in Suspension General Diagnosis.
Installation Procedure
Important:
• | Make sure all of the 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, the shoulder, and the
seal seat. |
• | Also, finger apply a small amount of grease inboard of each bearing
cup in the hub/rotor. |
• | Pressure pack the bearings with a greasing machine, or hand pack
the bearings. Make sure the grease is worked thoroughly into the rollers,
the cone, and the cage. |
- Install the inner bearing
to the hub/rotor.
- Apply an additional quantity of grease outboard of the inner bearing.
- Install the seal.
3.1. | Lubricate the seal lip. |
3.2. | Use a seal installation tool or a flat block 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.
- Install the hub/rotor to the spindle.
- Install the outer bearing to the hub/rotor.
- Install the washer.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important: Adjust the wheel bearings. Refer to
Wheel Bearing Adjustment
.
- Install the nut.
Tighten
- Tighten the nut to 16 N·m (12 lb ft),
while turning the wheel assembly forward by hand.
- Apply grease to the outboard side of the outer bearing.
- Install the brake caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
