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 stand on the 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.
Remove wheel. Remove the bracket with the brake caliper and tie it with wire to the body. Remove the speed sensor for the ABS system. Remove brake disc. On vehicles with automatic headlight range control, unscrew nut -1- for front left vehicle level sender -G78-. Unscrew securing nuts -arrows-. Press ball joint out of wishbone. Push the drive shaft out of the hub and secure, e.g. tie it with wire to the body. Screw the ball joint back onto the triangular link. Remove bolts -arrows-. Remove wheel bearing from steering knuckle.
Carefully! Avoid contamination and damage to the seal during work and storage.
Bearing -1- must be stored facing upwards. Always place hub with bearing on hub -2-.
Do not grab the bearing by the inner race. Remove the bearing from the packaging, always placing it on the outside.
Installation
Installation in reverse order. Tighten the bolt securing the drive shaft to the hub. After replacing the steering knuckle, it is necessary to adjust the wheel alignment angles.
