  7. Remove the dust cap (1).
  8. Remove the strut rod piston nut (2).
  9. Release the compressed spring (10).
  10. Remove the strut assembly from the J 34013-B
  11. Remove the following components from the strut:
  12. 9.1. The strut mount (3)
    9.2. The dust seal (4)
    9.3. The spring seat (5)
    9.4. The upper insulator (6)
    9.5. The coil spring (10)
    9.6. The spring bumper (7)
    9.7. The lower insulator (9)

Installation Procedure


    Object Number: 238038  Size: SH

    Notice: Care should be taken to avoid chipping or cracking the spring coating when handling the front suspension coil spring. Failure to observe this notice may result in spring breakage.

    Important: Make sure that the spring seat "flat spot" faces outboard toward the strut mounting bracket, while the strut mount "flat spot" faces inboard away from the strut mounting bracket , when assembling the unit.

  1. Install the following components to the strut:
  2. 1.1. The lower insulator (9)
    1.2. The spring bumper (7)
    1.3. The coil spring (10)
    1.4. The upper insulator (6)
    1.5. The spring seat (5)
    1.6. The dust seal (4)
    1.7. The strut mount (3)

    Object Number: 143233  Size: SH
  3. Mount the strut assembly into the J 34013-B using the J 34013-88 .

  4. Object Number: 777001  Size: SH
  5. Identify the orientation of the spring seat (1), the strut mount (3) , then 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 and hold the strut rod, at the top, from turning.
  8. Tighten
    Tighten the strut rod piston nut (2) to 75 N·m (55 lb ft).

  9. Install the dust cap (1).
  10. Release the compressed coil spring.

  11. Object Number: 143233  Size: SH
  12. Remove the strut (2) from the J 34013-B .
  13. Install the strut assembly. Refer to Strut Assembly Replacement .
