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? 

Are You Properly Towing Your Trailer

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!

What a Shaking Steering Wheel Means

July 14, 2021 by Denver Express Car Care

Shake, rattle, and roll. Throw in a catchy beat, and you have the makings of a great song. 

But if you start feeling your steering wheel shaking while you drive, that can be the start of something you won’t be singing about for very long. 

A shaking steering wheel is a symptom of a bigger problem. From bad tires to worn out brakes, there are a variety of issues that could be causing your steering wheel to shake. If you feel shaking, start noticing when it occurs. That can help lead to where the problem lies. 

Tires out of balance

One of the most common reasons that might start your steering wheel shaking starts with your tires. They may be out of alignment or out of balance, which sends shaking through your vehicle and into your steering wheel. 

If your tires are out of balance, you won’t notice this as you’re pulling out of the driveway, or moving at low speeds due to traffic. But as you pick up speed, the shaking will increase. That’s because tires out of balance start becoming a bigger problem the faster you drive. Slow down, and it goes away. 

The first thing to check is a visual inspection of all four tires. Are they properly inflated? Is one of them flat? Your car is designed to operate with all four tires evenly connected to the road as you drive. If one of them has lower air pressure than the others, it can throw the balance of your car off. 

If all tires are inflated correctly, the next thing to check is the tread on the tires. In order to keep the tread even on all four tires, it’s important to get them rotated periodically throughout the year. You can have this done at the same time as an oil change. This will ensure even wear for the life of your tires. It also keeps your car evenly connected to the road, meaning a smoother, safer drive for you. 

What a Shaking Steering Wheel Means

If the problem persists, it’s time to look at other potential problems.

Worn brake pads

Have you noticed that your steering wheel shakes only after you press down on the brake pedal? It might be a sign of worn brake pads. 

As you apply the brake pedal, a caliper applies pressure to the brake pad, which in turn connects with the rotor to slow you down. This slows you down until ultimately, you come to a stop. If anything happens during this process, you might feel a shake coming through the steering wheel. 

If it’s your brake pads, it’s usually because they are old, work, or dirty and can no longer grip the rotor effectively to bring your vehicle to a stop. The brake pad connects unevenly, which causes the skipping movement which vibrates up into your steering wheel. 

Calipers are designed to last. The problem usually stems from the brake pads, which have to be replaced on average about every 10,000 to 20,000 miles. It can also be from the brake rotors, which may need replacing every 70,000 or so miles. This depends on your driving conditions, how you drive, the weight of your vehicle, among other things. 

Suspension

The suspension can also be a common occurrence for a shaking steering wheel. This is especially true with vehicles that aren’t properly maintained, and haven’t been closely evaluated by a mechanic over time. That’s because suspension problems rarely surface overnight. Instead, they develop slowly over time. 

What can cause it? It might be a loose tie rod, or a ball joint that wiggles out of position. It might start with an odd, subtle noise, one you put off because you don’t notice changes right away in the way your car operates. This is also why it’s important to pay attention to any changes in the way your vehicle operates, and provide any noticeable differences to the mechanic in charge of working on your car. It can lead to pinpointing a problem that might not have surfaced without it. 

Dry guide pins

Guide pins are part of the brake calipers. Over time, they can slow down from dirt and lack of lubrication. To keep them performing well, they need to be periodically cleaned and lubricated or they become dry and corroded. This means they don’t apply the correct pressure as you press down on the brake pedal, which can cause the brake pad to connect with the rotor at the wrong angle. And when that happens, it produces a vibrating steering wheel. 

This is detailed work. A trusted mechanic will inspect the entire brake system, including the caliper housing to ensure it’s handling the lubricant correctly throughout the process. If a problem exists, correcting it early will ensure parts don’t wear down before their time. 

Do you have a shaking steering wheel?

Once you notice even a slight shake, it’s hard to ignore it. Don’t. Even a slight shake from time to time is a warning sign of future problems. 

Do a search online and you’ll find all kinds of horror stories about faulty equipment. In almost every case, horror stories are caused by people who ignored the warning signals. 

Even a tiny shake is trying to alert you to a problem. Take note of the details and bring it in. We can properly diagnose it, find the origination point of the problem, and fix it before it has a chance to grow. 

