FRONT HUB/BEARING

REMOVAL PROCEDURE
^ Tools Required:
- J 28733 Front Hub Spindle Remover

1. Raise the vehicle. Support the vehicle by the frame. Allow the control arms to hang free.
2. Remove the wheel and tire assembly.
3. Clean the drive axle threads of all dirt. Lubricate the threads.





4. Remove the drive axle nut. Insert a drift punch or a screwdriver into the caliper and the rotor in order to prevent the rotor from turning.
5. Remove the caliper bolts. Support the caliper.
6. Remove the rotor.





7. Disconnect the ABS front wheel speed sensor connector. Unclip the connector from the dust shield.





8. Remove the hub and bearing retaining bolts.
9. Remove the dust shield.
10. Place the transmission in PARK.

Important: Replace the hub and bearing only as an assembly.

11. Use the J 28733 in order to separate the hub and bearing from the drive axle.
12. Clean the rust and the foreign material from the following components in order to allow proper seating of the bearing into the knuckle:
^ The knuckle mounting face
^ The bore
^ The chamber

INSTALLATION PROCEDURE





1. Install the hub and bearing to the drive axle. Apply a thin layer of grease to the knuckle bore. Remove the protective plastic cover before installation. Do not handle the knuckle or hub assembly by the ABS sensor wire.
2. Install the new drive axle nut, draw hub and bearing onto the axle.
3. Place the transmission in NEUTRAL.

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.

4. Carefully install the dust shield. Do not damage the bearing outboard lip seal, or the hub and bearing bolts.
