J 45400 Strut Spring Compressor

Disassembly Procedure


    Object Number: 861361  Size: SH

    Caution: Strut spring is under a high compressive load. Do not remove the strut shaft to upper support nut without first relieving the upper and lower spring supports of spring pressure, using the proper spring compressing tool.

  1. Mount the J 45400 or equivalent in the holding fixture.
  2. Place the strut/spring assembly into the spring compressor. Fasten the strut with a strut-to-knuckle bolt and nut through the lower strut mounting hole.
  3. Compress the spring enough to completely unload the upper spring supports.

  4. Object Number: 861364  Size: SH
  5. Remove the strut shaft nut using a wrench, while holding the shaft with a TORX™ socket.

  6. Object Number: 861363  Size: SH
  7. Release the spring compressor and tilt the strut assembly outward.
  8. Remove the upper spring support. Inspect the rubber for cracks or deterioration.
  9. Remove the spring from the strut. Inspect the spring for damage.
  10. Remove the dust shield assembly. Inspect for cracks or deterioration.
  11. Remove the strut from the compressor. Extend and retract the strut shaft and inspect for smooth, even resistance.

Assembly Procedure

  1. Place the strut into the spring compressor. Fasten the strut with a strut-to-knuckle bolt and nut through the lower strut mounting hole.
  2. Extend the strut shaft to the limit of its travel.

  3. Object Number: 862654  Size: SH
  4. Place the dust shield assembly onto the strut assembly.
  5. Install the spring onto the strut.

  6. Object Number: 877474  Size: SH
  7. Install the upper strut mount onto the strut and spring.
  8. Important: Ensure that the springs are correctly positioned in their spring support seats.

  9. Compress the spring, guiding the strut shaft through upper mount until the upper washer and shaft nut can be installed. Do not over compress the spring.
  10. Notice: Refer to Fastener Notice in the Preface section.

  11. Tighten the strut shaft using a TORX™ socket, while holding the shaft nut with a wrench.
  12. Tighten
    Tighten the rear strut shaft nut to 50 N·m (37 lb ft).

  13. Release spring compressor tool.
  14. Remove strut from compressor.
