Note: If the drive shaft mounting bolt is loosened more than 90°, the wheel bearing must not be loaded with the weight of the vehicle, i.e. the vehicle must not be standing on the wheels. If the wheel bearing is loaded with the weight of the vehicle when the drive shaft mounting bolt is loosened, the inner bearing will be damaged, which will reduce its service life. If the vehicle must be mounted on the wheels or moved, the following must be observed: Install the outer joint instead of the cardan shaft. Tighten the mounting bolt (use old) outer CV joint with a torque of 120 Nm.
Unscrewing a twelve-sided bolt
Remove the decorative wheel cap; if the wheel is alloy, remove the wheel and push the hub cap out of it (depending on the design). Install the wheel (depending on the configuration) without the cap back. With the 24 mm "T10361" nozzle on the car standing on the wheels, unscrew the bolt "arrow" max., by 90°, otherwise the wheel bearing may be damaged. Raise the car so that the wheels are suspended. Press the brake pedal (you will need an assistant for this). Unscrew the twelve-sided "arrow" head bolt.

Installing a twelve-point head bolt
Always use a new bolt.
Note: When tightening the CV joint mounting bolt, the wheels must not touch the floor, otherwise the wheel bearing may be damaged.

Press the brake pedal (you will need an assistant for this). Tighten the twelve-point head bolt to 200 Nm. Lower the car onto its wheels. Press the brake pedal (you will need an assistant for this). Tighten the twelve-sided head bolt by 180°. Install the decorative cap, alloy wheel cap (depending on the design).
