When these parts go bad you’ll hear or feel a clicking or throbbing when you make a turn. Test this by driving around in a parking lot. If you find clicking or a crackling noise, you need to replace the parts immediately.
Drive Axles transmit energy from the engine to the wheels. A front-wheel drive car typically has two “half-axles” that get power from a single transmission and convey rotation to each front wheel. Between the transmission and each wheel are an axle, differential and universal joints. Drive Axles on your vehicle are structural components that connect the pairs of wheels on opposite sides (left and right). They maintain the wheel alignment and their position relative to each other and to the vehicle body. The axle may be a single solid shaft (in the rear) or a flexible assembly (in front) but either way, the axles are designed to bear the weight of the vehicle (and all its cargo) and handle all the dynamic forces of you in motion.
There are also constant-velocity (CV) joints that allow the axle to transmit power at a constant rate without increased friction and heat. CV joints are very reliable so long as they’re lubricated. The most common problem with them comes if the “boot” that protects the joint is damaged. Once exposed to dirt and increased friction (from loss of lubrication) the joint will deteriorate quickly.
CV joints and Drive Axles should be inspected regularly. At Gerry's, we inspect them with every oil change to make sure that you stay on the road longer without serious problems.
