Differential Clutch Oil Replacement

Differential Clutch Oil Replacement

Warning

The hydraulic pressure in the differential clutch is very high. To prevent personal injury, wait for at least 10 minutes before removing any parts from the differential clutch.

Note: The vehicle should be as level as possible when performing this procedure.

1. Raise the vehicle and support the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair)

Caution: It is very important to observe maximum cleanliness when working on the differential clutch. Dirt particles can seriously damage the function and service life of the differential clutch.

3. Remove the differential clutch cover to drain the differential clutch.

Note: DO NOT reuse the old gasket. Replace with NEW only.

4. Install the differential clutch cover.

Caution: Refer to Fastener Caution (Fastener Caution).

5. Install the differential cover bolts and tighten to 6 Nm (53 lb in) in a star pattern and repeat this torque sequence twice to ensure proper sealing around the accumulator and the filter.

Caution: Fluids for the differential clutch and the rear axle are different. The fluids must never be mixed or interchanged or vehicle damage will result.

6. Fill the differential clutch with 350 ml (12 ounces) of the proper differential fluid through the vent hose fitting. Refer to Adhesives, Fluids, Lubricants, and Sealers (Adhesives, Fluids, Lubricants, and Sealers).
7. Install the vent hose and fitting and tighten the fitting to 14 Nm (10 lb ft).

15. The differential clutch fluid should be level with the bottom of the differential clutch cover plug hole. Add fluid if needed.
16. Install the differential clutch cover plug (1) and re-tighten to 14 Nm (10 lb ft).
17. Lower the vehicle.
18. Install the scan tool.
19. With engine running, observe the scan tool Rear Differential Clutch Pump Motor Current parameter. The parameter display should be between 2500-3500 mA when the pump is on. If the parameter is below 2500 mA , recheck the fluid level.
