With the vehicle raised and securely supported on stands, slowly rotate the rear roadwheel while inspecting the condition of the outer constant velocity (CV) joint rubber gaiters by squeezing them to open out the folds. Look for signs of cracking, splits, or deterioration of the rubber, which may allow grease to escape and lead to water and grit entry into the joint, and also check the security and condition of the retaining clips. Repeat these checks on the inner CV joints, and if any damage or deterioration is found, the gaiters should be renewed. Simultaneously, assess the general condition of the CV joints by holding the driveshaft and attempting to rotate the wheel, then repeat this check by holding the inner joint and attempting to rotate the driveshaft; any appreciable movement indicates wear in the joints, wear in the driveshaft splines, or a loose driveshaft retaining nut.
