the rotor.
- Remove the cotter pin, the nut, and the washer.
- Remove the wheel hub and bearing assembly from the spindle.
- Remove the outer bearing.
- Remove the seal. Pry the seal out and discard the seal.
- Remove the inner bearing.
- Clean all of the parts in a solvent, then air dry. Do not spin
the bearings with compressed air.
- Make sure all of the parts are clean and free of grease.
- Inspect the rotor. Refer to
Brake Rotor Thickness Variation Check
or
Brake Rotor Lateral Runout Check
or
Brake Rotor Tolerance
in Disc Brakes.
- Inspect the bearings and the races for wear or damage. Refer to
Wheel Bearings Diagnosis
in Suspension General Diagnosis.
- Remove the inner and outer
races using J 29117-A
,
if necessary.
Installation Procedure
Important:
• | Make sure that 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 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. |
- Install the inner and
outer races, if necessary.
- Install the inner bearing to the rotor.
- Apply an additional quantity of grease outboard of the inner bearing.
- Install the seal.
4.1. | Lubricate the seal lip. |
4.2. | Use a flat plate in order to press the seal down flush with the
hub. |
4.3. | Seat the outer bearing and the cup. |
Important: Do not scuff the spindle threads.
- Install the Wheel hub and bearing assembly to the spindle.
- Install the outer bearing to the 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.
- Install the spindle
nut.
Tighten
- Tighten the spindle nut to 16 N·m (12 lb ft),
while turning the wheel assembly forward by hand.
- Adjust the wheel bearings. Refer to
Wheel Bearing Adjustment
.
- Install new cotter pin. Bend the pin ends against the nut flats.
- Install the dust cap to rotor.
- Install the brake caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
- Lower the vehicle.
