MAJOR REPAIR OPERATIONS
DISASSEMBLY
Mount the' axle housing in the
holding fixture tool 4005 (Fig. 3,
Part 4-1), and perform the "Inspec-
tion Before Disassembly of Carrier"
as explained in Part 4-1, Section 3.
Then
disa~semble
the carrier as out-
lined in the following procedures.
REMOVAL OF
DIFFERENTIAL CASE,
PINION, AND BEARINGS
1. Remove the attaching bolts and
the differential side bearing caps
(Fig. 15). Note the identification
marks stamped on the bearings and
housing for proper assembly.
2. Install the carrier spreader so
that the dowels on the tool enter

4. Remove the spreader tool, and
turn the housing in the holding fix-
ture so that the drive pinion shaft
is in a vertical position. Remove
the nut from the pinion shaft as
shown in Fig. 17.
5. Remove the U-joint flange from
the pinion shaft using the modified
tool shown in Fig. 8.
6. Turn the housing in the hold-
ing fixture so that the drive pinion
is in a horizontal position, and then
remove the pinion shaft oil seal with
the tool shown in Fig. 9. Lift out
the gasket and slinger.
7. Turn tool 4201 onto the pinion
shaft threads and drive against the
tool until the pinion shaft and rear
bearing are loosened from the hous-
ing (Fig. 18). Remove the tool from
the pinion shaft, withdraw the pin-
ion and rear bearing assembly from
the rear of the housing, and remove
the front bearing and preload shims
from the front of the housing. Tie
