2. Turn the steering wheel all the way and slowly rotate the wheel.
3. Check the condition of the rubber boot of the outer CV joint by spreading the folds of the boot. Check for cracks, tears and signs of rubber aging, which may cause grease to be washed out and dirt and water to get inside the joint. Also check the tightness and condition of the spring retaining rings.
4. Repeat the same steps for the inner CV joint. If any damage or signs of wear are found, the boots should be replaced (see subsection 10.4).
5. At the same time, check the condition of the CV joints themselves, for which, holding the axle shaft, try to turn the wheel.
6. Then try to turn the axle shaft while holding the inner joint. Any noticeable play indicates wear of the joint splines, axle shaft splines, or a loose axle shaft nut.
