  Q: How to service and repair the Leaf Spring Shackle on GMC Savana 3500?

  A:

  Service and repair of the shackle begins by elevating the vehicle to a hoist then using a suitable jack stand to stabilize the rear axle as this allows the rear springs to relax. First disconnect the tire and wheel before taking out both retaining bolts from the shackle assembly. Next remove the shackle from the vehicle. Install the shackle on the vehicle by first placing it back in position then tightening a new lower retaining bolt with new nut followed by tightening a new upper retaining bolt with another new nut until both reach a torque level of 90 nm (67 ft. Lbs.). After properly resetting the tire and wheel you must lower the vehicle.

  Q: How to replace the Leaf Spring Shackle on GMC Savana 3500?

  A:

  The installation of a new spring shackle starts with raising and supporting the vehicle before using a safety stand to support the rear axle. The first procedure requires you to remove both the mounting nut and bolt which attach the spring shackle to the Leaf Spring then proceed with removing the mounting nut and bolt which attach the spring shackle to the frame bracket. Replace the spring shackle by installing it onto the Leaf Spring along with the frame bracket then secure it with mounting nut and bolt without applying torque. The spring shackle installation requires you to use the mounting nut and bolt to connect it to the Leaf Spring . Perform this operation according to the fastener notice in service precautions while tightening the nuts to 90 nm (66 ft. Lbs.). The last procedure is to take off the rear axle support before lowering the vehicle.
