Every 16,000 km or 12 months.
1. Rubber boots on the drive shafts are important because they protect the constant velocity joints from dirt, water and foreign particles, and thus prevent the joints from being damaged. Outdoor dirt can cause degradation of the cover material, so it makes sense to occasionally wash covers with soap and water.
2. After lifting the vehicle and placing it on supports, turn the steering wheel to the stop, and then slowly rotate each of the front wheels in turn. Check the condition of the outer rubber boots of the constant velocity joints by opening the folds (see fig. 16.2). Look out for cracks or cracks in the rubber, as such defects can lead to loss of lubrication and infiltration of water and dirt into the joint. Check up also a condition and reliability of fastening of collars. Repeat the same checks for the inner hinges. Covers must be replaced if damaged (chapter 8).
3. At the same time check up a condition of hinges. To do this, while holding the drive shaft, try to turn the wheel. Repeat check for internal hinges. To do this, while holding the fork of the internal hinge, try to turn the drive shaft.
4. The presence of play in the joint indicates wear of the joint, wear of the splines of the input shaft, or loosening of the input shaft mounting nut.
