12. REMOVE FRONT SUPPORT TO FRONT SHOCK ABSORBER NUT

(a) Using a piece of cloth, etc., clean the shock rod and remove any foreign matter and oil. NOTICE: Thoroughly clean the shock rod to prevent damage to the shock rod due to contact of foreign matter.

*a Cloth, etc. *b Shock Rod

(b) Attach SST (09727-58130) to SST (09727-58100). SST: 09727-58100 SST: 09727-58130 NOTICE: Check that there are no cracks or damage in SST (09727-58130) that could prevent it from securing the shock rod of the front shock absorber assembly LH. If there are, replace SST (09727-58130) with a new one.

*1 SST(09727-58100) *2 SST(09727-58130)

(c) Clean the surface of SST (09727-58130) to which the front shock absorber assembly LH is installed and remove any foreign matter and oil. NOTICE: Thoroughly clean the installation surface to prevent damage to the shock rod due to contact of foreign matter.

*a Installation Surface

(d) Using a long ball hexagon 5, install SST (09727-58100) and SST (09727-58130) to the shock rod. NOTICE: When installing SST (09727-58100) and SST (09727-58130), do not fold back the No. 1 front shock absorber dust cover LH in an improper direction and deform it. HINT: Install SST (09727-58100) and SST (09727-58130) to the base of the shock rod and check that SST (09727-58100) and SST (09727-58130) are securing the shock rod. The front shock absorber assembly LH has a built-in rebound spring and is constructed to constantly contract the shock rod. For this reason, it is difficult to sufficiently contract the coil spring to a level that frees the front suspension support sub-assembly LH using only the coil spring compressor (09727-30022), making it necessary for SST (09727-58100), SST (09727-58130) and a long ball hexagon 5 to be used to ensure a shock rod free length in which work can be performed with a small amount of compression.

(e) For SST with stopper pins:

(1) Secure SST in a vise.

SST: 09727-30022

09727-00010

09727-00022

09727-00031

(2) Attach the hooks of each SST arm across the diameter of the coil spring. CAUTION: Make sure that the hooks of the upper and lower arms are attached to the coil spring so that the distance between the hooks is as large as possible. Make sure that the arms of SST are parallel and attached to the coil spring, and the number of coil springs between the hooks on each side is the same. Check that the claws of the hooks are securely attached to the coil spring.

*a Correct *b Incorrect *c Parallel *d Not Parallel

(3) Install the stopper pins to the hooks of SST. CAUTION: Make sure that the stopper pins are installed securely.

*a Correct *b Incorrect *c Stopper Pin

(4) 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

(5) Using SST, compress the coil spring.

SST: 09727-00110

(6) 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 if the coil spring is not free.

(f) For SST without stopper pins:

(1) Secure SST in a vise. SST: 09727-30021 09727-00010 09727-00021 09727-00031

(2) Attach the hooks of each SST arm across the diameter of the coil spring. CAUTION: Make sure that the hooks of the upper and lower arms are attached to the coil spring so that the distance between the hooks is as large as possible. Make sure that the arms of SST are parallel and attached to the coil spring, and the number of coil springs between the hooks on each side is the same. Check that the claws of the hooks are securely attached to the coil spring.

*a Correct *b Incorrect *c Parallel *d Not Parallel

(3) Install SST and 2 vehicle nuts to the upper support as shown in the illustration. SST: 09727-30021 09727-00090 09727-00100

*a Vehicle Nut

(4) Using SST, compress the coil spring.

HINT:

Installing SST as shown in the illustration is recommended.

SST: 09727-00110

(5) 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 if the coil spring is not free.

13. REMOVE COLLAR

14. REMOVE FRONT SUSPENSION SUPPORT SUB-ASSEMBLY LH

15. REMOVE FRONT SPRING SEAT SUB-ASSEMBLY WITH INSULATOR LH

16. REMOVE FRONT COIL SPRING LH

(a) Remove SST from the front coil spring.

NOTICE:

17. REMOVE FRONT SPRING BUMPER LH

18. REMOVE FRONT COIL SPRING LOWER INSULATOR LH

19. REMOVE FRONT SHOCK ABSORBER ASSEMBLY LH

(a) Using SST (09727-58010), remove SST (09727-58100) and SST (09727-58130) from the front shock absorber assembly LH.

SST: 09727-58010

09727-58030

NOTICE:

Apply molybdenum grease to the bolt (area with diagonal lines) of SST (09727-58010).

Application Area

(1) Install SST (09727-58030) to the end of the shock rod of the front shock absorber assembly LH.[#1]

(2) Install SST (09727-58010) to the front shock absorber assembly LH.[#2]

NOTICE:

Take due care when installing SST (09727-58010) to ensure the shock rod is not damaged.

(3) Secure the SST (09727-58010) bolt and SST (09727-58030) with the fixing nut.[#3]

(4) After securing the SST (09727-58010) bolt, rotate the nut clockwise.[#4]

NOTICE:

Extend the shock rod until SST (09727-58100) and SST (09727-58130) separate from the shock absorber outer shell.

(5) Using a long ball hexagon 5, remove SST (09727-58100) and SST (09727-58130).[#5]

NOTICE:

If SST (09727-58100) and SST (09727-58130) are removed without using SST (09727-58010), the action of the rebound spring will cause the shock rod to contract suddenly. Therefore, remove SST (09727-58100) and SST (09727-58130) after securing the shock rod with SST (09727-58010).

(6) Using a piece of cloth, etc., clean the shock rod of the front shock absorber assembly LH and remove any foreign matter and oil.

NOTICE:

If the shock rod is expanded/contracted while foreign matter or oil are still present, it may damage the front shock absorber assembly LH or cause oil leaks.

(7) After securing the SST (09727-58010) bolt, rotate the nut counterclockwise.

(8) Check that the shock rod and SST (09727-58030) have become free before releasing the fixing nut and removing SST (09727-58010) from the shock rod.

NOTICE:

Take due care when removing SST (09727-58010) to ensure the shock rod is not damaged.

(9) Remove SST (09727-58030) from the end of the shock rod.

(10) Using a piece of cloth, etc., clean the end of the shock rod threads and remove any foreign matter and oil.