The best course of action will depend on the specific problem. But if you catch it early, you’ll reduce the chances of having an expensive problem that moves to different locations throughout your vehicle. 

While every part of your vehicle is important in helping to keep you safe and secure, any indication of a problem with your braking system should be checked immediately. If a problem threatens the longevity or safety of your car, fix it early to ensure you’re back on the road safely again. 

Just in time to turn up the radio and start singing your favorite tunes once again.

Growling that Grates

March 29, 2021 by Denver Express Car Care

A driver who uses his or her ears has a leg up on those who don’t.  Noises, in addition to helping us to be aware of traffic, can also give us clues to potential problems in our vehicles.  One noise to pay special attention to is growling.

Growling is a universally recognizable noise; you know it when you hear it.  In a vehicle, it’s usually the sound of metal contacting metal, and not in a good way.  So, what is your vehicle telling you if you hear growling when you are turning your steering wheel?

There are a few possibilities.  One is the mechanical linkage that helps your steering wheel turn your wheels and tires.  This system frequently has a hydraulic system that makes turning the steering wheel easier for you.  This can be one source of growling sounds you might hear.  An auto technician can check your power steering fluid to see if it’s at the correct level and still has a good consistency.

There are a few things that can go wrong with your power steering.  If your fluid is low, that might be a sign of a leak in the pump, hose, or somewhere else in the system.  It’s important to have your power steering working properly since losing the ability to turn precisely can sharply reduce the safety of your vehicle.

If that growling sound is coming from around the wheel area, it could be a suspension issue.  That growling is giving you a warning that a component such as a constant velocity (CV) joint or a wheel hub may be on the verge of failing, so it’s a good idea to get it checked right away.  Another reason you may be hearing growling when you turn your steering wheel is that your brakes are engaging when they shouldn’t.

Growling noises are trying to tell you something, and they can tell a trained technician a great deal.  Inform your service adviser about the symptoms you’re hearing or seeing.  Your Express Car Care service provider can put that growling to a an end.  Your ears will thank you.

A Guide To Power Steering

March 10, 2021 by Denver Express Car Care

If you were to jump behind the wheel of a car built in the 1950s or before, you’d notice a lot of changes from our modern technology. While you could quickly adjust to seat comfort, noise levels, or even the lack of accessories, the one thing you might have problems with is the way the car drives.

Power steering may just be one of the single most effective systems adding into the modern day driving experience.

Without power steering, steering wheels were much larger in size. That was to give the driver leverage when trying to turn the wheels. As power steering was added, it became easier than ever to control the wheels with just slight variations of the steering wheel. It shrunk in size to add more comfort to the passenger cabin.

The power steering wheel

The original power steering wheel was added to enhance the feel for the driver. When you have more control, it reduces risk.

To create movement in the steering system, it’s achieved with a gear system. If you’ve ever heard the term “rack and pinion”, it’s referring to the steering system.

A Guide To Power SteeringThe rack is linear rather than round. It’s long and flat with prongs on one side. The rack is attached to the steering column by a series of tie rods.

The pinion is a circular gear that connects the steering shaft to the steering wheel. As you turn the steering wheel, the pinion rotates, moving the rack back and forth to control the vehicle to turn left or right.

The difference between hydraulic and electric power steering

While power steering changed everything, since it was first introduced in the 1950s, it has seen its share of changes.

The rack and pinion gear is also referred to as hydraulic, or HPS (high pressure steering.) These are considered steering assistance programs. If something happens to the engine, these steering assistance systems will give the driver control to steer even if fluid isn’t being supplied to the steering gear. Hydraulic steering uses the power supplied from the engine uses a belt attached to a pump, which continues to circulate fluid throughout the system.

Power flows because of the fluid. The power steering pump circulates this fluid under intense pressure, moving the pistons that control gear shifting, requiring less effort from the movement of the steering wheel. Pressure builds, the piston moves, and you have the ability to shift the car left or right with gentle motions. With technology, this process has sensors which can also take into consideration the vehicle’s speed, which ensures all movement is appropriate for the rate at which you are traveling.

Electric power steering, or EPS, is a bit simpler thanks to technology. It’s the vehicle’s computer system that is in charge of the steering process. The vehicle is equipped with a small electric motor either on the steering column or on the steering rack. Because the EPS doesn’t rely on power from the engine, it can increase fuel efficiency as well.

