3. Note the following shim selections (shims are
nominally 1.5 mm thick):
738-268C
A. Cover Side - add value A on the gear case hous-
ing to value B on the gear case cover; then add
1.5 mm. This will give you the proper shim
thickness.
NOTE: When shimming a rear gear case, add
value A to value B.
B. Gear Case Side - install a 1.3-1.4 mm shim and
tighten the bolts to 28 ft-lb. Verify backlash to
be within a range of 0.28-0.38 mm (0.011-0.015
in.) and end-play to be within a range of
0.10-0.20 mm (0.004-0.008 in.). If not within
specification range, reselect shim until backlash
specification range can be verified.
4. Prior to final assembling, apply molybdenum dis-
ulfide grease to all oil seal lips.
5. Prior to final assembling, prelubricate journal on
pinion assembly with SAE 80W-90 hypoid gear
lubricant prior to pressing assembly into gear case
housing.
Assembling Pinion Gear
1. Install the bearing onto the pinion shaft. Install the
pinion shaft collar.

2. Place the pinion assembly in a bearing puller; then
install the bearing using a press.

3. Install the pinion gear assembly into the housing.
Using the 48 mm Internal Hex Socket, secure the
pinion gear assembly with the existing lock collar.
Tighten to 125 ft-lb.
NOTE: On a front differential, the lock collar has
right-hand threads. On a rear gear case, the lock
collar has left-hand threads.
