.

Leaking fluid

Shocks and struts use hydraulic fluid to complete the action. If the seal is broken and fluid leaks on the exterior of the shock or strut, it’s a sign of a problem with the suspension system. If a shock doesn’t have enough hydraulic fluid, it won’t be able to absorb impact while you drive.

Difficulty while driving

Do you notice your vehicle swaying as you take turns? Or nose diving when you hit the brakes? This is a clue the shocks and struts aren’t doing their job efficiently. They aren’t handling the weight distribution as you move through normal driving conditions. And if your car can’t stop as it’s supposed to, it’s never a good sign.

Tire tread

You can also take a look at the tire tread to determine if your suspension system is off. If you see wavy dips, also known as cupping, in the tire tread, it’s a telltale sign of the tires not completely connecting with the road as you drive. Without the shocks and struts performing their jobs, your wheels might not fully connect with the road, leaving uneven wear marks on the tires. Without proper tread, your tires may not provide thorough handling and stopping power when you need it most.

Is it time to get your suspension system checked out?

If you suspect any of these signs are causing a less than stellar drive, it’s time to let a mechanic take a look at the suspension system and ensure it’s in good working condition. It’s what keeps you and your family safe no matter what the road conditions are like on your daily drive.

When was the last time you scheduled a regular maintenance visit to determine if your car is in good working condition? Do it today.

How Potholes Damage Your Car’s Wheel Alignment and Suspension

September 7, 2021 by Denver Express Car Care

For many Colorado drivers, they don’t think about the weather. They look at the roads based on how bad the drive will be.

Winter brings ice and snow. As it melts in the spring, potholes form all over the Front Range. Then we move into construction season, before it starts all over again.

Navigating any of them could be treacherous at best. Yet in many cases, potholes can cause the most damage. How do potholes damage wheel alignment and suspension? Read on.

What are potholes?

You can’t miss a pothole if you navigate the Colorado roads. You’ll find potholes in various sizes and shapes, yet no matter how large or small they are, they have the potential to damage your car.

They form through expansion and contraction of groundwater after the water has moved past the pavement and into the ground. When temperatures fall, the water freezes and expands. This works similarly to an ice cube tray you pop into your freezer. The water may be level as you fill up the tray, but once it freezes, the ice cube may reach beyond the limits of the tray, taking up more space. This happens underground too. Water seeps in wherever there’s room. Then when it has a chance to freeze, it takes up more space, expanding, bending, and cracking the pavement wherever it lies.

How Potholes Damage Your Car’s Wheel Alignment and Suspension

When the ice melts, the pavement contracts, leaving gaps and voids underneath the pavement. This allows more water to seep in, and the process starts all over again, expanding as it goes. This leaves weak spots underneath the pavement.

As cars and trucks pass over weak spots in the road, the pavement starts to weaken. This causes the material to shift and be displaced until a pothole forms.

When CDoT adds chemicals and salt to help keep Colorado roads clear, it lowers the temperature that water will freeze. This creates and expands the cycle that allows freezing and thawing to occur, which can cause more damage to the roads.

If you’ve ever hit a pothole and immediately thought your car may have been damaged, you may be right.

What damage can be caused by potholes?

When you hit a pothole full-on, you can feel it jarring your car. The bigger the pothole, the greater risk it has of damaging your vehicle. No matter what size it is, it can be a nightmare for your wheels and suspension.

In most cases, drivers hit potholes of various sizes every day. We tend to ignore the effects because it’s a common part of our drive. It may even seem like potholes don’t impact your car. Yet the more you hit them, the more potential damage may occur. It can alter the angles of your wheels, which impacts the way it connects with the road. That can result in a safety issue over time.

Damage often starts with the wheel. If tires make direct contact, it could cause rim damage or even lead to a blowout. But it often starts in more subtle ways.

Wheel alignment is essential for the integrity of your car. When your tires are aligned, rotation follows a straight course. That means it’s easy to steer the car, and you have little resistance to keep your car on course.

A misalignment means the drive moves off-center. It becomes increasingly difficult to keep it moving in a straight line. You may feel a vibration, or feel the car pull to one side.

Misaligned wheels put undue stress on the suspension system, will decrease your fuel economy, and may impact the lifespan of your tires too. Misalignment is easy to fix; stop by for an alignment and we can have you back on the road in no time.

The longer you drive a vehicle with misaligned wheels, the more issues you’ll find throughout your car.

Tires may start to show uneven wear. This can cause them to become ineffective and unsafe if not corrected.

A bad alignment can also put more stress on the vehicle’s suspension system. Think of your car’s suspension system as a series of components that help ensure your vehicle drives safely and smoothly. It’s a kind of carriage on which the cabin of your vehicle rests. It’s comfortable because of the various working parts designed to keep your car working well. It’s an insulator to protect the passengers on the inside.

A car’s suspension includes:

Springs to help control height and load of the suspension and interior cabin
Shocks to help absorb and dampen energy as it moves from the road, through the tires, and into your vehicle

The suspension also has an anti-sway bar to help with movement from your wheels to the steering wheel. This is what stabilizes your vehicle as it travels across the road.

How you hit potholes matters

When you come to a speed bump or dip in the road, it’s only natural to slow down to create less impact on your vehicle. Hitting a pothole doesn’t work in the same manner.

If you can’t steer around it, it’s better to hit it without applying the brakes. Your natural reaction might be to press down on the brake pedal to lessen the impact. That can actually cause more damage. When you apply the brakes, your car’s front end dips down as the suspension slows the front wheels. This compression causes the wheels not to absorb as much of the road impact. Which ultimately can lead to more serious damage throughout your vehicle.

