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.

• | Pull the hub/rotor free from the spindle. Make sure the outer
wheel bearing comes free. |
• | Do not damage the steering knuckle spindle threads. |
- Remove the inner wheel bearing. Pry out the seal.
- Remove the races. Using a brass drift, drive out each race.

Notice: Do not spin the wheel bearings with compressed air to dry them-the
wheel bearings may be damaged.
- Using clean solvent and a small brush with no loose bristles, clean
any grease from the wheel bearings and the races.
- Inspect the wheel bearings and the races for damage or wear.
• | If a bearing or the race is damaged, replace both of these. |
- Inspect the hub/rotor for damage or wear.
• | Check for out of round or scored conditions. |
• | Check for pitting or cracks. |
• | If necessary, repair or replace the hub/rotor. |
Installation Procedure
For Front Spring and Components refer to
Front Spring and Components (C3500HD)
Notice: Start the races squarely inside the hub/rotor to avoid distortion and
possible cracking.
- Install the races into the hub/rotor.
1.1. | Place the hub/rotor on the J 9746-02
. Rest this assembly on the press bars. |
1.2. | Using a 7.6 cm (3 in) diameter bar, or equivalent,
press the outer bearing race into position. |
1.3. | Remove the J 9746-02
and use a 7.6 cm (3 in) diameter bar, or equivalent,
in order to press the inner bearing race into position. If the bar is larger
than 7.6 cm (3 in), the bar may damage the bearing seal
seat. |
Important:
• | Use an approved, high-temperature front wheel bearing grease in
order to lubricate the bearings. Refer to
Fluid and Lubricant Recommendations
in Maintenance and Lubrication. |
• | Do not mix different greases because mixing may change the grease
properties, resulting in poor performance. |
- Apply a thin film of grease to the steering knuckle spindle at the outer
wheel bearing seat and at the inner wheel bearing seat, the shoulder, and
the seal seat.
- Apply a small amount of grease inboard of each wheel bearing retainer/cap.
Notice: Failure to completely pack the wheel bearing (cones, rollers, and cage)
with grease will result in premature wheel bearing damage and/or wear.
- Fill each wheel bearing (cone and roller assembly) full of grease.
• | Use a cone-type grease machine that forces grease into the bearing. |
• | If a cone-type grease machine is not available, pack the wheel
bearing by hand. When packing the wheel bearing by hand, work the grease into
the bearings between the rollers, the cones, and the cage. |
- Install the inner wheel bearing into the hub/rotor. Put an additional
quantity of grease outboard of this bearing.
- Install the new seal.
6.1. | Using a seal installer or a block, install the seal in order to
ensure that the seal is flush with the hub/rotor flange. |
6.2. | Lubricate the seal lip with a thin layer of grease. |
- Install the hub/rotor. Do not damage the steering knuckle spindle
threads.
- Install the outer wheel bearing. Slide the bearing over the spindle
until the wheel bearing fully seats against the hub/rotor outer race.
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.
