  8. Remove the insulator clamp bolts.
  9. Remove the insulator clamps.
  10. Remove the stabilizer shaft.
  11. Remove the insulators from the stabilizer shaft.
  12. Inspect all of the parts for wear and damage.

Installation Procedure


    Object Number: 164992  Size: SH
  1. Install the insulators on the stabilizer shaft. Position the slit on the insulator toward the front of the vehicle.

  2. Object Number: 178931  Size: SH
  3. Install the stabilizer shaft and the clamps.
  4. 2.1. Mount the stabilizer shaft with the identification facing on the right side of the vehicle.
    2.2. Install the offset in the stabilizer shaft in the downward position.
    2.3. Position the insulators squarely in the clamps.
    2.4. Install the insulator clamp bolts in the proper holes.

    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.

  5. Install the following stabilizer link parts in position:
  6. • The retainers
    • The insulators
    • The link
    • The spacers
    • The bolts
    • The nuts

    Tighten

        • Tighten the clamp bolts to 36 N·m (27 lb ft)
        • Tighten the link nut to 17 N·m (13 lb ft).
  7. Install the tire and wheel assembly. Refer to Wheel Installation in Tires and Wheels.
  8. Lower the vehicle.

  14. Inspect all of the parts for wear and damage.

Installation Procedure

  1. Install the insulators to the stabilizer shaft. Make sure the slit in the insulator faces forward.
  2. Install the stabilizer shaft to the frame and the lower control arm. In order to allow alignment of the control arm to stabilizer shaft insulator clamp holes, unload the torsion bar. Refer to Torsion Bar Replacement .
  3. Install the clamps to the insulators, and then to the frame.

  4. Object Number: 178931  Size: SH
  5. Install the insulator clamp bolts (right hand).

  6. Object Number: 178930  Size: SH
