Drive from the differential axle gears to the front wheels is transmitted by two steel drive shafts of unequal length. On some models, the right (longer) the drive shaft is equipped with a dynamic vibration damper, designed to reduce its vibrations and prevent resonance.
The outer ends of both drive shafts are splined to accept the wheel hubs, and are threaded to allow each hub to be secured with a large nut. The inner end of each drive shaft is also splined (for connection with differential axle gear) and has a groove for a retaining ring that secures the drive shaft to the axle gear.
Each drive shaft is equipped with two CV joints, designed to ensure smooth and efficient transmission of drive at all possible angles when the vehicle is moving (the movement of the wheels up and down with the suspension and from side to side with the steering gear). The outer CV joints are ball joints of the Birfield-Rzeppa brand, and the inner ones are tripod type, allowing a slight change in the effective length of the drive shaft at the extreme positions of the suspension components.
Note: If necessary, only the CV joint assemblies, rubber boots and their clamps, the drive shafts themselves and the various retaining rings can be replaced. If any of the CV joints are worn or damaged, it cannot be repaired and must be replaced as an assembly. After removing a component, be sure to replace all associated retaining rings. In addition, it is not recommended to reuse the clamps of the protective boots.
