These joints are not serviced separately. If they are defective, the entire shaft must be replaced.
Removal & Installation
Before servicing the vehicle, refer to the Precautions section.
NOTEThis 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. Halfshaft inner and outer boots are not serviceable separately. Boot replacement requires entire shaft assembly replacement.
WARNINGUnequal-length halfshafts are used. The left halfshaft is shorter than the right, and it is necessary to identify and tag halfshafts upon removal to ensure proper installation.
- With vehicle in neutral, position and raise vehicle on hoist.
- Using 14mm hex, remove axle drain plug and drain rear axle fluid into container suitable for fluid reuse.
Install drain plug and torque to:
198 Axle: 44 ft. lbs. (60 Nm).
- Remove rear exhaust system on V8-equipped models.
- Remove wheel/tire assembly from sides that shaft is to be removed.
- Remove wheel hub nut and discard.
- Apply alignment index marks to the propeller shaft rubber coupler and axle flange.
- Remove three propeller shaft coupler-to-axle flange bolt/nuts.
- Using suitable screwdriver, partially disengage halfshaft(s) from axle assembly.
- If a drive-on hoist is used, position transmission jack to rear axle assembly. If a drive-on hoist is not used, compress rear suspension using screw-style under-hoist jack stands, then position transmission jack to rear axle assembly.
Remove rear axle forward mount isolator bolt/nut.
NOTEAccess to rear axle-to-crossmember bolts is best achieved by use of short socket and a flexible-head ratchet.
- Remove two rear axle-to-crossmember bolts.
- Carefully lower the rear axle. While lowering axle, separate propeller shaft from axle and support with suitable rope or wire.
- Lower the axle just enough to remove halfshafts one at a time. Shift axle assembly in one direction, compressing one halfshaft while removing the other. Use caution to protect axle seal and journal.
- Install new axle seals using the seal driver tool 9223 or equivalent.
- Install halfshaft isolation washer. Washer is bi-directional, and can be installed in either direction.
- Install halfshaft to wheel hub/knuckle assembly. Install new hub nut by hand.
- Inspect slinger(s) for handling damage. Straighten as necessary to avoid contact with axle seal.
- Lubricate halfshaft inner joint bearing journal with Mopar® gear and axle lubricant (75W-140). Using new circlip(s), install halfshaft to rear axle assembly. Use care not to damage axle seals. Verify proper installation by pulling outward on joint by hand.
- Raise rear axle assembly into position. Align propeller shaft index marks (3) and start propeller shaft coupler-to-axle bolt/nuts by hand.
- Install two rear axle-to-crossmember bolts and torque to162 ft. lbs. (220 Nm).
- Install rear axle front mount isolator as shown and torque bolt/nut to 48 ft. lbs. (65 Nm).
- Again verify halfshaft inner joints are fully engaged to axle assembly.
- Remove the transmission jack.
- If used, remove screw-type under-hoist jack stands (2).
- Torque the propeller shaft coupler-to-axle flange bolt/nuts to 43 ft. lbs. (58 Nm).
Using a 14mm hex, remove rear axle fill plug . Fill axle with Mopar®75W-140 synthetic gear and axle lubricant in the following quantities:
198 Axle: 1.5 qts. (1.4L)
Install and torque fill plug to:
198 Axle: 44 ft. lbs. (60 Nm).
- For V8 models install exhaust system. Tighten band clamps to 45 ft. lbs. (61 Nm).
- Lower the vehicle. Tighten halfshaft hub nut to 157 ft. lbs. (213 Nm) and install wheel center cap.
- Install wheel/tire assembly and torque lug nuts to 110 ft. lbs. (150 Nm).
