What Are CV Boots & Joints

By October 24, 2017Gresham Auto Repair

Most front wheel drive cars transmit power to the wheels through flexible axles call Constant Velocity Joints and are attached to the drive shaft. These are covered with rubber boots and packed with grease to lubricate the joint and keep water and debris out. If the rubber boots deteriorate and split open, the protective grease is slung out with the spinning of the axle. When this happens moisture and road grime get into the joint causing it to fail. Caught early, you may only need to replace the boot; most often however, the entire axle may need to be replaced. If you hear a clicking or popping noise when turning, this could be the problem.
