Installation Procedure


    Object Number: 238024  Size: SH
  1. Move the stabilizer shaft from the left side of the vehicle toward the center of the vehicle in order to install the stabilizer shaft to the vehicle.
  2. Use a jack in order to raise the suspension crossmember (2).
  3. 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.

  4. Secure the suspension crossmember with 6 bolts.
  5. Tighten

        • Tighten the outer rear suspension crossmember bolts to 74 N·m (55 lb ft).
        • Tighten the inner rear suspension crossmember bolts to 19 N·m (14 lb ft).
  6. Remove the jack from the suspension crossmember.
  7. Reconnect the following hoses:
  8. • The ORVR hoses to the EVAP canister
    • The filler neck vapor hoses to the fuel tank
    • The filler neck hose to the fuel tank
  9. Install the right and left fuel tank bands. Secure the right and left fuel tank bands using 1 bolt (1) for each band.
  10. Tighten
    Tighten the bolts to 39 N·m (29 lb ft).

  11. Remove the support from the fuel tank.

  12. Object Number: 238023  Size: SH
  13. Install the 2 stabilizer shaft insulators (1) to the stabilizer shaft. Align the matchmarks.
  14. Important: The weight of the vehicle must be on the tires and wheels before tightening the nuts or the bolts.

  15. Install the right and left stabilizer shaft insulator clamps. Secure the right stabilizer shaft insulator clamp using 2 bolts. Secure the left stabilizer shaft insulator clamp using 2 bolts.

  16. Object Number: 238047  Size: SH
