The differential box position and the lateral clearance in the gear engagement are set using compensation washers. If damaged, replace the ring.
Remove the differential box as a complete unit.
Remove the pinion drive shaft flange protective plate.
Measure the turning resistance force using a special device.
The measured force (20 Nm) must be achieved during installation, but not exceeded.
While holding the drive shaft flange with a wrench, unscrew the flange nut.
Remove the flange with a puller.
Remove the oil seal.
Coat the new seal with oil and press it in.
Press the new flange onto the drive shaft using the tool, but do not tighten.
Note: When replacing the drive shaft flange, the spacer sleeve does not need to be replaced.
Tighten the tapered bearing to the previously measured torque +20 Nm.
If the turning resistance force is exceeded, the spacer sleeve must be replaced.
