8. Remove the front oil seal using Tool as shown.

INSTALLATION

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

Then drive the new front oil seal in evenly to 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

DLN-390, "Disassembly and

Assembly"

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

torque or the total preload torque exceeds the specifications, replace the collapsible spacer and

tighten it again to adjust. Refer to

DLN-390, "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
