Knuckle/Hub Replacement
  1. Remove the wheel nuts (A) and the front wheel.

  1. Remove the brake hose mounting bolt (A) from the damper bracket.
  1. 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 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. Raise the stake (A), then remove the spindle nut (B).
  1. Check the front hub for damage and cracks.

  1. Remove the wheel speed sensor (A) from the knuckle (B). Do not disconnect the wheel speed sensor connector.

  1. Remove the cotter pin (A) from the tie-rod end ball joint, then remove the nut (B).
    NOTE: During installation, install the new cotter pin after tightening the nut, and bend its end as shown.

  1. Remove the lock pin (A) from the lower 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.
    • Do not force or hammer on the lower arm, or pry between the lower arm and the knuckle. You could damage the ball joint.

  1. Remove the damper pinch bolts (A) and the self-locking nuts (B) from the damper.
    NOTE: Use new damper pinch bolts and new self-locking nuts during reassembly.
  1. Remove the driveshaft outboard joint (C) from the knuckle (D) by tapping the driveshaft end (E) with a soft face hammer while drawing the hub outward, then remove the knuckle/hub.
    NOTE:
  1. Install the knuckle/hub 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. Do not place the jack against the ball joint of the lower arm.
    • 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.
    • 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 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.

Wheel Bearing Replacement
  1. Separate the hub (A) from the knuckle (B) using the hub dis/assembly tool and a hydraulic press. Hold the knuckle with the attachment (C) of the hydraulic press or equivalent tool. Be careful not to damage or deform the splash guard (D). Hold onto the hub to keep it from falling when pressed clear.

  1. Press the wheel bearing inner race (A) off of the hub (B) using the hub dis/assembly tool, a commercially available bearing separator (C), and a press.

  1. Remove the splash guard (A) and the snap ring (B) from the knuckle (C).

  1. Press the wheel bearing (A) out of the knuckle (B) using the bearing driver attachment, the driver handle, and a press.
  1. Wash the knuckle and the hub thoroughly in high flash point solvent before reassembly.

  1. Press a new wheel bearing (A) into the knuckle (B) using the old bearing (C), a steel plate (D), the support base, and a press.
    NOTE:
    • Install the wheel bearing with the wheel speed sensor magnetic encoder (E) (brown color), toward the inside of the knuckle.
    • Remove any oil, grease, dust, metal debris, and other foreign material from the encoder surface.
    • Keep any magnetic tools away from the encoder surface.
    • Be careful not to damage the encoder surface when you insert the wheel bearing.

  1. Install the snap ring (A) securely in the knuckle (B).
  1. Install the splash guard (C), and tighten the screws (D) to the specified torque value.

  1. Install the hub (A) onto the knuckle (B) using the bearing driver attachment, the driver handle, the support base, and a hydraulic press. Be careful not to damage the splash guard (C).
