Adjustment Procedure


    Object Number: 451489  Size: SH

    Important: Perform the rack bearing preload adjustment with the front wheel raised and the steering wheel centered. Make sure the steering wheel is centered after adjustment.

  1. Loosen the adjuster plug lock nut (1).
  2. Turn the adjuster plug clockwise until the adjuster plug bottoms in the gear assembly.
  3. Turn the adjuster plug back 50 degrees to 70 degrees (approximately one flat).
  4. Install the adjuster plug lock nut (1) to the adjuster plug.
  5. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    Tighten
    Hold the adjuster plug stationary while tightening the adjuster plug lock nut (1) to 68 N·m (50 lb ft).
