8. Install the outer bearing spacer with the chamfer to-
wards the pinion splines and position the new outer
bearing cone on the pinion shaft (Fig. 43).
9. With a hollow press sleeve of proper diameter, press
on the outer bearing cone race until the drive pinion
seats in the carrier and a slight drag is felt when the gear
is rotated by hand (Fig. 44). If more than 2 to 13 in-lb (.2
to 1.5 N−m) torque is required to rotate the pinion and
spur gear, tap the pinion shaft with a soft mallet until the
drag is reduced.
10.Apply Permatex No. 2 (or equivalent) to outer diame-
ter of seal, external splines of pinion shaft and internal
splines of pinion coupler. Install differential gear holder
to carrier to retain spur gear (see Special Tools).
11. Install seal into housing. Install shim, flange coupler,
washer and nut onto end of the pinion shaft (Fig. 45).
Torque nut securing pinion coupler from 70 to 90 ft-lbs
(95 to 122 N−m).
12.Check pinion shaft end play.
PINION SHAFT END PLAY:
0.000 to 0.005 in. (0.00 to 0.13 mm)
If end play is incorrect, remove nut, washer and flange
coupler. Replace shim with appropriate thicker or thin-
ner shim and reassemble. Make sure that pinion shaft
end play is correct before continuing with assembly pro-
cedure.
NOTE: Pinion shaft shims are available in 0.094 in.
(2.39 mm) to 0.120 in. (3.05 mm) thickness, and in
0.125 in. (3.18 mm) to 0.151 in. (3.84 mm) thickness in
0.002 (0.05 mm) increments.
13.Remove differential gear holder from carrier.
