Hand-install the new leaf spring bushing into the left leaf spring eye first. Following this, set the Remover/Installer, Special Tool 8459, over the lifting eye and bush of the leaf spring and fasten the Set Screw to connect the Installer Plate (8459-3) with the shaft. Secure the bushing into the spring eye so that it's not completely flush with the spring and there is still some gap between the bushing flange and the spring eye. After getting rid of the Remover/Installer, bend the tabs on the bushing outwards so they press against the part of the spring. Before assembling the bushing, place the spring mounting bracket over the spring eye and thread the pivot bolt through the center, from the outside. Screw the nut onto the pivot bolt and don't tighten it completely right now. Raise the forward mounting bracket using a jack and fit it against the body, using a drift punch to direct the mounting bracket through the hole in the center of both bracket holes and the pilot hole in the body. After the four mounting bolt holes on the bracket line up with their threads in the body, install and tighten the bolts to 61 Nm (45 ft. lbs.) torque. Place the jack so the lower eye of the shock aligns with the threads in the axle housing and install the lower mounting bolt partially. Once the vehicle is low enough, take out the hoist arms and the pieces of wood set up underneath it. After that, secure the spring front pivot bolt with 156 Nm (115 ft. lbs.) of torque and the lower shock absorber mounting bolt with 88 Nm (65 ft. lbs.) torque.
