1. Turn the steering wheel as far as possible, then turn the wheel slowly. Check the condition of the rubber protective covers of the outer CV joints. Check them for signs of cracking or rubber contamination that could allow grease to leak out (refer to accompanying illustration). Also check the reliability and condition of the mounting brackets. Repeat these checks on the inner CV joints. If any damage or contamination is found, the protective covers should be replaced (see chapter Drive shafts).
2. At the same time, check the general condition of the CV joints. Hold the drive shaft with one hand and try to turn the wheel with the other. Repeat this test while holding the inner joint and rotating the drive shaft. Any noticeable movement indicates wear in the joints, in the grooves in the drive shaft, or a loose drive shaft mounting nut.
