 (2S1330), 

DLN-163, "Removal

and Installation"

 (3S1330) or 

DLN-173, "Removal and Installation"

.

NOTE:
Record the total preload torque measurement.

4.

Remove the drive pinion lock nut using suitable tool.

5.

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.

FRONT OIL SEAL

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 and differential

gear oil to the circumference of the new front oil seal.

2.

Install oil seal/dust shield.

3.

Install the companion flange to the drive pinion while aligning the matching marks.

4.

Apply anti-corrosive oil to the threads of the drive pinion and the
seating surface of the new drive pinion lock nut and new drive
pinion lock nut washer. Then adjust the drive pinion lock nut
tightening torque using suitable tool A, and check the total pre-
load 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 or drive pinion lock nut

washer.

• 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-255, "Dis-

assembly 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-255, "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.

5.

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

CAUTION:

Check the differential gear oil level after installation. Refer to 

DLN-250, "Checking Differential Gear

Oil"

.