As a driver turns the steering wheel, the computer translates the movement and sends the request to the electric motor. This moves the rack and pinion back and forth. It’s built similarly to the hydraulic system in that it increases sensitivity at higher speeds. Because the only fluid in the system is to move the rack and pinion, it does not require fluid flushes as the hydraulic system does.

Common power steering problems

Like every part of your vehicle, the car is designed to give small warning signs as to when your power steering is failing. Watch for:

Power steering fluid leaks – power steering fluid is used to transfer pressure within the system, and change the direction of your wheels. If this fluid system has been compromised and is leaking fluid, the ability to build up enough pressure to move the wheels will be harder to do. You’ll notice it in the turning radius of your steering wheel – what used to be simpler grows harder to process. You can easily spot a leak because you’ll notice fluid dripping from the vehicle. There is often a grinding noise that is heard as you attempt to turn. If you ignore the problem to the point the system runs out of fuel, it can burn out the power steering pump.

Worn out hose – all parts are submitted to extreme conditions as you drive throughout the year. Often, one of the first to go are hoses as they crack, peel, or break. If the rubber hardens, it suffers more under intense conditions. This can be one of the first sources of a power steering fluid leak.

Slipped belt – occasionally, the drive belt will slip off the power steering pump. You’ll notice this by a squealing sound as you move your wheel to the left. This will prevent your car from changing direction as the pump won’t be able to do its job because of a total loss of fluid pressure.

Worn out pump – as a car ages, it causes the power steering pump to wear down. The seals can fail, the pump can break down, all leading to a loss of fluid pressure. The squealing noise will increase as you use it, and you’ll eventually lose the ability to steer at all.

How do you prevent problems with your power steering?

Preventative maintenance is your best course of action. Through a routine inspection, one of our mechanics can test each system and determine where weaknesses lie. You’ll learn which parts should be replaced, what signs to watch for, and be able to make decisions about the risk levels of your auto.

Are Suspension Systems Different In Pickup Trucks Than In Cars?

February 18, 2021 by Denver Express Car Care

Since the very first horseless carriage was created, focus has been placed on creating a smooth ride. Imagine the first vehicle hitting a rock or a dip in the road – there wasn’t pavement back when the first vehicle was moving around.

Every bump moved from the wheels into the car, jostling the passengers around.

As more cars were built and sold, more time was spent on keeping the passengers safe, comfortable, and happy. Suspension systems are designed to provide each of these things and more.

What is a suspension system?

The suspension system includes all of the parts in the body of the car that allow it to connect with the road – wheels, tires, brakes – as well as the parts that help each of those systems operate – springs, shock absorbers, and other hardware. A suspension system is designed to support the weight of the vehicle, to absorb the shock that comes up into the vehicle with every bump and movement it makes, as well as provide a pivot point for the wheels. Its ultimate goal is to provide passengers with a smooth ride, while keeping you and the vehicle safe during the process.

A suspension system works to absorb the shock when you hit a bump, as well as to decrease the impact sent up through the axel and into the passenger section. The two are connected, yet through a variety of components, it’s designed to lessen the impact. How this occurs often determines the comfort level of the vehicle. This is where trucks and cars move apart.

Front end suspension systems 

Most passenger cars and light trucks on the market today use a front suspension system. This includes a conventional coil spring, a Torsion Bar, and MacPherson Strut systems. You’ll find full-sized vehicles use a coil spring or the torsion bar systems frequently, while struts are more widely used on import vehicles and newer domestic vehicles.

No matter how it’s constructed, all suspension systems are designed for the same function – they support the vehicle to maintain proper wheel alignment, to connect with the road efficiently, and to absorb road shock as it moves up through the tires. How this is accomplished may change from system to system, but the final impact is always the same.

Are Suspension Systems Different In Pickup Trucks Than In Cars?A coil spring system works by supporting the weight of the vehicle on coil springs and controlling impact by spring weight. The springs are mounted on either the upper or lower control arm, which also determines where the ball joint will be placed. The load-carrying ball joint is always on the same control arm with the spring.

With the torsion bar system, the vehicle’s weight is supported by the twisting of the bar. The torsion bar performs the same function from above as the coil spring in the vehicle.

