Assembly (Fig. 21)
1. Inspect the differential parts for damage before as-
sembling.
A. If any bearings are damaged they must be re-
placed with new ones. Replace all removed bear-
ings.
B. Check the ring, pinion and spur gear for abnormal
wear or 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 new pinion inner bearing cone onto the pinion
drive gear. Support the bearing on the inner cup of the
bearing ONLY WHEN INSTALLING (Fig. 37).

push new pinion outer bearing cup into the housing until
it bottoms in the housing (Fig. 38).
