Removal and Installation
REMOVALNOTE: This procedure requires the compression of the rear suspension to ride height. A drive-on hoist should be used. If a drive-on hoist is not used, screw-style under-hoist jack stands are required to compress the rear suspension, facilitating rear halfshaft removal.
CAUTION: Never grasp halfshaft assembly by the inner or outer boots. Doing so may cause the boot to pucker or crease, reducing the service life of the boot and joint. Avoid over angulating or stroking the C/V joints when handling the halfshaft.
1. With vehicle in neutral, position and raise vehicle on hoist.
2. Using 14mm hex, remove axle drain plug (1) and drain rear axle fluid into container suitable for fluid reuse.
3. Install drain plug (1) and torque to 50 Nm (37 ft. lbs.) torque.
4. Remove rear exhaust system (2) on dual-outlet exhaust models, otherwise, lower exhaust system at rear hanger(s).
5. Apply alignment index marks (3) to the propeller shaft rubber coupler (1) and axle flange (2).
6. Remove three (3) propeller shaft coupler-to-axle flange bolt/nuts.
7. Using suitable screwdriver (1), partially disengage halfshaft(s) (2) from axle assembly.
8. If a drive-on hoist is used, position transmission jack(1) to rear axle assembly If a drive-on hoist is not used, compress rear suspension using screw-style under-hoist jack stands (2), then position transmission jack to rear axle assembly
9. Remove rear axle forward mount isolator (1) bolt/nut (2).
10. Remove two rear axle-to-crossmember bolts (1).
11. Carefully lower rear axle. While lowering axle, separate propeller shaft from axle and support with suitable rope or wire (1).
12. Lower axle just enough to remove both halfshafts one at a time. Shift axle assembly in one direction, compressing one halfshaft while removing the other (1). Use caution to protect axle seal and journal.
13. Remove axle assembly from vehicle and transfer to bench.
14. Using suitable screwdriver, remove axle seals and discard.
INSTALLATION
1. Install new axle seal(s) (1) using Tool 9755 (2).
NOTE: Use care when installing halfshaft to axle assembly. The halfshaft installation angle should be minimized to avoid damage to seal upon installation.
2. Using new circlip(s), install halfshaft (1) to rear axle assembly. Use care not to damage axle seals(2). Verify proper installation by pulling outward on joint by hand.
3. Raise rear axle assembly into position. Align propeller shaft index marks (3) and start propeller shaft coupler-to-axle bolt/nuts by hand.
4. Install two rear axle-to-crossmember bolts (1) and torque to 220 Nm (162 ft. lbs.).
5. Install rear axle front mount isolator (1) as shown and torque bolt/nut to 65 Nm (48 ft. lbs.).
6. Again verify halfshaft inner joints are fully engaged to axle assembly
7. Remove transmission jack (1).
8. If used, remove screw-type under-hoist jack stands (2).
9. Torque propeller shaft coupler-to-axle flange bolt/ nuts to 58 Nm (43 ft. lbs.).
10. Using a 14mm hex, remove rear axle fill plug (1). Fill axle with 1.2L (1.3 qts.) of Mopar 75W-140 Synthetic Gear & Axle Lubricant. Install fill plug and torque to 50 Nm (37 ft. lbs.).
