        *a	Front Coil Spring Diameter

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

      • It could cause the hook to slip off and the spring to fly out, which could result in an injury.

      • Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

        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.
   3. Install the stopper pin to the hook of SST.
      WARNING:

      • Check that the stopper pin is securely installed.
      • It could cause the hook to slip off and the front coil spring LH to fly out, which could result in an injury.

   4. Using SST, compress the coil spring.
      • SST: 09727-00110 
      WARNING:

      • Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

        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.

        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.

      • Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

        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.

      • Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

        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 SST as shown in the illustration.

      • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.
