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 caliper mounting bolts (B), and hang the caliper assembly (C) to one side. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper from the undercarriage.
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 (A) from the hub bearing unit.
NOTE:
^ Remove the access plug (B), then, if necessary, turn the adjuster bolt (C) with a flat-tip screwdriver until the shoes become loose if necessary.
^ If the brake disc/drum has clung to the hub bearing unit. Screw two 8 x 1.25 mm bolts (D) into the brake disc/drum to push it away from the hub bearing unit. Turn each bolt 90 degrees at a time to prevent cocking the brake disc/drum.
^ After installation, press the brake pedal several times to make sure the brakes work if adjusted to loosen the shoes.
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:
^ Tighten all mounting hardware to the specified torque values.
^ 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.
Knuckle Replacement
1. Remove the hub bearing unit.
2. Remove the parking brake cable (A) from the trailing arm (B).
3. Remove the flange nuts (C), then remove the backing plate (D).
NOTE: To prevent damage to the backing plate or parking brake cable, use a short piece of wire to hang the backing plate from the undercarriage. Do not twist the parking brake cable excessively.
4. Remove the wheel sensor (A) from the knuckle (B). Do not disconnect the wheel sensor connector.
NOTE: During installation, apply multipurpose grease to inside of the hole (C) on the knuckle.
5. Remove the lock pin (A) from the upper arm ball joint (B), and loosen the castle nut (C).
NOTE: During installation, install the lock pin after tightening the new castle nut.
6. Disconnect the upper arm ball joint from the knuckle using the ball joint remover, 32 mm.
7. Remove the self-locking nut (B), the washer (C), and the flange bolt (D), then remove lower arm A.
NOTE: During installation, install a new self-locking nut, a new washer, and a new flange bolt.
8. Remove the self-locking nuts (A), and separate the knuckle from the trailing arm (B).
NOTE: During installation, install the new self-locking nuts.
9. Position a floor jack under the lower arm B.
10. Remove the flange bolt (A), then remove the knuckle (C).
NOTE: During installation, install a new flange bolt.
11. Install the knuckle in the reverse order of removal, and note these items:
^ Be careful not to damage the ball joint boot when installing the knuckle.
^ Tighten all mounting hardware to the specified torque values.
^ 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.
^ 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.
^ 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.
^ Check the wheel alignment, and adjust it if necessary.
