Removing and installing a drive shaft with CV joint
Removing and installing a drive shaft with CV joint
Removing:
–  Remove screw for securing the drive shaft to the wheel hub → Chapter.
  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.
–  Remove wheel.
–  Remove the sound dampening system → Body Work; Rep. gr.50.
–  Remove drive shaft screening from the engine (if present).
–  Unscrew the drive shaft from the flange/gearbox.
–  Mark the opposite position of the track control arm/steering joint.
   
–  Unscrew the nuts -arrows-.
–  Pull the wheel-bearing housing with steering joint out of the track control arm.
–  Pull the drive shaft out of the wheel hub.
Installing:
Remove possible paint and/or corrosion residue from the thread/the serration of the outer joint
–  Insert outer joint as far as possible into the serration of the wheel hub.

–  Screw steering joint to the track control arm -arrows-.
  Note
t  Make sure the boot is neither damaged nor twisted.
t  Use new washers and new screws.
–  Position the inner joint of the drive shaft and tighten new screws to 10 Nm crosswise.
–  Tighten the screws with internal serrations crosswise according to the specified torque.
–  Attach drive shaft screening to the engine (if present).
–  Install the noise insulation → Body Work; Rep. gr.50.
–  Tighten screw for securing the drive shaft to the wheel hub → Chapter.
  Note
When tightening the screw for attaching the drive shaft, the wheel must be raised until it is fully off the ground, otherwise the wheel bearing can be initially damaged.
–  Tighten wheel.
