If you have a receiver hitch assy. It MUST come off first before you can take out the bolts from the leaf springs to install your leveling kit. When I went back in with the leaf spring bolts, I went the opposite direction, which is what should have happened at THE FACTORY in 1993. Bolts should go in from the outside IN, not the other way. I fought, and fought and FOUGHT to the damn death until I figure out what in the HOLY Hell was the problem.
