Hub, Bearing and Seal

FRONT HUB/BEARING






REMOVAL
Remove or disconnect the following:
1. Brake caliper.

NOTE: Support the caliper with a piece of wire to prevent damage to the brake line.

2. Cap (10) from the hub/rotor (17).
3. Cotter pin (11), nut (12) and washer (13).
4. Hub/rotor (17) from the spindle.
- Be careful not to damage the outer bearing (14) and the spindle threads.
5. Outer bearing (14).
6. Seal (20). Pry the seal (20) out and discard.
7. Inner bearing (19).
8. Clean All parts in a solvent and air dry. Do not spin the bearings with compressed air.
9. Inspect the following:
- Hub/rotor (17).
- Bearings (14 and 19) and races for a cracked cage, worn or pitted rollers, cracks, scores, or a brinelled condition.

INSTALLATION

CAUTION: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion Inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.


NOTE:
- Be sure all parts are clean and free of grease.
- Apply an approved high-temperature front wheel bearing grease to the spindle at the inner and outer bearing seat, shoulder and seal seat. Also finger apply a small amount of grease inboard of each bearing cup in the hub/rotor (17).
- Pressure pack the bearings (14 and 19) with a greasing machine or hand pack them, making sure the grease is worked thoroughly into the rollers, cone and the cage.

Install or connect the following:
1. Inner bearing (19) to the hub/rotor (17). Apply an additional quantity of grease outboard of the inner bearing (19).
2. Seal (20).
- Lubricate the seal (20) lip.
- Use a seal installation tool or flat block to press the seal (20) down flush with the hub.
- Seat the outer bearing (14) and cup (15).
3. Hub/rotor (17) to the spindle.
- Be careful not to scuff the spindle threads.
4. Outer bearing (14) to the hub/rotor (17).
5. Washer (13).
6. Nut (12). Tighten (12) to 16 Nm (12 lb ft) while turning the wheel assembly forward by hand. Apply grease to the outboard side of the outer bearing (14).

NOTE: Adjust the wheel bearings.

7. Brake caliper.
