Spring Shackle, Rear

The first step to change the spring shackle involves proper support and elevation of the vehicle. The procedure for replacing 2-door utility components requires Fuel Tank removal together with evap canister extraction and possibly spare tire elimination. After disconnecting the rear exhaust hangers you should lower the exhaust system when necessary before supporting the rear axle. Begin by removing the frame and Leaf Spring mounting bolts and respectively continue by taking out the spring shackle from the vehicle. Start by attaching the spring shackle to the vehicle before hooking it to the Leaf Spring mounting bolt while keeping the nut loose. To install the frame the spring shackle mounting bolt and nut requires attachment without application of torque. Use the axle support to elevate the component until the distance between the tube and bumper bracket metal surface reaches 164 - 176 mm (6.46 - 6.94 inch). Follow up by removing the rear axle support after tightening spring shackle mounting nuts to 122 nm (89 ft. Lbs.). Follow the process by raising the exhaust system if needed and reattaching the rear exhaust hangers then reinstall the spare tire followed by the evap canister for 2-door utilities and the Fuel Tank for 2-door utilities before lowering the vehicle.

Starting the spring shackle replacement requires that you lift the vehicle properly and install support. Two door utility owners should first remove the Fuel Tank and the evap canister followed by the spare tire if they need to access the spring shackle. Begin by removing the exhaust hangers at the back and lowering the exhaust system according to need. The rear axle needs proper support. The first step is to remove the frame to spring shackle mounting nut and bolt followed by leaf spring to spring shackle mounting nut and bolt then pull the spring shackle from the vehicle. First secure the spring shackle onto the vehicle frame where it needs to be installed before attaching it to both leaf spring mounting bolt and frame while leaving the bolts untightened. Place the frame onto the spring shackle mounting bolt and nut before avoiding nut and bolt tightening. The axle support should be raised until the metal material of the bumper bracket stands 164 - 176 mm (6.46 - 6.94 inch) away from the axle tube. First tighten the spring shackle mounting nuts to 122 nm (89 ft. Lbs.) before taking the rear axle support out of position. Raise your exhaust system if needed then reconnect rear exhaust hangers before you put back the spare tire followed by the evap canister for 2-door utilities and complete with the Fuel Tank for 2-door utilities before lowering the vehicle.

Service or repair begins by properly supporting the vehicle and also the rear axle. Spare tires on pickups and 4-door utility models need removal together with the disconnecting of the rear exhaust hangers before dropping the exhaust system. Service teams must eliminate the Fuel Tank together with evap canister for service work on 2-door utility models. Start by unscrewing the frame to spring shackle nut while removing washers followed by frame to spring shackle bolt, then disconnect the spring shackle to leaf spring nut along with washers before extracting the shackle from the vehicle. Reinstall the spring shackle on the vehicle before adding the spring shackle to leaf spring bolt and washers and finishing with spring shackle to leaf spring nut without tightening it. Set the frame to spring shackle bolt alongside washers and frame to spring shackle nut in their proper position before you will tighten. Support the axle section so it stands 6.46 inch to 6.94 inch away from the bumper bracket metal surface and apply 122 nm (89 ft. Lbs.) of torque to the spring shackle nuts. Two-door utility models require the evap canister and Fuel Tank reinstallation before continuing with installation. After raising the exhaust system install the rear exhaust hangers if required and replace the spare tire for pickups and 4-door utility models if they need it. End the task by taking off the rear axle support followed by lowering the vehicle.

The first step to replace the spring shackle begins with vehicle lifting and proper support of the vehicle's frame. The Fuel Tank and evap canister and spare tire should be removed from two-door utilities before installation. The rear exhaust hangers need removal before lowering the exhaust system and placing rear axle support. First disconnect the frame to spring shackle mounting nut and bolt then remove the Leaf Spring to spring shackle mounting nut and bolt before taking out the spring shackle from the vehicle. Put the spring shackle on the vehicle then connect and tighten the Leaf Spring mounting nut and bolt but refrain from making the nut extra tight. Attach the frame elements to their spring shackle mounting bolt and nut before leaving them loose. Elevate the axle support until you achieve 164 - 176 mm separation (6.46 - 6.94 inch) between the axle tube and bumper bracket metal surface. After proper torque at 122 nm (89 ft. Lbs.) on the spring shackle mounting nuts, completely remove the rear axle support. The process includes raising the exhaust system while attaching rear exhaust hangers followed by spare tire reinstallation and eventually returning the Fuel Tank for 2-door utilities before letting the vehicle down.
