Assembly Procedure


    Object Number: 382102  Size: SH
  1. Install the following components to the strut:
  2. • The lower insulator (8)
    • The rear spring (9)
    • The strut bumper (6)
    • The strut mount (5)
    • The strut insulator (3)

    Object Number: 143233  Size: SH
  3. Mount the strut assembly into the J 34013 using the J 34013-88 .
  4. Caution: Do not over compress the spring. Severe overloading may result in tool failure which could result in bodily injury.

  5. Compress the coil spring.
  6. 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.

  7. Install the strut rod piston nut.
  8. Tighten
    Tighten the strut rod piston nut to 49 N·m (36 lb ft).

  9. Release the compressed coil spring. Remove the compressed coil spring from theJ 34013 .
  10. Install the strut to the vehicle. Refer to Strut Assembly Replacement .
