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 a new 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, 60 in-lb) increments until the total

preload 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-261, "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-261, "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, "Changing Differential Gear

Oil"

.

REMOVAL

1. Drain the differential gear oil. Refer to 

DLN-250, "Changing Differential Gear Oil"

.

2. Disconnect the parking brake cable (A) and brake tube (B) from

the carrier cover.

3. Remove the carrier cover bolts and separate the carrier cover

from the gear carrier using Tool.

CAUTION:

• Do not damage the mating surface.

• Do not insert flat-bladed screwdriver, this will damage the

mating surface.

INSTALLATION

1. Apply a bead of sealant to the mating surface of the carrier

cover as shown.

• Use Genuine Silicone RTV or equivalent. Refer to 

GI-21,

"Recommended Chemical Products and Sealants"

.

CAUTION:

Remove any old sealant adhering to the mating surfaces.

Also remove any moisture, oil, or foreign material adhering

to the application and mating surfaces.

2. Install the carrier cover to the gear carrier. Tighten the bolts to

the specified torque. Refer to 

DLN-261, "Disassembly and

Assembly"

.

3. Connect the parking brake cable and brake tube to the carrier

cover.

4. Fill the rear final drive assembly with recommended differential gear oil. Refer to 

DLN-250, "Changing Dif-

ferential Gear Oil"
