INSTALLATION PROCEDURE





Important:
^ Apply an approved high temperature front wheel bearing grease to the spindle at the inner and outer bearing seat, the shoulder, and the seal seat. Also, finger apply a small amount of grease inboard of each bearing cup in the rotor.
^ Pressure pack the bearings with a grease machine, or hand pack the bearings. Make sure the grease is worked thoroughly into the rollers, the cone, and the cage.

1. Install the inner bearing to the rotor.
2. Apply an additional quantity of grease outboard of the inner bearing.
3. Install the seal.
3.1. Lubricate the seal lip.
3.2. Use a flat plate in order to press the seal down flush with the hub.
3.3. Seat the outer bearing and the cup.

Important: Do not scuff the spindle threads.

4. Install the rotor to the spindle.
5. Install the outer bearing to the rotor.
6. Install the washer.

Important: Adjust the wheel bearings.

NOTICE: 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.

7. Install the nut.
7.1. Tighten the nut to 16 Nm (12 lb ft), while turning the wheel assembly forward by hand.
7.2. Apply grease to the outboard side of the outer bearing.

8. Install the brake caliper.
