assembly holds itself in place between the axle and frame. While lowering frame, DO NOT
get under vehicle or place hands between axle and frame. Place frame on jack stands before
continuing work.
Attach frame bracket by placing frame bracket over coil spring seat so that
the cut-out in the frame bracket fits over the raised lip of the seat. Place frame washer over
bolt and attach bracket with 7/16”nut and lock washer. Tighten 7/16” bolt to 35-40 ft-lb.

wrench and tighten the bolt head. To gain additional clearance to tighten the nut, the plastic
inner fender wells can be unbolted.
