SST: 09727-00110

(e) 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.

(f) Align the end of the front coil spring with the flange of the front lower coil spring insulator and install the front coil spring.
