Assembly
1. Inspect the differential parts for damage before as-
sembling.
A. If any bearings are damaged they must be re-
placed with new ones.
B. Check the ring, pinion, and spur gear for abnor-
mal wear and damage; replace worn components.
C. Inspect the housings for cracks and external
damage that could affect the operation of the axle as-
sembly.
D. Inspect the differential case for wear in the side
gear and pinion mate area. Replace the case if its
machined areas are scored or if the pinion mate shaft
fits loosely in the bore.
2. Press the pinion inner bearing onto the pinion drive
gear. Support the bearing on the inner cup of the bearing
ONLY WHEN INSTALLING (Fig. 38).
3. Put the front housing on a press. Using a press plate,
push the pinion outer bearing cup into the housing until
it bottoms in the housing (Fig. 39).
