NOTE: The illustrations show only the rear disc brake type of the vehicle except where the procedure is different for the rear drum in disc brake type.
  1. Remove the rear wheel.
  1. Release the parking brake lever fully.
  1. Rear disc brake type: Remove the flange bolt (A) from the arm (B). Then disconnect the parking brake cable from the lever (C).

  1. Remove the brake caliper bracket mounting bolts (A), then remove the caliper assembly (B) from the knuckle. To prevent damage to the caliper assembly or the brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose excessively.

  1. Remove the lock pin (A) from the upper arm ball joint, then remove the castle nut (B).
    NOTE: During installation, install the lock pin as shown after tightening the new castle nut.

  1. NOTE:
    • Be careful not to damage the ball joint boot when installing the remover.
    • During installation, to connect the ball joint, position a floor jack under connecting point of the knuckle and lower arm A, and raise the suspension with the jack.

  1. Remove the wheel speed sensor harness bracket (A).

  1. Remove the upper arm mounting bolts (A), then remove the upper arm (B).
    NOTE: Use new mounting bolts during reassembly.
  1. Install the upper arm in the reverse order of removal, and note these items;
    • First install all the components, and lightly tighten the bolts and the 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 knuckle.
    • Before connecting the ball joint, degrease the threaded section and the tapered portion of the ball joint pin, the ball joint connecting hole, and the threaded section and the mating surfaces 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.
    • Rear disc brake type: After installing the brake caliper, make sure the clearance between lower arm B and parking brake cable is more than 5 mm (0.20 in.).
    • Before installing the wheel, clean the mating surfaces on the brake disc or the brake disc/drum and the inside of the wheel.
