Instructions for Installation of New Shackles

1. Lower the jack. Allow the suspension to droop so that it will take the weight of the vehicle off of the shackle. This will keep the shackle from binding, and it facilitates the removal of the mounting bolts.
2. Disconnect the lower mounting bolt from the shackle and the spring by using a socket and ratchet. Lower the axle so that the spring drops completely out of the shackle.
3. Remove the mounting bolt, and remove the shackle from the frame. If the bolt has been on there for a long time, it may be necessary to use a dead blow hammer to force it to become loose.
4. Position the new shackle on the frame. Insert the mounting bolt, and allow the bolt to remain loose. Later, the shackle can be moved around to help align both the shackle and spring.
5. Lift the rear axle by using the jack. Align the spring eye with the shackle. Slowly insert the spring into the shackle. Raise the jack a little at a time just until the holes on the shackle and the spring eye line up.
6. Install the mounting bolt directly through the shackle and the spring. Tighten the bolts by using a ratchet and socket.
