Hub Bearing Unit Replacement
1. Raise the front of the vehicle, and support it with safety stands in the proper locations.
2. Remove the front wheel, taking care not to scratch the caliper.
3. Remove the brake hose mounting bracket (A).
4. Remove the brake caliper bracket mounting bolts (B), and remove the caliper assembly (C) from the knuckle. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose with force.
5. Remove the wheel sensor (A) and O-ring (B) from the knuckle. Do not disconnect the wheel sensor connector.
6. Raise the stake (A), then remove the spindle nut (B).
7. Remove the brake disc.
8. Remove the hub bearing unit mounting bolts (A).
9. Remove the hub bearing unit (B) by tapping the driveshaft end (C) with a plastic hammer while drawing the hub bearing unit outward.
10. Install the hub bearing unit in the reverse order of removal, and note these items:
^ Use a new spindle nut on reassembly.
^ Before installing the spindle nut, apply a small amount of engine oil to the seating surface of the nut. After tightening, use a drift to stake the spindle nut shoulder against the driveshaft.
^ Before installing the brake disc, clean the mating surfaces of the front hub bearing unit and the inside of the brake disc.
^ Before installing the wheel, clean the mating surfaces of the brake disc and the inside of the wheel.
Knuckle Replacement
1. Remove the hub bearing unit.
2. Remove the splash guard (A).
3. Remove the wheel sensor (A) from the knuckle. Do not disconnect the wheel sensor connector.
NOTE: Use a new wheel sensor bracket (B) and new clips (C) on reassembly.
4. Remove the cotter pin (A) from the tie-rod end ball joint, then loosen the nut (B).
NOTE: During installation, install the new cotter pin after tightening the nut, and bend its end as shown.
5. Disconnect the tie-rod end ball joint from the knuckle using the ball joint remover.
6. Remove the holder (A) from the knuckle (B).
NOTE: Use a new flange bolt and self-locking nut during reassembly.
7. Remove the lock pin (A) from the upper arm ball joint, and loosen the nut (B).
NOTE: During installation, install the new lock pin as shown after tightening the nut.
8. Disconnect the upper arm ball joint from the knuckle using the ball joint remover, then remove the knuckle.
9. Install the knuckle in the reverse order of removal, and note these items:
^ First install all the components and lightly tighten the bolts and nuts, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
^ Be careful not to damage the ball joint boot when connecting the upper arm to the knuckle.
^ Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the connecting hole, and the threaded section and mating surface of the castle nut.
^ Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
^ Before installing the wheel, clean the mating surfaces on the brake disk and the inside of the wheel.
^ Check the wheel alignment, and adjust it if necessary.