Braking for potholes can be especially damaging to shocks and struts. Because shocks and struts affect alignment, if they are damaged, chances are your alignment is thrown off too.

Have potholes impacted your vehicle?

How many potholes have you hit this season? Lost count?

While your vehicle can navigate the roadway without issue in most cases, over time potholes can impact the performance of your vehicle.

Noticed it’s harder to control the car? Does it sway to the right or left? Do you feel a vibration as you drive? All could be problems with your wheel alignment. And if not corrected, it could do more damage to your suspension.

Stop by today, and we’ll have you back on the road safely in no time.

Are You Properly Towing Your Trailer? If Not, It Might Be Impacting Your Brakes and Suspension

August 25, 2021 by Denver Express Car Care

You don’t have to look any further than your local highway to know Coloradans love taking vacations. Trucks and SUVs are towing trailers, heading out into the high country to take advantage of all Colorado has to offer.

But did you know that towing a trailer has a huge impact on your brakes and suspension? If you aren’t aware of proper towing know-how, you could be putting a lot at risk. Improper towing could damage your car’s brakes, suspension, tires, transmission, and even impact your alignment. Your fun trip to the middle of nowhere could turn into one giant headache if you’re not adequately prepared.

Are you properly towing your trailer? Are your brakes and suspension at risk? Here are a few questions to keep in mind.

How much can your vehicle really tow?

You have a truck. You just bought a trailer. What could go wrong?

Quite a lot if the two aren’t properly paired. It’s important to understand how much your vehicle can tow before you purchase a trailer. If the trailer is too large for your vehicle, it can damage the suspension, transmission, even your engine.

Your vehicle comes with a towing capacity. The conventional towing capacity is regarded as how much it can pull with a frame-mounted hitch. Fifth wheel towing capacity would be mounted directly in the bed of your truck. Check with the owner’s manual to find out how much weight your vehicle can handle. This is the maximum weight it can pull without damaging the vehicle. Keep in mind that if you add other items to the trailer after you purchase it, it will add to the weight capacity. Make sure you stay within limits to ensure safety precautions.

Do you have the proper equipment?

Have you changed vehicles? Upgraded the trailer? Have a different combination than what you started with years before?

Not all equipment works in every situation. Towing requires four main pieces of equipment: a hitch, a receiver, a drawbar, and a hitch ball. Each of these parts work together to keep your vehicle and your trailer properly connected.

The hitch attaches directly to your vehicle and provides the connection between the vehicle and the trailer. A hitch class 1 tows up to 2,000 pounds, class 2 up to 3,500 pounds, class 3 up to 8,000 pounds, and class ⅘ up to 18,000 pounds. Hitches must be married up to the right vehicle to ensure proper towing capacity.

The receiver is the base for all other elements, and is appropriately sized depending on the different load sizes.

The drawbar is a tube that threads between the receiver and the hitch ball. You can buy an adjustable height to ensure you create a level plane no matter what load you’re towing.

The hitch ball comes in multiple sizes and is designed for varying amounts of weight.

These items are not interchangeable. You have to have the proper equipment as you move from towing your boat, to your trailer, to a mini-camper. Always ensure you have the proper equipment to remain safe at all times.

Have you thought about all of the details?

You have a truck or an SUV. You’ve purchased a new trailer. You’re about to head out on the open road. What could go wrong?

A lot if you’re not diligent about the details. Safety checks are mandatory to ensure your vehicle stays safe.

When you’re towing, you should ensure you have trailer lights to assure other drivers know what you’re doing. Do they operate correctly? Do they mimic your taillights and respond correctly to what you signal from your vehicle?

Have you used extra support chains to provide additional support connecting your vehicle to the trailer? This can prevent your trailer from careening into another vehicle if something should go wrong with the hitch.

Have you secured your load? Are all doors shut and properly locked? Is everything secured so it won’t fly out when you hit highway speeds?

Have you checked the laws for where you’re going? Different states have different rules. If you are spending time in a location, you may be required to match those laws with your own setup. Paying attention before you leave can prevent headaches down the road.

Check your tires regularly – all of them. If they aren’t properly inflated and in good working condition, they can become a danger out on the open road. This includes the trailer tires. A check up before you leave will ensure you don’t have tire troubles later. Look for worn spots, improper wheel alignment, or tires that simply aren’t up for the job you’re about to undertake.

Is it time to invest in additional performance options?

Chances are if you’re investing in a vehicle and trailer, this will be more than a one-time event. Think clearly about your long-term expectations, and find performance options that can help you stay safer.

For example, you can find a lot of additional parts that can make a difference in the way your vehicle moves and operates. How about a set of helper springs that help absorb the shock as your vehicle moves. They can assist with adding extra support to the springs and shocks, cushioning the action with every bump you hit in the road.

Or maybe an enhanced exhaust system to help release back pressure from the engine. This can help the engine breathe easier, which can be important especially if you’re heading into the Rocky Mountains.

No matter what you decide, the key to staying safe is to ensure they are all properly maintained for as long as they are in use.

Are you ready to go?

Before you head out on your next great adventure, ensure both your vehicle and trailer are in excellent shape.

Existing brake problems will only be exacerbated by towing a heavy load.

Worn tires or improper wheel alignment can spell disaster as you weave around curvy roads.

And the added weight can quickly impact your suspension, putting you more at risk of collision.

The best way to prevent all that is through regular maintenance. If you’ll be towing a trailer in the near future, let us know. We’ll check your vehicle out thoroughly to ensure it’s ready for the job.

And have fun on your next vacation!
