8 Clean all parts and check for wear.

Assembly

1 Install thrust washer on front axle shaft gear.

Note
The lubricating groove on the thrust washer should point toward the front axle shaft gear.

2 Install front axle shaft gear in differential housing.

3 Slide differential pinions with spherical washers onto differential spider.

4 Install complete differential spider in cover.

5 Position thrust washer on other front axle shaft gear and install together with differential spider.

Note
The lubrication groove in the thrust washer should point toward the front axle shaft gear.

6 Position differential housing and clamp.

Note
Markings (same numbers) must coincide.

7 Tighten differential housing (90...100 Nm).

8 Check turning torque for differential and adjust (30...50 Nm).

Note
The turning torque can be changed with the thrust washers (front axle shaft gear). The thrust washers are available in thicknesses from 1.30...1.85 mm in increments of 0.05 mm.

10 Heat both tapered roller bearings up to ap-

prox. 80 °C and drive on.

11 The tapered roller bearings should contact the differential housing without play. Check with feeler gauge.
