Use a drive-on hoist or rear jack stands to compress the rear suspension so that the screws can be removed from the rear halfshaft-then you can repair and service the axle shaft assembly. If the boots inside the halfshaft need service, the entire shaft has to be taken out and replaced. It is very important to assign the unequal halfshafts so that the left halfshaft is labeled as the shorter one. Do not touch the halfshaft assembly by its boots to stop any possible damage. With the drain plug (1) close to the wheel, put the vehicle in neutral, raise it and then remove it with a 14mm wrench to empty the rear axle fluid. Put back the drain plug (1) and tighten it up to 60 Nm if you have the 198 axle or 50 Nm if your vehicle has the 210 axle. Remove the rear exhaust system and the wheel/tire assembly from the end that is spin off for V8 models (2 and 1). First, take out and throw away the wheel hub nut (1) and afterwards apply index marks (3) to both the propeller shaft rubber coupler (1) and the axle flange (2). Unbolt the three propeller shaft coupler-to-axle flange bolt/nuts and unscrew the front and rear shaft clamp screw to disengage each halfshaft (2) from the axle. If you aren't using a transmission jack, use a pry to compress the rear suspension, then remove the bolt/nut (2) and two bolts (1) securing the rear axle forward isolator to the isolator mount. As you remove the rear axle, hold up the propeller shaft with some helpful rope or wire (1). Take off the halfshafts one by one, keeping the axle assembly so that you can compress one halfshaft while removing the other (1). If the rubber isolation washer (1) looks worn, make sure to remove it and use a good screwdriver to remove the axle seals (2). To perform installation, work around the differential cover and implement Tool 9223 (2) to mount the new axle seal(s) (1) and a bidirectional halfshaft isolation washer (1). Screw the halfshaft (2) into the wheel hub/knuckle assembly and tighten a new hub nut (1) manually. Pour Mopar Gear and Axle Lubricant (75W-140) inside the halfshaft inner joint bearing journal and then install the halfshaft on the rear axle, holding it securely with new circlip(s) to not touch the rear axle seals. Raise the rear axle up, match the propeller shaft index marks (3) and begin to thread the bolt/nuts that hold the propeller shaft coupler to the axle by hand. Bolt the two axle-to-crossmember bolts (1) with a torque of 220 Nm (162 ft. lbs.), then tighten the bolt/nut on the rear axle front mount isolator (1) to 65 Nm (48 ft. lbs.). Press the inner joints of the halfshafts into the axle assembly, remove the transmission jack (1) and if needed, take out the screw-type under-hoist jack stands (2). Apply a force of 58 Nm (43 ft. lbs.) to the propeller shaft coupler-to-axle flange bolt and nut, then take out the rear axle fill plug (1) with a 14mm hex. Fill the axle with Mopar 75W-140 Synthetic Gear & Axle Lubricant, using 1.4L (1.5 qts.) for the 198 and 1.6L (1.7 qts.) for the 210 axle. Place and tighten the fill plug (1) to 60 Nm for the 198 axle and to 50 Nm for the 210 axle. On V8 models, place the exhaust system and tighten the band clamps (1) to 61 Nm (45 ft. lbs.). Now, drive the halfshaft into the gear, tighten its hub nut (1) to 213 Nm (157 ft. lbs.), mount the center cap and then tighten the lug nuts of the wheel/tire assembly (1) to 150 Nm (110 ft. lbs.).
