Hub Bearing Unit Replacement
1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the wheel nuts (A) and rear wheel.
3. Remove flange nuts (A), then remove the brake hose mounting bracket.
4. Remove the brake caliper mounting bolts (B), then 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 excessively.
5. Remove the two washers (A).
6. Raise the stake (A), then remove the spindle nut (B).
7. Release the parking brake, and remove the brake disc/drum.
8. Remove the hub bearing unit (A).
9. Check the rear hub bearing unit for damage and cracks.
10. Install the hub bearing unit in the reverse order of removal, and note these items:
^ Use a new spindle nut during 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/drum, clean the mating surface of the hub bearing unit and the inside of the brake disc/drum.
^ Before installing the wheel, clean the mating surface of the brake disc/drum and the inside of the wheel.
^ Check the wheel alignment, and adjust it if necessary.

NOTE: During installation, install a new flange bolt.
11. 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 installing the knuckle.
^ Before connecting the lower ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the knuckle connecting hole, 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.
^ Use a new spindle nut during 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 surface of the front hub and the inside of the brake disc.
^ Before installing the wheel, clean the mating surface of the brake disc and the inside of the wheel.
