REMOVAL PROCEDURE- Tools Required
- J 34013-B Strut Spring Compressor.
- J 34013-20 Damper Rod Clamp.
- J 34013-197.
- J 34013-125 Upper Strut Adapter.

DISASSEMBLE PROCEDURE
1. Install the strut to the J 34013-B. Use wing nuts to secure the tool to the mounting holes C and E/K. Position the wide end of the adapter outboard.
2. Install the J 34013-971 and the J 34013-125.
IMPORTANT: Align the J 34013-971 and the J 34013-125 so that the tools may open and close together. The tools will not open If the tools do not align properly.
3. Install the strut to the top of the J 34013-B.
4. Install the strut into the J 34013-971 and the J 34013-125.
5. Close the J 34013-971 and the J 34013-125.
6. Install the locking pins through the holes of J 34013-B and the struts mounting holes.
7. Turn the screw (1) on the J 34013-B counterclockwise to raise the strut up to the J 34013-125.
8. Compress the spring approximately 13 mm (0.50 in) or three to four complete turns of the operating screw.
CAUTION: Do not over compress the spring. Severe overloading may cause tool failure which could result in bodily injury.
9. Insert the J 42991 on the nut.
10. Hold shaft with a T-45 Tory bit.
11. Use the J 42991 to remove the nut while preventing the rod from rotating with a T-45 Tory bit.
12. Discard the strut nut.
13. Turn the operating screw (3) on the J 34013-B clockwise to fully relieve the spring compression.
14. Remove the spring (1).
ASSEMBLE PROCEDURE
1. Install the spring to the strut. Ensure to position the upper and lower spring seats correctly.
2. Install all the other components to the strut.
3. Turn the operating screw (3) on the J 34013-B counter-clockwise in order to raise the strut up.
4. Fully extend the strut shaft.
5. Attach the J 34013-20. This prevents the shaft from retracting during compression.
IMPORTANT: Align the J 34013-197 straight with the strut. If the J 34013-197 is not aligned, repeat steps 1 through 12 until the tool is straight.
6. Insert the J 34013-197 down through the top of the J 34013-B and onto the shaft.
7. Slowly turn the operating screw (3) counterclockwise in order to compress the spring until the threaded portion of the strut shaft is through the top of the strut.
CAUTION: Do not over compress the spring. Severe overloading may cause tool failure which could result in bodily injury.
NOTICE: Keep the strut rod in a stationary position when you tighten the strut nut. Turning the strut rod may damage the strut.
8. Insert a new strut nut on the strut rod.
NOTICE: Refer to Fastener Notice in Service Precautions.
9. Place the J 42991 on the shock absorber nut.
- Tighten the shock absorber rod to upper mount to 75 Nm (55 ft. lbs.).
10. Insert a T-45 torx(R) in place of J 34013-197.
11. Tighten the shock absorber nut while holding the shaft with a T-45 torx(R).
12. Remove the following tools from the J 34013-B:
12.1. Remove the J 34013-20.
12.2. Remove the J 34013-197.
12.3. Remove the J 42991.
13. Remove the strut from the J 34013-B.
INSTALLATION PROCEDURE
1. Install strut to vehicle. Refer to Strut Assembly Replacement.
2. Adjust the rear wheel alignment. Refer to Wheel Alignment Specifications (Rear Suspension) in Alignment.
