7. If the pulling force is outside the specification, use a thicker or
thinner side bearing adjusting washer to adjust. Refer to
483, "Inspection and Adjustment"
.
CAUTION:
Select a side bearing adjusting washer for right and left

8. Record the total amount of washer thickness required for the correct side bearing preload torque.
ASSEMBLY
Drive Pinion Assembly
1. Install the drive pinion front and rear bearing outer races using
Tools.
CAUTION:
Do not reuse drive pinion front and rear bearing outer race.
2. Select a drive pinion height adjusting washer. Refer to
DLN-483, "Inspection and Adjustment"
.
3. Install the selected drive pinion height adjusting washer to the
drive pinion. Press the drive pinion rear bearing inner race to it
using Tool.
CAUTION:
• Install the drive pinion height adjusting washer in the
proper direction as shown.
• Do not reuse drive pinion rear bearing inner race.
If the pulling force is less than the specification:

10. Apply anti-corrosive oil to the threads of the drive pinion and the
seating surface of the new drive pinion lock nut. Then adjust the
drive pinion lock nut tightening torque using suitable tool (A),
and check the drive pinion bearing preload torque using Tool
(B).
CAUTION:
• Do not reuse drive pinion lock nut.
• Apply anti-corrosive oil to the threads of the drive pinion
and the seating surface of the new drive pinion lock nut.
• Adjust the drive pinion lock nut tightening torque to the
lower limit first. Do not exceed the drive pinion lock nut
specified torque. Refer to
.
• If the drive pinion bearing preload torque exceeds the
specified value, replace collapsible spacer and tighten it
again to adjust. Do not loosen drive pinion lock nut to
adjust the drive pinion bearing preload torque.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
11. Check companion flange runout. Refer to
DLN-483, "Inspection and Adjustment"
.
12. Install the differential case assembly. Refer to
Differential Assembly
1. Install side gear thrust washers with the same thickness as the
ones installed prior to disassembly, or reinstall the old ones on
the side gears.
2. Install the side gears and side gear thrust washers into the dif-
ferential case.
CAUTION:
Make sure that the circular clip is installed to side gears.
3. Install the pinion mate thrust washers to the two pinion mate
gears. Then install the pinion mate gears with the pinion mate
thrust washers by aligning them in diagonally opposite positions
and rotating them into the differential case.

4. Align the lock pin hole on the differential case with the lock pin
hole on the pinion mate shaft, and install the pinion mate shaft.
5. Measure the side gear end play. If necessary, select the appro-
priate side gear thrust washers. Refer to
6. Drive a new lock pin into the pinion mate shaft until it is flush
with the differential case using suitable tool.
CAUTION:
Do not reuse lock pin.
7. Align the matching mark of the differential case with the mark of
the drive gear, then place the drive gear onto the differential
case.
8. Apply thread locking sealant into the threaded holes of the drive
gear and install the bolts.
• Use Genuine Medium Strength Thread Locking Sealant or
equivalent. Refer to
GI-14, "Recommended Chemical Prod-
CAUTION:
Make sure the drive gear back and threaded holes are
clean.
9. Tighten the drive gear bolts to the specified torque. Refer to
. After tightening the drive gear bolts
to the specified torque, tighten an additional 34
°
using Tool.
CAUTION:
• Always use Tool. Avoid tightening based on visual check
alone.
• Tighten drive gear bolts in a crisscross pattern.
