For wheel bearing removal and installation procedure on all 4WD models, refer to the Rear Axle section.
REMOVAL & INSTALLATION
- Apply the hand brake and loosen the rear wheel lug nuts.
- Raise and support the rear of the vehicle with jackstands. Remove the rear wheel assemblies.
- If equipped with rear disc brakes, remove the caliper and support it on a wire.
- Using a small prybar, remove the rear wheel grease cap.
- Using a hammer and a punch, flatten the lock washer and loosen the axle nut. Remove the lock washer and the thrust plate.
- When removing the drum or disc, be careful not to drop the inner race from the outer bearing.
- Using a gear puller, remove the spacer and the inner race of the inner bearing.
- Using a brass drift and a hammer, drive the outer race of the inner bearing (with the oil seal) from the drum or disc.
- Using a brass drift and a hammer, drive the outer race of the outer bearing from the drum or disc.
- Clean and inspect the parts for damage, wear and/or corrosion; replace the parts, if necessary.
- Using the Bearing Installation tool No. 925220000 or equivalent, press the outer race of the inner bearing into the drum or disc until it seats against the shoulder.
When pressing the bearing, be sure not to exceed the load to the bearing, so as not to damage it.
- Apply a small amount of grease to the oil seal lips, then install the oil seal until it is flush with the drum or disc.
- Using the Bearing Installation tool No. 921130000 or equivalent, press the outer race of the outer bearing into the drum or disc until it seats against the shoulder.
- Apply approximately 1 / 8 oz. (3.5 g) of wheel bearing grease to the inner and the outer bearings. Fill the disc or drum hub with 1 oz. (28 g) of wheel bearing grease.
- Install a new spacer O-ring, the spacer and the inner race of the inner bearing onto the trailing arm spindle.
When installing the spacer, be sure to face the stepped surface toward the bearing. Use a new thrust plate and lock washer.
- To complete the installation, reverse the remaining removal procedures. Adjust the wheel bearing.
- Temporarily tighten the axle nut to 36 ft. lbs. 48 Nm), turn the drum or disc (back and forth) several times to ensure that the bearings are properly seated.
- Rotate the nut backwards 1 / 8 turn in order to obtain the correct starting force.
- Using a spring gauge, at a 90° angle to the wheel lug, check the rotating force; the force should be 1.9-3.2 ft. lbs. (2-4 Nm).
- After adjustment is complete, bend the lock washer.
- After installing a new O-ring to the grease cap, install the cap with a plastic hammer.
