Axle Lubricant Change (w Differential Cooler)
Draining Procedure
1. Turn ON the ignition, with the engine OFF. For vehicles equipped with Y41 passive keyless entry systems, refer to Keyless Entry System Description and Operation (without ATH) Keyless Entry System (without ATH)Keyless Entry System Description and Operation (with ATH) Keyless Entry System (with ATH).
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.
3. Install a drain pan under the differential.
Note: Disengage the spring retainer (2) from the quick-connect fitting.
4. Disconnect the elbow (3) from the quick-connect fitting (1) in the differential housing.
5. Cap or plug the elbow to prevent dirt or debris from entering the hose.
6. Remove the quick connect fitting (1) from the differential housing.
7. Disengage the banjo fitting and drain plug adaptor (4) from differential drain hole.
8. Drain the fluid from the rear axle.
9. Purge the oil from the differential oil cooler using the following procedure.
1. Secure the quick connect elbow over a drain pan.
2. Insert a temperature switch bypass plug into the differential cooler temperature switch wiring harness connector.
Note: Take care to catch excess fluid in the drain pan.
3. Run the coolant pump for 1 minute.
Note: Replace the differential temperature sensor gasket whenever the sensor is removed.
4. Remove the temperature switch bypass plug from the differential cooler temperature switch wiring harness connector.
Filling Procedure
1. Clean any dirt or debris from around the fill plug opening.
Caution: Refer to Fastener Caution Fastener Caution.
Note: The drain plug adaptor must be oriented to the rear of the vehicle.
2. Connect the banjo fitting and drain plug adaptor (1) to differential drain hole and tighten to 23 Nm (17 lb ft).
3. If the vehicle is equipped with a limited slip differential, first add limited slip lubricant additive to the differential. Refer to Adhesives, Fluids, Lubricants, and Sealers Fluid Type Specifications.
4. Fill the differential with lubricant. Refer to Adhesives, Fluids, Lubricants, and Sealers Fluid Type Specifications.
5. Ensure that the gear lubricant level is even with the bottom of the fill plug hole to no lower than 6 mm (0.25 in) below the opening.
6. Purge the air in the system by the following manner:
1. Secure the quick connect elbow over a drain pan.
2. Insert a temperature switch bypass plug into the differential cooler temperature switch wiring harness connector.
Note: Take care to catch excess fluid in the drain pan.
3. Run the coolant pump until a steady stream of fluid is present.
4. Remove the temperature switch bypass plug from the differential cooler temperature switch wiring harness connector.
5. Secure the quick connect elbow at a level above the fill opening
6. Ensure that the gear lubricant level is even with the bottom of the fill plug hole to no lower than 6 mm (0.25 in) below the opening. Add axle lubricant as needed.
7. Install the quick connect fitting (1) into the differential housing and tighten to 39 Nm (29 lb ft).
8. Connect the elbow (3) to the quick connect fitting (1) in the differential housing.
9. Insert a temperature switch bypass plug into the differential cooler temperature switch wiring harness connector.
10. Run the coolant pump for 1 minute.
11. Check the differential coolant system for leaks.
12. Remove the temperature switch bypass plug from the differential cooler temperature switch wiring harness connector.
13. Repair any leaks as needed.
14. Remove the quick-connect fitting and recheck the fluid level taking care not to spill fluid from the cooler lines.
15. Ensure that the gear lubricant level is even with the bottom of the fill plug hole to no lower than 6 mm (0.25 in) below the opening. Add axle lubricant as needed.
16. Install the quick connect fitting (1) into the differential housing and tighten to 39 Nm (29 lb ft).
7. Lower the vehicle.
8. Turn OFF the ignition.
