Note: If the drive shaft mounting bolt is loosened by more than 30°, the wheel bearing must not be loaded by the weight of the vehicle, i.e. the vehicle must not be on wheels. If the wheel bearing is loaded with the weight of the vehicle when the drive shaft mounting bolt is unscrewed, the inner bearing will be damaged, which will lead to a reduction in its service life. If the vehicle needs to be mounted on wheels or moved, the following must be observed: Install an outer CV joint instead of the drive shaft, Tighten the fastening bolt (use removed) external hinge with a torque of 120 Nm.
Remove wheel. Remove soundproof cover. Remove, if present, the protective shield of the inner hinge. Remove drive shaft bolts -arrows- from gearbox flange.
Remove nuts -arrows-. Detach the wishbone from the ball joint. Remove drive shaft from wheel hub.
Installation
Remove any paint residue and/or rust from the threads/splines of the outer joint. Insert the outer joint into the splines of the wheel hub as far as possible. Screw ball joint to triangular link -arrows-.
Note: Check the ball joint boot for damage and creases.
Install driveshaft inner joint and tighten with new bolts crosswise to 10 Nm.
Note: Use new washers and new screws.
Tighten the Allen screws with the prescribed tightening torque crosswise. Install protective screen (in the presence of). Install soundproof cover. Tighten the bolt securing the drive shaft to the hub.
Note: When doing this, the vehicle must not rest on its wheels, as the wheel bearing will be damaged.
Tighten the wheel bolts.
Tightening torques
Designation / difference of diameters, amount of grease for hinges
Use an appropriate lubricant for the outer joints.
1) On tripod joints, measure distance -A- instead of diameter.
