Rear Suspension

Knuckle/Hub Replacement

Knuckle/Hub:

Special Tools Required
^ Ball joint remover, 32 mm 07MAC-SLOA102

Hub Replacement
1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the rear wheel.





3. Remove the brake caliper bracket mounting bolts (A), and remove the caliper assembly (B) 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.





4. Remove the two washers W.





5. Remove the wheel sensor (A) and O-ring (B) from the knuckle. Do not disconnect the wheel sensor connector.

NOTE: Use a new O-ring on reassembly.





6. Raise the stake (A), and remove the spindle nut (B).





7. Remove the 6 mm brake disc retaining screws (A).





8. Screw two 8 x 1.25 mm bolts (B) into the disc to push it away from the hub. Turn each bolt two turns at a time to prevent cocking the disc excessively.
9. Remove the brake disc/drum (C).
10. Remove the hub bearing unit (A).





11. 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 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/drum, clean the mating surfaces of the hub bearing Unit and the inside of the brake disc/drum.
^ Before installing the wheel, clean the mating surfaces of the brake disc/drum and the inside of the wheel.

Knuckle Replacement
1. Remove the hub bearing unit.
2. Remove the lower arm A mounting nut (B), washers (C), and mounting bolt (D) from the knuckle side.





3. Remove the self-locking nut (E), washers (F), and the flange bolt (G), then remove the lower arm A.
4. Remove the backing plate mounting nuts (A), then remove the backing plate (B). To prevent damage to the backing plate or parking brake shoes assembly and cable, use a short piece of wire to hang the backing plate from the undercarriage. Do not twist the parking brake cable with force.





5. Remove the wheel sensor bracket (A) from the knuckle. Do not disconnect the wheel sensor connector.

NOTE: Use a new bracket on reassembly.





6. Remove the lock pin (A) from the upper arm ball joint, then loosen the nut (B).

NOTE: During installation, install the new lock pin as shown after tightening the nut.





7. Disconnect the upper arm ball joint from the knuckle using the ball joint remover.
8. Remove the self-locking nut (A) and the washer (C), then disconnect the stabilize link (D) from lower arm B.





9. Remove the damper lower mounting bolt (A), and disconnect the damper (B) from the knuckle.





10. Place a floor jack at the connecting point of lower arm B and the stabilizer link.
11. Remove the cotter pin (A) from the lower arm B ball joint, and loosen the nut (C).

NOTE: During installation, insert the now cotter pin into the ball joint pin hole from the rear to the front of vehicle, and bend its end as shown.





12. Disconnect the knuckle ball joint from the lower arm B using the ball joint remover.
13. Remove the control arm mounting nut (A) and washer (B) from the knuckle (C), then remove the knuckle.





14. Install the knuckle in the reverse order of removal, and note these items:
^ Before connecting the ball joint to the knuckle and the lower arm B, 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.
^ Be careful not to damage the ball joint boot when connecting the knuckle to the lower arm B and upper arm to the knuckle.
^ 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.
^ Tighten all mounting hardware to the specified torque values.
^ Use a new lower arm A mounting nut, the self locking nuts, and control arm mounting nut on reassembly.
^ 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 disc/drum and the inside of the wheel.
^ Check the wheel alignment, and adjust if necessary.
