  1. Position the NEW steering knuckle king pin bushing (1) in the steering knuckle. Ensure the bushing is oriented correctly.
  2. Install the correct EN-46109  guide pin (2) in the steering knuckle king pin bolt hole.
    3. NOTE:
    • The EN-46109  guide pin has some play in it. An open end wrench can be used on the steering knuckle king pin to ensure the king pin remains centered over the guide pin.
    • Ensure the EN-46109  guide pin can be turned freely while pressing in the steering knuckle king pin. If the king pin makes contact with the guide pin, use the open end wrench to turn it slightly to regain the necessary clearance.
  3. Install the steering knuckle king pin (3) over the guide pin and into the steering knuckle king pin bushing (1). Ensure the king pin bolt hole is centered on the guide pin and lightly tap the king pin with a hammer to drive it through the king pin bushing until it starts to enter the steering knuckle bore.

    NOTE:
    • The intent of the CH-51692  knuckle support and CH-51692-10  support bar is to hold the steering knuckle in position in the hydraulic press so the king pin remains exactly vertical during installation.
    • The CH-51692-10  support bar is also equipped with several cutouts to accommodate all versions of HiPer Strut steering knuckles.
    • A suitable piece of steel bar stock measuring 25mm (1 in) x 51mm (2 in), and long enough to straddle the hydraulic press, can be used in place of the CH-51692-10  support bar.
  4. Place the steering knuckle (1) along with the CH-51692  knuckle support (2), CH-51692-10  support bar (3) onto a hydraulic press with the steering knuckle king pin axis exactly vertical with the hydraulic press piston. The CH-51692-10  support bar should be positioned with its hanging hole (4) positioned to the outside of the steering knuckle where the front wheel bearing and hub assembly mounts.

  5. Continue to press the steering knuckle king pin until the king pin is fully seated. The EN-46109  guide pin should be able to move freely at all times during the pressing to ensure proper alignment of the king pin with the king pin bolt hole.
  6. Once the steering knuckle king pin is fully seated, remove the steering knuckle from the hydraulic press and remove all of the special tools.
