- Raise and support the vehicle safely. Remove the tire and wheel assembly from the hub and rotor.
- Remove the caliper from its mounting and position it to the side with mechanics wire in order to prevent damage to the brake line hose.
- Remove the grease cap from the hub. Remove the cotter pin, retainer, adjusting nut and flatwasher from the spindle.
- Remove the outer bearing cone and roller assembly from the hub. Remove the hub and rotor from the spindle.
- Using seal removal tool 1175-AC or equivalent remove and discard the grease seal. Remove the inner bearing cone and roller assembly from the hub.
- Clean the inner and outer bearing assemblies in solvent. Inspect the bearings and the cones for wear and damage. Replace defective parts, as required.
- If the cups are worn or damaged, remove them with front hub remover tool T81P-1104-C and tool T77F-1102-A or equivalent.
- Wipe the old grease from the spindle. Check the spindle for excessive wear or damage. Replace defective parts, as required.
- If the inner and outer cups were removed, use bearing driver handle tool T80-4000-W or equivalent and replace the cups. Be sure to seat the cups properly in the hub.
- Use a bearing packer tool and properly repack the wheel bearings with the proper grade and type grease. If a bearing packer is not available work as much of the grease as possible between the rollers and cages. Also, grease the cone surfaces.
- Position the inner bearing cone and roller assembly in the inner cup. A light film of grease should be included between the lips of the new grease retainer (seal).
- Install the retainer using the proper installer tool. Be sure that the retainer is properly seated.
- Install the hub and rotor assembly onto the spindle. Keep the hub centered on the spindle to prevent damage to the spindle and the retainer.
- Install the outer bearing cone and roller assembly and flatwasher on the spindle. Install the adjusting nut. Adjust the wheel bearings.
- Install the retainer, a new cotter pin and the grease cap. Install the caliper.
- Lower the vehicle and tighten the lug nuts to 100 ft. lbs. Before driving the vehicle pump the brake pedal several times to restore normal brake pedal travel.
See Figure 1
- Raise and support the vehicle safely. Remove the wheel cover. Remove the grease cap from the hub.
- Wipe the excess grease from the end of the spindle. Remove the cotter pin and retainer. Discard the cotter pin.
- Loosen the adjusting nut 3 turns.
- While rotating the wheel assembly, tighten the adjusting nut to 17-25 ft. lbs. in order to seat the bearings. Loosen the adjusting nut a half turn. Retighten the adjusting nut 18-20 inch lbs.
- Place the retainer on the adjusting nut. The castellations on the retainer must be in alignment with the cotter pin holes in the spindle. Once this is accomplished install a new cotter pin and bend the ends to insure its being locked in place.
- Check for proper wheel rotation. If correct, install the grease cap and wheel cover. If rotation is noisy or rough recheck your work and correct as required.
- Lower the vehicle and tighten the lug nuts to 100 ft. lbs., if the wheel was removed. Before driving the vehicle pump the brake pedal several times to restore normal brake pedal travel.
