FRONT FINAL DRIVE

1. Install drive pinion rear bearing outer race and drive pinion front

bearing outer race using Tools.

CAUTION:

• First tap the drive pinion bearing outer race until it

becomes flush with the gear carrier.

• Do not reuse drive pinion front and rear bearing outer

race.

2. Select drive pinion height adjusting washer. Refer to 

DLN-212, "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.

4. Install the collapsible spacer to the drive pinion.

CAUTION:

Do not reuse collapsible spacer.

5. Apply differential gear oil to the drive pinion rear bearing, and

install the drive pinion assembly to the gear carrier.

6. 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.

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 

DLN-193, "Disassembly and

Assembly"

.

• 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-212, "Inspection and Adjustment"

.

12. Install the differential case assembly. Refer to 

DLN-193, "Disassembly and Assembly"

.

FRONT FINAL DRIVE

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 

DLN-212, "Inspection

and Adjustment"

.

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 new drive gear bolts.

• Use Genuine High Strength Thread Locking Sealant or equiv-

alent. Refer to 

GI-21, "Recommended Chemical Products and

Sealants"

.

CAUTION:

Make sure the drive gear back and threaded holes are

clean.

9. Tighten the new drive gear bolts to the specified torque. Refer to

DLN-193, "Disassembly and Assembly"

. After tightening the

new drive gear bolts to the specified torque, tighten an additional

34

° to 39° using Tool (A).

CAUTION:

• Always use Tool. Avoid tightening based on visual check

alone.

• Tighten new drive gear bolts in a crisscross pattern.

10. Press the new side bearing inner races to the differential case

using Tools.

CAUTION:

Do not reuse side bearing inner races.

11. Install housing spacer into gear carrier.
12. 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).
