NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

REMOVAL

1. Remove the drive shafts from the rear final drive assembly and support them using suitable wire. Refer to

RAX-8, "Removal and Installation"

.

2. Remove the side flanges and side oil seals. Refer to 

DLN-460, "Removal and Installation"

.

3. Remove the rear propeller shaft. Refer to 

DLN-340, "Removal and Installation"

.

4. Measure the total preload torque. Refer to 

DLN-483, "Inspection and Adjustment"

.

NOTE:

Record the total preload torque measurement.

5. Remove the drive pinion lock nut using suitable tool.
6. Put matching marks on the companion flange and drive pinion

using paint.

CAUTION:

Use paint to make the matching marks. Do not damage the

companion flange or drive pinion.

7. Remove the companion flange using suitable tool.

1. Apply multi-purpose grease to the lips of the new front oil seal.

Then drive the new front oil seal in evenly until it becomes flush

with the gear carrier using Tool.

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.

2. Install the companion flange to the drive pinion while aligning the matching marks.
3. 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 total preload torque using Tool (B).

• The total preload torque should be within the total preload

torque specification. When not replacing the collapsible

spacer, it should also be equal to the measurement taken dur-

ing removal plus an additional 0.56 N·m (0.06 Kg-m, 5 in-lb).

• If the total preload torque is low, tighten the drive pinion lock

nut in 6.8 N·m (0.69 Kg-m, 5ft-lb) increments until the total pre-

load torque is met.

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-467, "Disassembly and

Assembly"

.

• Do not loosen drive pinion lock nut to adjust the total preload torque. If the total preload torque

exceeds the specifications, replace the collapsible spacer and tighten it again to adjust. Refer to

DLN-467, "Disassembly and Assembly"

.

• After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rota-

tion malfunction, and other malfunctions.

4. Installation of the remaining components is in the reverse order of removal.

CAUTION:

Check the differential gear oil level after installation. Refer to 

DLN-457, "Checking Differential Gear

Oil"

.
