Front

NOTES:
- The front hub/bearing used on this vehicle is serviceable only as a complete assembly. No attempt should ever be made to disassemble a front hub/bearing in an effort to repair it.

- Replacement of the front hub/bearing can be done without having to remove the steering knuckle from the vehicle.

REMOVE
1. Raise vehicle on jackstands or centered on a frame contact type hoist.





2. Remove the center cap from the wheel. Center cap is removed by inserting a trim stick into the notch on the center cap and prying it off the wheel.
3. Remove wheel and tire





4. Remove the 2 bolts attaching the brake caliper to the caliper adapter.





5. Remove the disc brake caliper from the caliper adapter. Caliper is removed by first rotating the tree end of the caliper away from the caliper adapter. Then with the free end of the caliper rotated away from the adapter, lift the caliper off the machined abutment on the adapter.





NOTE: The upper control arm on this vehicle has a clear-coat finish applied to it. When hanging the disc brake caliper from the control arm do not use wire or any similar material that would damage the clear-coat finish. A plastic tie strap as shown is a suitable method of supporting the disc brake caliper.

6. Support the disc brake caliper firmly by hanging it from the upper control arm using a tie strap. Do not let the flex hose support the weight of the brake caliper, damage to the flex hose can occur.
