Steering Gearbox Installation

  1. Before installing the steering gearbox, make sure that no power steering fluid is on the mating surface of the gearbox and the front suspension subframe. To prevent the gearbox mounting bolts from loosening after the installation, remove the power steering fluid from the mount cushions and bolt holes.
  2. Apply a mild soap and water solution to both sides of the mount cushion mating surfaces (A).

  3. Pass the cylinder of the steering gearbox (B) through the wheel well opening on the driver's side.
  4. Carefully move the steering gearbox toward the passenger's side until the pinion shaft clears the wheel well opening on the body.
  5. Rotate the steering gearbox so the pinion shaft (A) points upward.

  6. Continue moving the gearbox toward the passenger's side until the steering gearbox is in position. Make sure the power steering return line and inlet line are routed above the gearbox.
  7. Remove the vinyl tape from the pinion shaft, and install the pinion shaft grommet (A). Align the slot in the pinion shaft grommet with the lug portion (B) on the valve housing.

  25. Install the tie-rod end ball joint nut, and tighten it to the specified torque. Install the new cotter pin (B), and bend it as shown (C) or (D).
  26. Remove the engine hanger adapter, and the engine support hanger.
  27. Install the front wheel, then set the wheels in the straight ahead position.
    NOTE: Before installing the wheel, clean the mating surfaces of the brake disc and inside of the wheel.
  28. Lower the vehicle.
  29. Install the new cover seal (A) all the way around in the steering joint cover B. Make sure there are no wrinkles in the seal, then install the steering joint cover B.

  32. With the rack in the straight ahead driving position, cut the wire (D) and slip the lower end of the steering joint onto the pinion shaft (E).
  33. Align the bolt hole (A) on the steering joint with the groove (B) around the pinion shaft, and loosely install the joint bolt (C). Make sure the joint bolt is securely in the groove in the pinion shaft. Pull on the steering joint to make sure the steering joint is fully seated.

  36. Center the cable reel by first rotating it clockwise until it stops. Then rotate it counterclockwise (about three full turns) until the arrow mark on the label points straight up. Reinstall the steering wheel (see STEERING WHEEL INSTALLATION  ).
  37. Reconnect the negative battery cable to the battery, and do these tasks:
    • Turn the ignition switch ON (II); the SRS indicator should come on for about 6 seconds and then go off.
    • Enter the anti-theft code for the audio system and the navigation system (if equipped), then enter the client's audio presets.
    • Set the clock (on vehicles without navigation).
    • Make sure the horn and turn signal switches work properly.
    • Make sure the steering wheel switches work properly.
  38. Fill the system with power steering fluid, and bleed air from the system (see FLUID REPLACEMENT  ).
  39. After installation, do these checks:
    • Start the engine, allow it to idle, and turn the steering wheel from lock-to-lock several times to warm up the fluid. Check the gearbox for leaks (see FLUID LEAKAGE INSPECTION  ).
    • Check the steering wheel spoke angle.

      If steering spoke angles to the right and left are not equal (steeling wheel and rack are not centered), correct the engagement of the joint/ pinion shaft serrations.

    • Set the steering column to the center tilt position, and to the center telescopic position, then do the front toe inspection/adjustment (see WHEEL ALIGNMENT ).