With the MacPherson struts, the shock absorber, coil spring, and axis pivot have all been combined into one strut assembly. The weight of the vehicle is supported at the top of the spring plate, while the shock absorber dampens vibrations as the coil spring controls the ride.

Rear suspension systems

Most read wheel drive vehicles on the road today use a leaf spring and coil spring suspension.

They are designed with a solid axle that has some of the same characteristics as a solid axle front system. But the difference lies in movement – the rear wheels don’t pivot. Because more cars are coming with front wheel drive systems, you’ll also find more independent rear suspension systems. They offer improved performance and better control overall.

With a leaf spring system, the control arms are eliminated. A U-bolt connects the springs to the axle, which in turn connects the spring to the frame.

With a coil spring system, the coils sit on the axle housing on the underside of the vehicle. Movement is handled through control arms.

With an independent rear system, it’s used on a non-solid axle. This means that the vehicle will pivot independently based on suspension movement. This encourages better traction, since the wheels have flexibility in the angles they turn to as the wheels turn and move. This provides better acceleration and braking, and less resistance overall.

While independent systems provide better driving ability, it also adds more wearability to your vehicle. Because the wheels act independently of one another, each side must be aligned to the other, as well as to both front wheels. More parts, more servicing, which ultimately means more cost. But for increased safety, it’s worth the effort.

Car vs truck – what’s the difference?

Every car and truck is designed as the manufacturer chooses to produce it. Traditionally manufacturers used a leaf spring layout for the suspension system because they felt it was the safest for heavy loads. However, rules are always meant to be broken, and many have deviated and tried other things.

While most cars on the road today will use front and rear independent suspension systems for maximum control and comfort, many trucks also move to live axles placed at all four wheels.

It’s the shock absorbers’ job to control the axle’s motion as it takes in every bump in the road. For a truck, this task requires different degrees of control, which requires a heavier duty component the more weight you carry.

Trucks also have other considerations for the way they move. Many trucks need ground clearance and lift kits to ensure they navigate safely over rough roads. That means the suspension system must be longer to travel and up and down with every bump it takes in.

Off-road driving can also increase heat. The shock absorber must be able to dissipate that heat as it’s generated in each of the conditions you may put it through. From hauling to off-roading, the suspension system has to be ready for the job at hand.

When was the last time you had your suspension system thoroughly evaluated, to ensure your comfort and your safety? Suspension systems send out early warning signals about potential problems. Are you paying attention to what your vehicle is trying to tell you?

Ball Joint Boot Replacement

February 1, 2021 by Denver Express Car Care

There’s a little part on your vehicle you may not know about, but when it develops a problem, getting it fixed sooner rather than later can save you a lot of money in the long run.  Have I got your attention now?

This part is called a ball joint boot.  Ball joints are part of your suspension and allow your front wheels to move up and down and turn left and right.  This boot covers and protects your ball joint.

Your suspension is, of course, exposed to nasty stuff getting kicked up from the road.  Stuff like rocks, salt, water, dirt, and chunks of asphalt.  If all that debris were constantly hitting your ball joints, they wouldn’t last very long.  So someone had the bright idea to include protective “boots” that go over the ball joints.  Great idea and they work…for a while.  Just like every other part on our vehicles, they will need to be replaced eventually.

These boots not only protect against debris but they also protect against heat and friction.  Because of this, they must be flexible.  In addition to keeping contaminants out of your ball joints, they also keep lubricants in and allow the hot grease to expand.  This is vital to make sure metal parts are moving smoothly.

Sometimes the ball joint boots get damaged after constant assault by road junk or temperature extremes.  Other times they just get old.  Rubber and other flexible materials can eventually just wear out (think of old rubber bands that break because they’re brittle from age).  A regular suspension inspection will assess the condition of your ball joint boots.  When your Express Car Care service adviser says there’s a problem with one of your ball joint boots, heed the warning.  If they have a tear in them and aren’t replaced, lubricant can escape the ball joint and debris can get in and start creating a destructive mess.

Also keep in mind that if a ball joint is bad on one side, the other side might be on the verge of going too.  Replacing both ball joints and ball joint boots at the same time saves time and money and just makes sense.
