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

*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.

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

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.

(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.
