Preparatory work
Adjusting the parking brake
Loosen the parking brake adjustment. See Adjusting the parking brake Adjustments.
Removal
Removing the drive shaft screw
Remove:
- the rear wheel
- the screw for the drive shaft.
Removing the brake calliper and brake disc
Remove:
- the wheel sensor cable from the retainer on the brake hose
- the brake calliper mounting screws.
Suspend the calliper in a steel wire.
- the brake disc locating pin/screw
- the brake disc
Removing the wheel sensor
Clean the area around the wheel sensor and remove the screw.
Carefully remove the sensor from the wheel spindle.
Bind the sensor so it is well protected.
Removing the spring strut
Remove the spring strut from the control arm.
Note! There is some tension in the spring strut.
Removing the rear wheel hub
Use a mobile jack to raise the wheel suspension until there is approx. 400 mm between the fender edge and the center of the wheel hub to provide the best accessibility to the wheel hub screws. See also fender edge measurement.
Remove:
- the 4 screws
- the rear wheel hub from the wheel spindle and drive shaft.
Note! Make sure that the drive shaft releases from the rear wheel hub. There must be no axial forces on the drive shaft joints.
Cleaning
Checking and cleaning
Clean:
- the drive shaft end, especially if there is rust on the edge. See the illustration.
(The outer seal ring of the wheel hug will lie against this surface).
- the mating faces of the wheel hub in the wheel spindle
- the wheel sensor
- the sensor seat in the wheel spindle so it is absolutely clean
- the wheel sensor. Use a soft brush.
Greasing the seal
Lubricate the wheel bearing sealing lip abutting the drive shaft with a little wheel bearing grease. P/N 1161689.
Brush high pressure grease, P/N 1161246 onto the drive shaft so that the splines on the rear half of the drive shaft pin are filled.
