INSTALLATION

CAUTION / NOTICE / HINT

HINT:

  • Use the same procedure for the RH side and LH side.
  • The following procedure is for the LH side.

PROCEDURE

1. INSTALL FRONT LOWER COIL SPRING INSULATOR

(a) Install the front lower coil spring insulator to the front shock absorber assembly.

Positioning Pin

NOTICE:

When installing the front lower coil spring insulator, insert the positioning pin of the spring seat into the hole of the front lower coil spring insulator.

2. INSTALL FRONT SPRING BUMPER

(a) Install the front spring bumper to the front shock absorber assembly.

3. INSTALL FRONT COIL SPRING

(a) Secure SST in a vise.

SST: 09727-30022

09727-00010

09727-00022

09727-00031

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

CAUTION:

  • Do not perform the work without checking to make sure that the claws of the hooks are securely engaged.

    Front Coil Spring Diameter
  • It could cause the hook to slip off and the spring to fly out, which could result in an injury.
  • Do not install SST to the front coil spring unless its top and bottom hook distance is set to the widest condition.
  • It could cause the hook to slip off and the spring to fly out, which could result in an injury.
  • Do not install SST when the distances between the SST arms or the number of coils of the coil spring between the hooks are not the same.
  • It could cause the hook to slip off and the spring to fly out, which could result in an injury.

(c) Install the stopper pins to the hooks of SST.

CAUTION:

  • Do not perform the work if the stopper pin is not securely installed.
  • It could cause the hook to slip off and the spring to fly out, which could result in an injury.

(d) Using SST, compress the front coil spring.

CAUTION:

  • While compressing the spring, if the front coil spring starts to bend into a bow shape, do not continue the work.
  • It could cause the hook to slip off and the spring to fly out, which could result in an injury.
  • Do not compress the springs so far that the coils of the springs touch each other.
  • It could cause the hook to slip off and the spring to fly out, which could result in an injury.
  • Do not use an impact wrench.
  • The threads may be stripped, or the sudden compression may result in slack that causes the hooks to slip off, causing the spring to fly out and possibly 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 stopper pin is removed, install a coil spring stopper belt as shown in the illustration.
  • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

SST: 09727-00110

(e) Install the front coil spring to the front shock absorber assembly.

NOTICE:

Make sure to fit the end of the front coil spring that has the smaller diameter into the depression of the front lower coil spring insulator.

4. INSTALL FRONT UPPER COIL SPRING INSULATOR

(a) Install the front upper coil spring insulator to the front No. 1 shock absorber dust cover so that the positioning tab of the front upper coil spring insulator is aligned with the positioning indentation of the front No. 1 shock absorber dust cover.

(b) Remove SST from the front coil spring.

NOTICE:

  • Check that front coil spring is installed so that it is aligned with the level difference of front lower coil spring insulator.
  • Do not use an impact wrench. It will damage SST.

10. CONNECT FRONT NO. 1 SHOCK ABSORBER DUST COVER

(a) Connect the end of the front No. 1 shock absorber dust cover with the claws of the front shock absorber with coil spring.

NOTICE:

  • Make sure that the end of the front No. 1 shock absorber dust cover is securely attached to the claws of the front shock absorber with coil spring.
