REMOVAL, PACKING AND INSTALLATION
See Figures 1 through 14
- Raise and support the vehicle safely on jackstands. See the procedure on jacking in this section.
- Remove the wheel and tire assembly. If equipped with disc brakes, remove the disc brake caliper. Suspend the caliper with a length of wire; do not let it hang from the brake hose.
- Pry off the dust cap. Remove and discard the cotter pin.
- Remove the nut retainer.
- Loosen, then remove the retaining nut.
- Remove the outer wheel bearing from the hub.
- Remove 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 (cups). If either bearings or races are damaged, the bearing races must be removed and the bearings and races replaced as an assembly.
- If the bearings are to be replaced, drive out the races (cups) from the hub using a brass drift, or pull them from the hub using a puller.
- Make sure the spindle, hub and bearing assemblies are clean prior to installation.
- If the bearing races (cups) were removed, install new ones using a suitable bearing race installer. Pack the bearings with high-temperature wheel bearing grease using a bearing packer. If a packer is not available, work as much grease as possible between the rollers and cages using your hands.
- Coat the inner surface of the hub and bearing races (cups) with grease.
- Install the inner bearing in the hub. Using a seal installer or an appropriate sized socket, install a new grease seal into 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 caliper and the wheel and tire assembly. Adjust the bearings as follows:
- Loosen the adjusting nut 3 turns and rock the wheel in and out a few times to release the brake pads from the rotor.
- While rotating the wheel and hub assembly in a counterclockwise direction, tighten the adjusting nut to 17-25 ft. lbs. (23-34 Nm).
- Back off the adjusting nut 1 / 2 turn, then retighten to 10-28 inch lbs. (1.1-3.2 Nm).
- Install the nut retainer and a new cotter pin. Replace the grease cap.
- Lower the vehicle. Before driving the vehicle, pump the brake pedal several times to restore normal brake pedal travel.
