3. Remove the stabilizer bar. REFER to Stabilizer Bar .

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 ATC (Active Torque Coupling) electrical connector and disconnect the connector.

8. Remove the axle assembly.

Installation

1. NOTICE: If replacing the axle assembly, reconfigure the 4WD (Four-Wheel Drive) control module with the new ATC (Active Torque Coupling) bar code information. If the new bar code information does not match the existing 4WD (Four-Wheel Drive) control module information, driveline damage or driveability concerns can occur.

NOTE: The ATC (Active Torque Coupling) bar code can be found etched on the ATC (Active Torque Coupling) wire harness connector of the new axle assembly.
Record the ATC (Active Torque Coupling) 4-digit bar code identification number.






2. Position the axle housing on a suitable transmission hydraulic jack.

- Securely strap the transmission hydraulic jack to the axle housing.


3. Raise the axle and connect the ATC (Active Torque Coupling) 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. REFER to Stabilizer Bar .

7. Install the rear halfshafts. REFER to Halfshaft .

8. Install the driveshaft assembly. REFER to Driveshaft .

9. Using the scan tool, program the 4-digit bar code information retrieved from the new axle assembly harness connector into the 4WD (Four-Wheel Drive) control module using the ATC (Active Torque Coupling) Bar Code Entry service function.

- The scan tool verifies the numbers entered are valid and displays a message if the information is not correct.
