Knuckle/Hub Replacement

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise the vehicle on a lift (see LIFT AND SUPPORT POINTS ).
  2. Remove the wheel nuts and the front wheel.

  4. Remove the brake caliper bracket mounting bolts (B), then 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.
  5. Pry up the stake (A) on the spindle nut (B), then remove the nut.

  6. Remove the front brake disc (see FRONT BRAKE DISC REPLACEMENT ).
  7. Check the front hub for damage and cracks.
  8. Remove the wheel speed sensor (A) from the knuckle (B). Do not disconnect the wheel speed sensor connector.

  9. 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.

  10. Disconnect the tie-rod end ball joint from the knuckle using the ball joint remover (see BALL JOINT REMOVAL ).
  11. 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.

  12. Disconnect the lower ball joint from the knuckle using the ball joint remover (see BALL JOINT REMOVAL ).
    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.
  13. 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.

  14. Pull the knuckle (C) outward, and separate the outboard joint (D) from the front hub using a plastic hammer.
    NOTE:
    • Do not pull the driveshaft end outward. The driveshaft inboard joint may come apart.
    • During installation, apply grease to the mating surfaces of the wheel bearing and the driveshaft outboard joint (see step 1 under DRIVESHAFT INSTALLATION ).
  15. 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.
  16. Check the wheel alignment, and adjust it if necessary (see WHEEL ALIGNMENT ).
