See Figures 1, 2 and 3
Do not use old bearings with new races or vise versa. Only use bearings in a matched set.
- Disconnect the negative battery cable.
- Raise and safely support the vehicle, then remove the rear wheels.
- On drum brakes, insert a small pry tool through a wheel bolt hole and push up on the adjusting wedge to slacken the rear brake adjustment.
- On disc brakes, remove the caliper.
- Remove the grease cap, cotter pin, locking ring, axle nut and thrust washer. Carefully remove the bearing and put all these parts where they will stay clean.
- Remove the brake drum or rotor and pry out the inner seal to remove the inner bearing.
- Clean all the grease off the bearings using solvent. If the bearings appear worn or damaged, they must be replaced.
- To remove the bearing races, support the drum or rotor and carefully drive the race out with a long drift pin. They can also be removed on a press.
- Carefully press the new race into the drum or rotor. The old race can be used as a press tool but make sure it does not become stuck in the hub.
- Pack the inner bearing with clean wheel bearing grease and fit it into the inner race. Press a new axle seal into place by hand.
- Lightly coat the stub axle with grease and install the drum or rotor. Be careful not to damage the axle seal.
- Pack the outer bearing, then install the bearing, thrust washer and nut.
To adjust the bearing pre-load:
- Begin tightening the nut while turning the drum or rotor.
- When the nut is snug, try to move the thrust washer with a screwdriver.
- Back the nut off until the thrust washer can be moved without prying or twisting the screwdriver.
- Without turning the nut, install the locking ring so a new cotter pin can be installed through the hole in the stub axle. Bend the cotter pin.
- Pack some grease into the cap and install it.
- Connect the battery cable.
