1. Protective covers of drive shafts are very important elements, because. they protect the constant velocity joints (SHRUS) from contact with dirt, water and other foreign bodies that cause damage. External contamination of protective covers with oil and grease can lead to premature failure of the material of the covers, so it is recommended to periodically wash the covers with soap and water.
2. Inspect boots for tears, cracks, and loose clamps. If there are signs of cracks or leakage of lubricant, the cover must be replaced.
3. At the same time, check the general condition of the CV joints by holding the shaft and at the same time trying to turn the wheel. Try again while holding the inner CV joint and turning the shaft. Any noticeable play indicates wear on the pivot, wear in the shaft slots, or a loose shaft lock nut.
