1. Make sure that differential gear oil is not leaking from the rear final drive assembly or around it.
2. Check the differential gear oil level from the filler plug hole as

shown.

CAUTION:

Do not start engine while checking differential gear oil level.

3. Install the filler plug with a new gasket on it to the rear final drive

assembly. Tighten to the specified torque. Refer to

DLN-426,

"Disassembly and Assembly"

CAUTION:

Do not reuse gasket.

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.

FRONT OIL SEAL

1. 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 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 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-426, "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-426, "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-416, "Checking Differential Gear

Oil"

SIDE OIL SEAL

Removal and Installation

INFOID:0000000005258505

REMOVAL

1. Remove the rear wheel sensor. Refer to

BRC-125, "Removal and Installation"

2. Remove the drive shaft from the rear final drive assembly. Refer to

RAX-8, "Removal and Installation"

3. Remove the side flange using Tools.

NOTE:

Circular clip installation position: Rear final drive side

4. Remove the side oil seal using suitable tool.

CAUTION:

Do not to damage gear carrier.

INSTALLATION

1. Apply multi-purpose grease to the lips and differential gear oil to

the circumference of the new side oil seal. Then drive the new

side oil seal in evenly until it becomes flush with the gear carrier

using Tool.

CAUTION:

• Do not reuse side oil seal.

• Do not incline the new side oil seal when installing.

• Apply multi-purpose grease to the lips and differential

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

2. Install the side flange using Tool.
a. Install the Tool to the side oil seal as shown.

b. Insert the side flange until the serrated part of the side flange

has engaged the serrated part of the side gear and remove the

Tool.

c. Drive in the side flange using suitable tool.

NOTE:

Installation is completed when the driving sound of the side

flange turns into a sound which seems to affect the whole rear

final drive assembly.

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