Removal Procedure

Tools Required

    • J 3289-20 Holding Fixture
    • J 34013-B Strut Compressing Tool
    • J 34013-20 Dampener Rod Clamp
    • J 34013-27 Alignment Rod

    Notice: Care should be taken to avoid scratching or cracking the spring coating when handling the front suspension coil spring. Damage can cause premature failure.


    Object Number: 143999  Size: SH
  1. Mount the J 34013-B and theJ 3289-20 .
  2. Mount the strut (1) into the J 3289-20 . Take notice that the J 34013-B has the strut mounting holes drilled for a specific car line.

  3. Object Number: 201158  Size: SH
  4. Compress the strut approximately ½ the height after the initial contact with the cap. Do not bottom the spring (1) or dampen the rod.

  5. Object Number: 175813  Size: SH
  6. Remove the nut (2) from the strut the dampener shaft.

  7. Object Number: 201170  Size: SH
  8. Place the J 34013-27 on top of the dampen shaft.
  9. Use this rod to guide the dampen shaft straight down through the bearing cap while decompressing the spring (1).

  10. Remove the components 1 through 10.

Installation Procedure

    Notice: Care should be taken to avoid scratching or cracking the spring coating when handling the front suspension coil spring. Damage can cause premature failure.


    Object Number: 189500  Size: SH
  1. Install the bearing cap if the cap was previously removed from the top of the strut (8).

  2. Object Number: 144008  Size: SH
  3. Mount the strut into the J 34013-B using the bottom locking pin only.
  4. Extend the dampener shaft (1) and install the J 34013-20 onto the dampener shaft.

  5. Object Number: 189500  Size: SH
  6. Install the spring (6) over the dampener.

  7. Object Number: 144008  Size: SH
  8. Swing the assembly up in order to install the upper locking pin (2).

  9. Object Number: 189500  Size: SH
  10. Install the upper insulator (5).
  11. Install the shield (10). Install the bumper (9).
  12. Install the upper spring seat.

  13. Object Number: 201158  Size: SH

    Important: The flat on the lower spring seat is NOT perpendicular to the strut/knuckle opening.

  14. Face the upper spring seat flat in the same direction as the centerline of the strut/knuckle assembly spindle.
  15. Install the J 34013-27 .
  16. Turn the forcing screw (3) while the J 34013-27 centers the assembly.

  17. Object Number: 175813  Size: SH
  18. Remove the J 34013-27 and install the nut (2) when the threads on the dampen shaft are visible.
  19. 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.

  20. Tighten the nut (2).
  21. Tighten
    Tighten the nut to 70 N·m (52 lb ft).

  22. Use a line wrench (1) while holding the dampen shaft with the socket.

  23. Object Number: 144008  Size: SH
  24. Remove the clamp Use the J 34013-20 .
