FRONT FINAL DRIVE
1. Install drive pinion rear bearing outer race using Tools.
2. Install drive pinion front bearing outer race using Tools.
3. Select drive pinion height adjusting washer.
4. 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:
Do not reuse drive pinion rear bearing inner race.
5. Install the collapsible spacer to the drive pinion.
CAUTION:
Do not reuse collapsible spacer.
6. Apply differential gear oil to the drive pinion rear bearing, and
install the drive pinion assembly to the gear carrier.
7. Apply differential gear oil to the drive pinion front bearing, and
install the drive pinion front bearing inner race to the drive pinion
assembly.
CAUTION:
Do not reuse drive pinion front bearing inner race.
8. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly 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 of the new front oil
seal.

9. Install the companion flange to the drive pinion while aligning the
matching marks. Tap the companion flange until fully seated
using suitable tool.
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
.
• 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, rota-
tion malfunction, and other malfunctions.
11. Check companion flange runout.
12. Install the differential case assembly.
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.
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.
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. Install and tighten the new drive gear bolts to the specified
DLN-169, "Disassembly and Assembly"
.
CAUTION:
• Make sure the drive gear back and threaded holes are
clean.
• Do not reuse drive gear bolts.
• Tighten new drive gear bolts in a crisscross pattern.

9. Press the new side bearing inner races to the differential case
using Tools.
CAUTION:
Do not reuse side bearing inner races.
10. Install side bearing adjusters into gear carrier.
11. Apply differential gear oil to the side bearings, and install the dif-
ferential case assembly with the side bearing outer races into
the gear carrier.
CAUTION:
Do not reuse side bearing outer race when replacing side
bearing inner race (replace as a set).
12. Install the side bearing caps with the matching marks aligned.
NOTE:
Do not tighten at this step. This allows further tightening of side
bearing adjusters.
13. Tighten each side bearing adjuster alternately turning drive gear.
14. Check and adjust tooth contact, backlash, drive gear runout and total preload torque.
Recheck above items.
