REMOVAL & INSTALLATION
Except Conquest and 4WD Vista
A press is necessary for bearing removal and installation. After the axle has been removed, an automotive machine shop can press off and install the axle bearing.
- Remove the wheel, tire and brake drum.
- Remove the nuts holding the axle retainer plate to the backing plate.
- Remove the retainer. Install the nuts finger-tight, to prevent the backing plate from being dislodged.
- Pull the axleshaft and bearing from the axle housing. A slide hammer puller will make the job easier. Remove the oil seal from the axle housing.
- Using a chisel, nick the bearing retainer ring in three or four places. The retainer does not have to be cut, merely collapsed sufficiently to allow the retainer ring to slide from the shaft and not resist when the bearing is pressed off.
- Press off the old bearing, and install the new one.
- Press on the new retaining ring.
Do not attempt to press the bearing and retainer on at the same time.
- Install a new oil seal in the axle housing, after cleaning the mounting surface of the housing.
- Install the axle. Secure the retaining plate. Install the brake drum and wheel.
The term axleshaft refers to the shaft enclosed in the flange and housing at the rear wheel. The shaft between the differential and axleshaft is termed the intermediate shaft. A press is required for bearing replacement.
- Raise and safely support the vehicle on jackstands.
- Disconnect the parking brake cable from the rear calipers.
- Remove the caliper, caliper support and rotor. Don't disconnect the brake line from the caliper, just suspend the caliper out of the way with wire.
- Remove the intermediate shaft and companion shaft.
- Remove the axleshaft housing from the lower control arm.
- Remove the strut assembly from the axleshaft housing.
- Loosen the companion flange nut and tap the axleshaft out of the housing with a plastic mallet. Take care not to damage the oil seal.
- Remove the spacer and dust covers from inside the housing.
Don't remove the bearings unless you intend to replace them, since they will be damaged during removal.
- Remove the outer bearing with a puller.
- Using a brass drift, drive the inner bearing and seal from the housing.
- Press the new outer bearing onto the shaft with the seal side facing the companion flange side of the shaft.
- Pack the housing with lithium based wheel bearing grease.
- Press the inner bearing onto the shaft with the seal side facing the companion side of the shaft.
- Grease the seal bore in the housing and drive the new seal into position.
- Install the dust covers.
- Insert the axleshaft and spacer into the housing and attach the companion flange.
- Place the housing in a vise, then install and tighten the companion flange nut to 200-220 ft. lbs.
- Install all the other parts. Check the axleshaft end-play with a dial indicator. End-play should be 0.8mm on vehicles with four lug wheel, and 0.13-0.20mm on vehicles with five lug wheels. If the end-play exceeds the limits, the bearing needs replacing or it has been assembled incorrectly.
- Raise and safely support the rear of the vehicle, with the suspension hanging free.
- Remove the rear wheels.
- Remove the brake drums.
- Remove the bolts securing the axle flange to the intermediate shaft flange.
- Remove the axle flange nut.
- Use a slide hammer puller, and remove the axleshaft from the housing.
- Remove the lower control arm.
- Remove the dust cover and outer wheel bearing and seal from the axleshaft with an appropriate puller.
- Press the inner bearing and seal from the housing. Pack the new bearing with grease and press into place.
- Install the new inner bearing seal.
- Install the dust cover into place evenly in the housing.
- Coat the lip of a new seal and pack the outer bearing with grease.
- Press in the bearing and seal.
- Press the axleshaft into the inner arm.
- Install the inner arm assembly.
- Install the companion flange and nut. Torque the nut to 160 ft. lbs.
- Connect the intermediate shaft and axleshaft. Torque the bolts to 43 ft. lbs.
