The axle assemblies in your vehicle transfer power out to the drive wheels. On the rear-wheel drive vehicle, there is an axle shaft that goes from the differential in the center of the axle to each of the rear wheels. On the front-wheel drive vehicle, the axle shafts go from the transmission to each front-wheel. All-wheel drive vehicles have axle shafts connected to all four wheels.
Axle assemblies are pretty tough parts: they transfer torque from the engine to the wheels to move the vehicle. Tough as they are, they are still subject to normal wear and tear. The axle shafts are in a sealed housing with lubricant that protects the axle shaft. When there is a leak anywhere in the axle assembly, lubricant gets out and dirt, water and other contaminates can get in. This can greatly accelerate axle wear. If an axle assembly fails, you’re not going anywhere.
A worn or damaged axle assembly on the front will make a clunking sound during low speed turns – often just when turning one way. A worn rear axle also makes noise but may be more difficult for the driver to hear. Also, if you see any oily leaks around your wheels, have them checked out.
If you have a bad axle assembly, your Express Car Care technician can make the repair. It is often more cost effective to replace an axle assembly than it is to take it apart and rebuild it.
If you are hearing strange sounds coming from your front or rear wheel area, have Express Car Care inspect your vehicle. We can determine if it is an axle problem or perhaps a worn steering, suspension or brake component.
