Removing and installing the wheel hub with wheel bearing
Removing and installing the wheel hub with wheel bearing
Removing:
  Note
t  If the screw for securing the drive shaft is loosened more than 90°, the wheel bearings must not be loaded through the weight of the vehicle, i.e the vehicle must not stand on its wheels.
t  If the wheel bearings are loaded through the weight of the vehicle when the bolt for securing the drive shaft is removed, the inner wheel bearing may be damaged. This shortens the life of the wheel bearing.
t  If the vehicle is standing on its wheels or moves, pay attention to the following: Install the outer joint instead of the drive shaft. Tighten the fixing screw (use the one which was previously removed) of the outer joint to the tightening torque of 120 Nm.
–  Unscrew screw for securing the drive shaft to the wheel hub:
t  Hexagon screw → Chapter
t  Twelve-sided bolt → Chapter
–  Remove wheel.
–  Remove brake caliper or brake caliper with brake carrier and tie with wire to the body → Brake systems; Rep. gr.46.
–  Remove ABS speed sensor → Brake systems; Rep. gr.45.
–  Remove brake disc.
–  Push the drive shaft as far as possible out of the wheel hub (in direction of gearbox).
