2. The inner ends of the drive shafts are equipped with sliding joints of equal angular speeds, which have the possibility of angular and axial movement. Models with automatic transmission are fitted with three-finger inboard joints. Models with a manual transmission are equipped with internal ball 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 hinge must be replaced.
3. Equal velocity joints are installed at the outer ends of the shafts "ball" types that allow only angular movements. External connections can be removed, cleaned and the protective cover replaced, but they are non-separable. If the outer joint is damaged, it must be replaced along with the drive link (outer joint and drive shaft are one piece).
4. Periodically inspect the protective covers to ensure that there is no damage or evidence of grease leakage. If the protective covers are damaged, they must be replaced immediately to prevent breakage of the constant velocity joints. To replace the protective sheath, it is necessary to remove the drive shaft (see paragraph 11).
Note: Replacement boots may be designed to fit without removing the drive shaft. This is convenient, but is only a temporary measure.
In addition, it is desirable to remove the drive shaft in order to make sure that the constant velocity joint is not dirty. Otherwise, the hinge will quickly fail. Usually a sign of joint wear (except for traces of lubricant leakage) is the appearance of clicks when the car is moving around a corner, clanging when accelerating after coasting, and vibration when driving at high speed. To check the hinge, grasp the ends of the hinge with your hands and rotate them in opposite directions. When worn, you will feel the presence of play in the hinge. Also inspect the shaft ends for cracks, dents, or other damage.
