Installation Procedure

    Object Number: 227947 Size: SH

    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.

  1. Make a cardan joint notch correction(s) at this time if the steering column was determined to be misaligned (more than 5 degrees) from the steering wheel centerline.
  2. Otherwise follow the alignment marks on the cardan joint (1) and the steering gear input shaft.
  3. Position the cardan joint on to the steering gear.
  4. Install the cardan joint washer and the bolt (2).

    5. Tighten
    Tighten the cardan nut to 61N·m  (45 lb ft).
