Carry out the following work:
Removal:
–  Loosen drive shaft bolt at wheel hub → Chapter.
  Caution
Wheel bearings must not be subjected to load after loosening bolt securing drive shaft at wheel hub.
If they have to support the weight of the vehicle they will be damages and their service life will be reduced.
It is not permissible to turn drive shaft bolt more than 90° anti-clockwise if vehicle is standing on its wheels.
Do not attempt to move the vehicle without the drive shafts fitted; this would result in wheel bearing damage. If it is necessary for a vehicle to be moved, please comply with the following instructions:
t  Install an outer joint instead of the drive shaft.
t  Tighten the outer joint to 120 Nm.
–  Loosen wheel bolts.
–  Raise the vehicle.
–  Remove wheel.
   
–  Unscrew nut -arrow- and pull coupling rod -1- off suspension strut.

–  Pull wheel bearing housing with swivel joint out of suspension link.
–  Pull outer joint of drive shaft out of wheel hub.
–  Secure drive shaft to body with wire.
  Caution
Do not let the drive shaft hang down under its own weight, as otherwise excessive bending could damage the inner CV joint.
–  Bolt swivel joint to suspension link again.
