6. LOOSEN FRONT SUPPORT TO FRONT SHOCK ABSORBER NUT

(a) Temporarily install the 2 nuts to the front shock absorber assembly.

(b) Loosen the front support to front shock absorber nut.

CAUTION:

Only loosen the front support to front shock absorber nut if the front shock absorber with coil spring needs to be disassembled.
Only loosen the front support to front shock absorber nut, do not remove it.
If the front support to front shock absorber nut is removed with the front coil spring under tension, components of the front shock absorber with coil spring may fly off.

7. SEPARATE FRONT STABILIZER LINK ASSEMBLY

(a) Remove the cap.

(b) Remove the nut and separate the front stabilizer link assembly from the front shock absorber assembly.

NOTICE:

Do not damage the boot of the ball joint.

HINT:

If the ball joint turns together with the nut, use a 6 mm hexagon socket wrench to hold the stud bolt.

8. SEPARATE FRONT SPEED SENSOR

(a) Remove the bolt, disengage the clamp and separate the front speed sensor and front flexible hose from the front shock absorber assembly.

NOTICE:

Be sure to separate the front speed sensor and front flexible hose from the front shock absorber assembly completely.

9. REMOVE FRONT SHOCK ABSORBER WITH COIL SPRING

(a) Support the front lower No. 1 suspension arm sub-assembly using a jack and wooden block.

*a	Wooden Block
*b	Jack
	Front of the Vehicle
	Wooden Block Placement Location

NOTICE:

Keep the front lower No. 1 suspension arm sub-assembly supported until installation of the front shock absorber with coil spring is complete.

(b) Remove the 2 bolts and 2 nuts, and separate the front shock absorber with coil spring (lower side) from the steering knuckle.

NOTICE:

When removing the nuts, keep the bolts from rotating.
Use wire or an equivalent tool to hang the separated steering knuckle.

10. REMOVE FRONT SUPPORT TO FRONT SHOCK ABSORBER NUT

(a) Secure SST in a vise.

SST: 09727-00051

SST: 09727-30022

09727-00010

09727-00031

SST: 09727-00040

*a	SST(09727-00051)
*b	SST(09727-00040)
*c	SST(09727-30022 (09727-00010, 09727-00031))

(b) Attach the hooks of each SST arm across the diameter of the coil spring.

CAUTION:

Make sure that the hooks are securely attached to the coil spring.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Make sure that the hooks of the upper and lower SST arms are attached to the coil spring so that the distance between the hooks is as large as possible.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Make sure that the arms of SST are parallel and the number of coils between the arms is the same on each side.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

CAUTION:

Make sure that the stopper pins are installed securely.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

(d) Install SST and 2 vehicle nuts to the upper support as shown in the illustration.

SST: 09727-30022

09727-00090

09727-00100

*a	Vehicle Nut

(e) Install SST as shown in the illustration.

CAUTION:

The pin is not attached to one side, so be sure to hang the belt.

SST: 09727-00110

(f) Using SST, compress the coil spring.

CAUTION:

If the coil spring starts to bow out while using SST, stop immediately and reattach SST correctly.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Do not compress the coil spring to the point where the coils touch each other.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
Do not use an impact wrench.
If an impact wrench is used, the threads of SST may be damaged, or sudden compression of the coil spring may cause a hook to disengage and the coil spring to fly out, resulting in injury.
If a stopper pin touches the coil spring while using SST, remove the stopper pin and continue with the procedure.
If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

(g) Check that the coil spring has become detached, and then remove the front support to front shock absorber nut.

CAUTION:

Do not remove the front support to front shock absorber nut while the coil spring is under tension.
If the front support to front shock absorber nut is removed with the coil spring under tension, components of the front shock absorber with coil spring may fly off, resulting in injury.
