Pic. 5.1. Check the condition of the axle shaft boot (marked with an arrow)
2. At the same time, check the general condition of the outer CV joints themselves, first holding the axle shaft and trying to rotate the wheel. Repeat this test on the inner joints, holding the joint and trying to rotate the axle shaft. Any noticeable movement is a sign of wear on the hinges, half shaft splines or loosening of the half shaft fastening nut.
