o f lesser quality or substitute deskn. Torque values
must be used as specified during reassembly to
assure proper retention o f this part.

I. Raise rear of car and support securely under rear of
frame.
2. Loosen parking brake cables so that brake is not
applied when axle assembly is lowered.
3. Mark rear universal joint and pinion flange for proper
alignment at reassembly. Disconnect rear universal joint. On
H Series cars it will be necessary to disconnect upper control
arm at differential end.
4. Lower differential carrier assembly just far enough to
clear lower portion of fuel tank.
The following steps also apply when making repairs with
differential assembly removed from car.
5. Remove bolts securing cover to housing to drain
lubrciant.
6. While lubricant is draining, remove rear wheels and
drums.
7. Remove rear axle shafts
Before proceeding with following steps, it is advisable to
check the existing ring gear to pinion backlash (Fig. 48-22),
This will indicate gear or bearing wear or an error in backlash
or pre-load setting which will help in determining cause of
axle noise. Backlash should be recorded so that if same gears
are reused, they may be reinstalled at original lash to avoid
changing gear tooth contact.
8. Mark side bearing caps for proper installation at
reassembly. Remove bolts holding differential side bearing
caps to housing.

1. If differential side bearings are to be replaced, insert
Remover Adapter J 8 107-2 or J 23598 in center hole and pull
bearing using Puller J 22888 (Fig. 4B-24).
2. Remove bolt that retains differential pinion shaft (Fig.
4B-25). Remove differential pinions, side gears and thrust
washers from case.
3. If ring gear is to be replaced and it is tight on case
after removing bolts, tap it off using a soft hammer; do not
pry between ring gear and case.
