15. Install the bearing cap for the cluster gear with
a 2.54 mm (0.100 in.) shim pack and the bearing
cup. Install the capscrews for the bearing cap
and tighten them evenly to 1.2 N•m (10 lbf in)
while rotating the gears. Measure the clearance
between the bearing cap and the housing in
three places (near the capscrews). Find the av-
erage of the three measurements. Add 0.15 mm
(0.006 in.) to the average measurement. Sub-
tract this dimension from 2.54 mm (0.100 in.) to
obtain the required shim pack. Install the shims,
O-ring, and bearing cap. Use a thread sealant
on the capscrews and tighten the capscrews to
19 N•m (14 lbf ft).
16. Adjust and install the bearing cap for the pinion
using the procedures described in Step 15.
17. Apply a bead of sealant (Loctite 515 or equiva-
lent) to the flange of the axle housing. Install
the differential housing onto the axle housing.
Tighten the bolts and capscrews that fasten the
two housings together to 38 N•m (28 lbf ft).
18. If removed, install the axle spindles on the axle
housing, Install new O-rings on the axle spindles.
See Figure 15. Install the axle spindle into the
axle housing. Tighten the capscrews to 90 N•m
(66 lbf ft). Lubricate the axle spindles with Never
Seez
®
and slide the mounts on the axle spindles.
