2. The inner ends of the drive shafts are equipped with sliding constant velocity joints, which have the ability to move angularly and axially. Models with automatic transmission are equipped with three-pin internal joints. Models with a manual transmission are equipped with ball-type internal joints. If the protective cover is damaged, the hinge must be disassembled and cleaned (see paragraph 13). However, if the hinge components are damaged, the entire joint must be replaced.
3. At the outer ends of the shafts, constant velocity joints of the "ball" type are installed, which allow only angular movements. The external connections can be removed, cleaned and the protective cover replaced, but they are not detachable. If the outer joint is damaged, it must be replaced along with the drive axle (the outer joint and the drive shaft are one piece).
4. Periodically inspect the protective covers to ensure there is no damage or signs of grease leakage. If the protective covers are damaged, they must be replaced immediately to prevent damage to the constant velocity joints. To replace the protective cap, it is necessary to remove the drive shaft (see paragraph 11).
Note: Replacement boots may be designed to be installed without removing the drive shaft. This is convenient, but it is only a temporary measure.

In addition, it is advisable to remove the drive shaft to ensure that the constant velocity joint is not contaminated. Otherwise, the hinge will quickly fail. Usually a sign of wear on the hinge (except for traces of grease leakage) is the appearance of clicking sounds when the car is moving on a turn, a clanking sound when accelerating after coasting, and vibration when moving at high speed. To check the hinge, grasp its ends with your hands and rotate them in opposite directions. When worn, you will feel play in the hinge. Also inspect the shaft ends for cracks, dents, or other damage.
