Constant-velocity joint (CV) boots play a crucial role, preventing water and dirt from entering the CV joints. Fuel or grease coming into contact with the boots can cause them to deteriorate, so it's recommended to wash them with soap and water.
Figure 2.26. Inspection of the protective boot of the constant velocity joint of the drive shaft
Raise the car on a lift, raising the front wheels. Turn the steering wheel all the way to the right or left and turn the wheel. Inspect the rubber CV joint boots by squeezing them to open the folds (figure 2.26). Check them for cracks that could allow grease to leak and water and dirt to get inside. Check the condition of the mounting clamps, inspect the inner hinge covers and the casings on the other side. Replace any damaged protective cover immediately.
Check the condition of the constant velocity joints: after fixing the drive shaft, try to turn the wheel. Try again while holding the inner constant velocity joint and turning the drive shaft. Any noticeable play indicates wear in the joint, wear in the shaft grooves, or looseness of the shaft lock nut.
