Leaf Spring Shackle, Rear

Vehicle elevation and rear axle support at proper height form the first steps before spring shackle replacement begins. The installation process requires the j 36660-a angle meter as assistive tool. Start by removing the shackle nut and bolt attached to the frame and then proceed to take out the shackle nut and bolt from the spring and finally extract the shackle assembly from the vehicle. The installation begins with attaching the shackle assembly to the spring but you must follow all directions from the fastener notice in service precautions. When installing the shackle components to the spring place the rear shackle nut at 85 nm (63 ft. Lbs.) torque before attaching the shackle nut to the frame and applying the same torque setting. The vehicle process ends with the removal of the rear axle support and subsequent lowering of the vehicle.

The process to replace a spring shackle starts by lifting and securing the vehicle followed by supporting the rear axle at its normal height. Begin by unscrewing the shackle nut and bolt that attaches the frame to the vehicle and then remove the same pieces from the shackle assembly on the spring. Once accomplished pull out both pieces from the vehicle. Mount the shackle assembly to the spring after making sure to fasten the shackle nut and bolt onto the spring before torqueing them to 85 nm (63 lb ft). The technician should mount the shackle nut and bolt to the frame before tightening it to 85 nm (63 lb ft). Finally, drop the vehicle while removing the rear axle support. The special tool j 36660-a angle meter should be used throughout this procedure.

The procedure begins with vehicle elevation by suitable lifting tools before builders can support the rear axle at ride height. Suspend the rear axle at ride height before removing the shackle nut and bolt from the frame then the spring. Finally pull the shackle assembly from the vehicle. You must remove the shackle assembly after completing these steps. The installation process starts with attaching the shackle assembly to the spring while following steps for shackle nut and bolt installation to the spring and performing a tightness check on the rear shackle nut reaching 85 n.m (63 lb ft). First install the shackle nut and bolt to the frame and then secure the shackle nut to 85 n.m (63 lb ft). The last operation consists of removing the rear axle support followed by lowering the vehicle down. Installation of the j 36660-a angle meter constitutes the necessary equipment for this operation.

The replacement process for spring shackles starts with proper vehicle lifting and subsequent support before proceeding. First support the rear axle at its ride height before removing both frame shackle parts including entangled nut and bolt then perform the same process with spring components. Disembark the shackle assembly from the vehicle after performing these steps. The first step for installation requires attach the shackle assembly to the spring. Put the shackle nut and bolt on the spring before securing the rear shackle nut to 85 n.m (63 lb. Ft). After you should install the shackle nut and bolt to the frame and tighten the shackle nut to 85 n.m (63 lb ft). Close the procedure by removing the rear axle support before dropping the vehicle. A j 36660-a angle meter makes up the necessary tools for this procedure.

Attach the shackle assembly to the spring, ensuring to follow fastener precautions.
