Differential Assembly: Service and Repair

Axle Assembly













Removal

1. Remove the driveshaft assembly. For additional information, refer to Drive/Propeller Shafts, Bearings and Joints.

2. Remove the rear halfshafts. For additional information, refer to Drive Axles, Bearings and Joints.

3. Remove the stabilizer bar. For additional information, refer to Rear Suspension.

4. Position a suitable transmission hydraulic jack to the axle housing.
- Securely strap the jack to the housing.

5. Remove the 4 differential housing-to-front insulator bracket bolts.

6. Remove the 6 side insulator bracket-to-rear axle differential bolts.

7. Lower the axle to gain clearance to the Active Torque Coupling (ATC) electrical connector and disconnect the connector.

8. Remove the axle assembly.

Installation

1. NOTICE: If replacing the axle assembly, the 4X4 control module will need to be reconfigured with the new Active Torque Coupling (ATC) bar code information. If the new bar code information does not match the existing 4X4 control module information, driveline damage or driveability concerns can occur.

NOTE: The ATC bar code can be found etched on the ATC wire harness connector of the new axle assembly.

Record the bar code identification number from the new axle assemblies wire harness connector.





2. Position the axle housing on a suitable transmission hydraulic jack.
- Securely strap the jack to the housing.

3. Raise the axle and connect the ATC electrical connector.

4. Install the 6 side insulator bracket-to-rear axle differential bolts.
- Tighten to 90 Nm (66 lb-ft).

5. Install the 4 differential housing-to-front insulator bracket bolts.
- Tighten to 90 Nm (66 lb-ft).

6. Install the stabilizer bar. For additional information, refer to Rear Suspension.

7. Install the rear halfshafts. For additional information, refer to Drive Axles, Bearings and Joints.

8. Install the driveshaft assembly. For additional information, refer to Drive/Propeller Shafts, Bearings and Joints.

9. Using the scan tool, program the 4-digit bar code information retrieved from the new axle assembly harness connector into the 4X4 control module using the ATC Bar Code Entry service function.
- The scan tool will verify that the numbers entered are valid and display a message if the information is not correct.
