DIFFERENTIAL GEAR OIL LEAKAGE AND LEVEL

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 sealant applied on the threads to the

rear final drive assembly. Tighten filler plug to the specified

torque. Refer to

DLN-197, "Disassembly and Assembly"

• Use High Performance Thread Sealant or equivalent. Refer to

Changing Differential Gear Oil

INFOID:0000000009886090

DRAINING

1. Stop engine.
2. Remove the drain plug from the rear final drive assembly to

drain the differential gear oil.

3. Install the drain plug with sealant applied on the threads to the

rear final drive assembly. Tighten drain plug to the specified

torque. Refer to

DLN-197, "Disassembly and Assembly"

• Use High Performance Thread Sealant or equivalent. Refer to

FILLING

1. Remove the filler plug from the rear final drive assembly.
2. Fill the rear final drive assembly with new differential gear oil

until the level reaches the specified level near the filler plug hole.

3. Install the filler plug with sealant applied on the threads to the

rear final drive assembly. Tighten filler plug to the specified

torque. Refer to

DLN-197, "Disassembly and Assembly"

• Use High Performance Thread Sealant or equivalent. Refer to

GI-21, "Recommended Chemical Prod-

ucts and Sealants"

NOTE:

Record the total preload torque measurement.

4. Remove the drive pinion 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 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-197, "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-197, "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
