11. Correct the drive pinion height adjusting washer size by referring
to the drive pinion “head number”.
There are two numbers painted on the drive pinion. The first
one refers to the drive pinion and drive gear as a matched
set. This number should be the same as the number on the
drive gear. The second number is the drive pinion “head
number”. It refers to the ideal drive pinion height from stan-
dard for quietest operation. Use the following chart to
determine the correct drive pinion height adjusting washer.
12. Select the correct drive pinion height adjusting washer. Refer to
DLN-377, "Inspection and Adjustment"
13. Remove the Tool from the gear carrier and disassemble to
retrieve the drive pinion bearings.

• Do not reuse drive pinion front and rear bearing outer
race.
2. Select drive pinion height adjusting washer. Refer to
DLN-377, "Inspection and Adjustment"
.
3. Install the selected drive pinion height adjusting washer to the

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.
4. Install the collapsible spacer to the drive pinion.
CAUTION:

7. Press the drive pinion front bearing inner race to the drive pinion
as far as drive pinion lock nut can be tightened using Tool.
8. Apply multi-purpose grease to the lips and differential gear oil to
the circumference of the new front oil seal. Then drive the new
front oil seal in evenly until it becomes flush with the gear carrier
using Tools.
CAUTION:
• Do not reuse front oil seal.
• Do not incline the new front oil seal when installing.
• Apply multi-purpose grease to the lips and differential
gear oil to the circumference of the new front oil seal.
9. Install the companion flange to the drive pinion while aligning the matching marks.
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-377, "Inspection and Adjustment"
.
12. Install the differential case 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.
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. Install the pinion mate shaft and align the lock pin hole on the
pinion mate shaft with the lock pin hole on the differential case.
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.
