Note: If the drive shaft mounting bolt is loosened by more than 90°, 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 is to be mounted on wheels or moved, the following must be observed: Install an outer joint instead of the drive shaft. Tighten the mounting bolt (use old) outer CV joint with a torque of 120 Nm.
Unscrewing a dodecagonal bolt
Remove the decorative wheel cap, if the wheel is light-alloy - remove the wheel and push the hub cap out of it (depending on execution). Set wheel (depending on configuration) no cap back. Using socket 24 mm -T10361-, with vehicle on wheels, unscrew bolt -arrow- by max. 90°, otherwise the wheel bearing could be damaged. Raise the vehicle so that the wheels are off. Press the brake pedal (this will require an assistant). Remove hexagon bolt -arrow-.
Installing the hex bolt
Always use only a new bolt.
Note: When tightening the CV joint bolt, the wheels must not touch the floor, otherwise the wheel bearing may be damaged.
Press the brake pedal (this will require an assistant). Tighten hexagon bolt to 200 Nm. Lower vehicle onto wheels. Press the brake pedal (this will require an assistant). Tighten the hex head bolt by 180°. Install trim cap, alloy wheel cap (depending on execution).
