- Raise and safely support the front of the vehicle.
- Remove the wheel cover and grease cap.
- Remove the cotter pin and nut retainer.
- Loosen the adjusting nut 3 turns, then rock the wheel back and forth a few times to release the brake pads from the rotor.
- While rotating the wheel and hub assembly, tighten the adjusting nut to 17-25 ft. lbs. (23-34 Nm), to seat the bearings.
- Back off the adjusting nut 1 / 2 turn, then retighten to 10-15 inch lbs. (1.1-1.7 Nm).
- Install the nut retainer and a new cotter pin. Check the wheel rotation. If it is noisy or rough, the bearings either need to be cleaned and repacked or replaced. After adjustment is completed, install the grease cap and wheel cover.
- Lower the vehicle. Before driving the vehicle, pump the brake pedal several times to restore normal brake pedal travel.
REMOVAL & INSTALLATION
See Figures 1 through 13
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly, then remove the brake caliper. Suspend the caliper with a length of wire; do not let it hang from the brake hose.
- Pry off the dust cap. Unbend, tap out and discard the cotter pin. Remove the nut retainer.
- Remove the castellated nut and washer from the spindle.
- Being careful not to drop the outer bearing, pull off the brake disc and wheel hub assembly.
- Remove the inner grease seal using a small prytool. Remove the inner wheel bearing.
- Clean the wheel bearings with solvent and inspect them for pits, scratches and excessive wear. Wipe all the old grease from the hub and inspect the bearing races. If either bearings or races are damaged, the races must be removed, then the bearings and races must be replaced as an assembly.
- If the bearings are to be replaced, drive out the races from the hub using a brass drift.
- Make sure the spindle, hub and bearing assemblies are clean prior to installation.
- If the bearing races were removed, install new ones using a suitable bearing race installer. Grease the bearings with a bearing packer. If a packer is not available, work as much grease as possible between the rollers and cages.
- Coat the inner surface of the hub and bearing races with grease.
- Install the inner bearing in the hub. Being careful not to distort it, install the oil seal with its lip facing the bearing. Drive the seal in until its outer edge is even with the edge of the hub. Lubricate the lip of the seal with grease.
- Install the hub/disc assembly on the spindle, being careful not to damage the oil seal.
- Install the outer bearing, washer and spindle nut. Install the brake caliper along with the wheel and tire assembly.
- Adjust the wheel bearings, as described earlier in this section. Be sure to install the nut retainer with a new cotter pin. After adjustment is completed, install the dust cap and wheel cover.
- Lower the vehicle. Before driving, pump the brake pedal several times to restore normal brake pedal travel.
