        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.

        Do not install SST to the rear 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.

   1. Install the stopper pins to the hooks of SST.
      WARNING:

      • 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.

   2. Using SST, compress the coil spring.
      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.

        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 SST as shown in the illustration.

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

   End of Rear Upper Coil Spring Insulator LH

   1. Turn the rear support assembly suspension LH 120° or more to engage the end of the rear upper coil spring insulator LH to the rear shock absorber assembly LH claws.
      NOTE:

      • Make sure that the end of the rear upper coil spring insulator LH is engaged securely to the 3 rear shock absorber assembly LH claws.
      • Be careful not to deform the bellows of the rear upper coil spring insulator LH.
      • Keep the rear upper coil spring insulator LH free of oil and grease.
   2. Temporarily tighten a new lock nut.

   1. Install the rear wheel.
   2. Lower the vehicle and bounce it up and down several times to stabilize the rear suspension.
   3. Remove the rear wheel.
   4. Jack up the axle carrier with a wooden block between the jack and axle carrier. Apply a load to the rear suspension so that the rear No. 2 suspension arm assembly LH becomes level.
      WARNING:

      • Do not raise the jack up too high.
      • The vehicle could fall, resulting in a serious accident.
