Notice: Use care when handling the coil springs in order to avoid chipping or scratching the coating. Damage to the coating will result in premature failure of the coil springs.
1. If servicing the driver side coil spring, perform the following:
1.1. Remove the brake master cylinder nuts.
1.2. Gently move the brake master cylinder to one side.
2. Remove the shock absorber upper mounting bolts (18) and nuts (17).
3. Raise and support the vehicle. Refer to Vehicle Lifting.
4. Remove the tire and the wheel. Refer to Tire and Wheel Removal and Installation.
5. Remove the stabilizer shaft link. Refer to Stabilizer Shaft Link Replacement.
6. Remove the shock absorber lower bolts (11) and nuts (3).
7. Remove and discard the lower control arm cotter pin (7).
8. Remove the lower control arm nut (8).
9. Using J 39549 separate the lower ball joint (10) from the steering knuckle (6).
10. Remove the lower control arm (12) and lower ball joint (10) from the steering knuckle (6).
Important: Use chalk or paint in order to mark (do not scribe) the lower mount location relative to the upper mount location before removing the shock absorber and coil spring.
11. Remove the shock absorber (13) and the coil spring (14) from the vehicle.
Disassembly Procedure
1. Install J 34013-88 to J 34013-B.
2. Install J 34013-114 to J 34013-B using the following mounting holes.
- For the driver-side shock absorber and coil spring:
- C-H (lower left corner)
- P (upper right corner)
- For the passenger-side shock absorber and coil spring:
- A-X-P (upper left comer)
- C-H (lower right corner)
Important: Align J 34013-114 and J 34013-88 so that these tools may open and close together. If J 34013-114 and J 34013-88 do not align properly, the tools will not open.
3. Install the shock absorber and coil spring to J 34013-114 and J 34013-88.
Important: Align the top of the shock absorber flat against J 34013- 114.
4. Install the driver side shock absorber (2) and coil spring (1) to the top of J 34013-114.
5. Install the passenger side shock absorber (2) and coil spring (1) to the top of J 34013-114.
6. Install the shock absorber (1) to J 34013-88.
7. Close J 34013-88 and install the locking pin.
Important: If the mounting ears of the shock absorber are not facing downward, toward the rear of J 34013-B, the shock absorber will not align properly.
8. Turn the screw on J 34013-B counterclockwise in order to raise the shock absorber up to J 34013-114. Align the top of the shock absorber flat against the tool with the studs going through the guide holes in J 34013-114.
Caution: Do not over compress the spring. Severe overloading may cause tool failure which could result in bodily injury.
9. Compress the coil spring approximately 13 mm (0.50 inch).
10. Insert J 39642 -1 on the shock absorber nut, then insert J 39642 -2 through J 39642-1 in order to hold the shock absorber rod in place.
11. Remove the shock absorber nut using J 39642-1 while holding the shock absorber rod from rotating with J 39642-2.
12. Discard the shock absorber nut.
13. Turn J 34013-B clockwise in order to fully relieve coil spring tension.
14. Remove the coil spring from the shock absorber.
Assembly Procedure
1. Install the coil spring to the shock absorber.
2. Position the upper and lower coil spring seats correctly.
Important: Align the top of the shock absorber flat against J 34013-114.
3. Install the shock absorber to the top of J 34013- 114.
Important: Only turn the screw until the shock absorber secures itself in J 34013-B. Do not load the coil spring.
4. Turn the screw on J34013-B counterclockwise in order to raise the shock absorber up to J 34013-114 without compressing the coil spring.
Important: Ensure that J 34013-115 is straight with the shock absorber.
5. Place J 34013-115 down through the top of J 34013-B to the top of the shock absorber.
Caution: Do not over compress the spring. Severe overloading may cause tool failure which could result in bodily injury.
6. Turn the operating screw clockwise in order to compress the coil spring until the threaded portion of the shock absorber rod is through the top of the shock absorber mount.
7. Remove J 34013-115.
Important: Always use a new shock absorber nut. Never reinstall the original nut.
8. Insert the new shock absorber nut on the shock absorber.
9. Place J 39642-1 on the shock absorber nut.
Notice: Turning the shock absorber while tightening the nut may damage the shock absorber. In order to prevent damage, keep the shock absorber in a stationary position while tightening the nut.
10. Insert J 39642-2 through J 39642-1 and tighten the shock absorber nut.
11. Tighten the shock absorber nut while holding onto J 39642-2.
12. Remove the shock absorber and coil spring from J 34013-B.
Installation Procedure
1. Align and install the shock absorber (13) and coil spring (14) to the lower control arm (12).
Notice: Refer to Fastener Notice in Service Precautions.
2. Install the shock absorber lower bolts (11) and nuts (3).
- Tighten the shock absorber lower nuts (3) to 65 Nm (48 ft. lbs.).
3. Align and Install the lower ball joint (10) to the steering knuckle (6).
4. Install the lower ball joint nut (8).
- Tighten the lower ball joint nut (8) to 110 Nm (81 ft. lbs.).

5. Install the new lower ball joint cotter pin (7).
6. Install the stabilizer shaft link. Refer to Stabilizer Shaft Link Replacement.
7. Install the tire and the wheel. Refer to Tire and Wheel Removal and Installation.
8. Lower the vehicle.
9. Install the shock absorber upper mounting bolts (18) and nuts (17).
- Tighten the shock absorber upper mounting nuts (17) to 41 Nm (30 ft. lbs.).

10. If servicing the driver side shock absorber, perform the following:
10.1. Gently, reposition the brake master cylinder into position.
10.2. Install the brake master cylinder nuts.
- Tighten the brake master cylinder nuts to 29 Nm (21 ft. lbs.).
