The driveshaft rubber gaiters have an important role in ensuring that dirt, water and other foreign materials are prevented from entering and damaging the joints since external contamination may cause premature deterioration of the gaiter material, and it is advisable, therefore, to wash the gaiters in soap and water from time to time. When the vehicle is raised and firmly supported on the axle stands, if the steering is turned to full-lock condition, one can thoroughly inspect the outer constant velocity (CV) joint rubber gaiters by making a 360-degree rotation to each of the front wheels and squeezing the gaiters to determine if they have cracks, splits, or deterioration that could lead to grease escape and the ingress of water and grit. It's also important to check the security and condition of the retaining clips, and also do the same on the inner tripod joints. If any damage or deterioration is found the gaiters should be replaced. Additionally, the general condition of the outer CV joints should be assessed by holding the driveshaft and trying to rotate the wheels and then doing the same for the inner joints by holding the inner joint yoke and trying to rotate the driveshaft. Any noticeable movement in the joint may indicate wear in the joint, wear in the driveshaft splines or a loose driveshaft retaining nut.
