        • SST: 09727-58100 
        • SST: 09727-58130 
        NOTE:

        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.

        If there are, replace SST (09727-58130) with a new one.

        NOTE:

        Thoroughly clean the installation surface to prevent damage to the shock rod due to contact of foreign matter.

      6. Using a long ball hexagon 5, install SST (09727-58100) and SST (09727-58130) to the shock rod.
        GTY975524Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        NOTE:

        When installing SST (09727-58100) and SST (09727-58130), do not fold back the front spring seat sub-assembly with insulator 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 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 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.

    2. Secure SST in a vise.

    3. Attach the hooks of each SST arm across the diameter of the coil spring.
      WARNING:
      • Make sure that the hooks are securely attached to the coil spring.
        GTY600271Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • 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.
        GTY628080Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • 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.
        GTY596482Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
    4. Install the stopper pins to the hooks of SST.
      WARNING:
      • 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.

    6. Using SST, compress the coil spring.
      WARNING:
      • If the coil spring starts to bow out while using SST, stop immediately and reattach SST correctly.
        GTY628386Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • 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.
        GTY628385Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
      • Do not use an impact wrench.
        GTY628081Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • 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.
        GTY626281Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      • 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 
    7. Check that the coil spring has become detached, and then remove the front support to front shock absorber nut.
      WARNING:
      • 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.

      Application Area
      1. Install SST (09727-58030) to the end of the shock rod of the front shock absorber assembly.[#1]
      2. Install SST (09727-58010) to the front shock absorber assembly.[#2]
        NOTE:

        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]
        NOTE:

        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]
        NOTE:

        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 and remove any foreign matter and oil.
        NOTE:

        If the shock rod is expanded/contracted while foreign matter or oil are still present, it may damage the front shock absorber assembly 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 end of the shock rod.
        NOTE:

        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.
