On the right side, remove the clamps, slide the rubber boot onto the stub shaft and pull out the shaft and joint assembly. For spindle bearing and oil seal replacement, remove the bearing and oil seal with a slide hammer and puller attachment. Clean the spindle bore and install a new bearing and seal. To replace axleshaft assembly universal joint, remove snap-rings, and proceed as for driveshaft universal joints. Press slinger onto spindle, install rubber boot with clamps on stub shaft slip yoke to reassemble. Slide through knuckle shaft and joint assembly engaging splines. Install splash shield, spindle, wheel bearings, locking hubs, brake caliper, and front wheels.

Installation is otherwise the reverse of removal.

Raise the front of the vehicle, support it securely on jackstands, and remove the front wheels.

Tilt the driver's side of the axle housing down, lower the axle, move it toward the driver's side, and remove it from beneath the vehicle.

The axle identification number is important for undertaking certain operations, particularly the replacement of the axleshafts. It is located on a small metal tag near one of the cover bolts.

The overhaul and general repair of the rear axle are beyond the scope of the home mechanic due to the many special tools and critical measurements required. Therefore, the procedures listed will involve axleshaft removal and installation, axleshaft oil seal replacement, axleshaft bearing replacement, and removal of the entire unit for repair or replacement.

Tilt the driver's side of the axle housing down, lower the axle, move it toward the driver's side, and remove it from beneath the vehicle.
