Checking the condition of the protective covers of the drive shafts (Audi A4 B6)

1. Protective covers of drive shafts are very important elements, as they protect constant velocity joints (CV joints) from dirt, water and other foreign objects that cause damage. External contamination of protective covers with oil and grease can lead to premature failure of the cover material, so it is recommended to periodically wash the covers with soap and water.

2. Raise and place the vehicle on stands.

3. Remove the lower engine compartment cover, refer to Section Removal and installation the upper engine cover/lower engine compartment protection/subframe.

4. Shine a light on the protective covers (1) and check them for cracks. Pay attention to the presence of traces of grease on and near the covers. If signs of cracks or grease leakage are detected, the cover must be replaced.



5. If the cover is pulled inward or damaged, it must be replaced immediately.

6. Check the reliability of the clamps (2).

7. At the same time, check the general condition of the constant velocity joints by holding the shaft and trying to turn the wheel. Try again by holding the inner constant velocity joint and turning the shaft. Any noticeable play indicates wear in the joint, wear in the shaft grooves, or loosening of the shaft lock nut.



8. Replace the lower engine compartment cover.

9. Lower the car onto its wheels.
