1. The absolute first thing to do before the suspension was to install some T and J chassis stiffeners and under-rail skids to help prevent the body from bending. I've been in an XJ with chassis stiffeners before, and the difference in handling (even on the street) was definitely noticeable. The skids help further stiffen the body up, and offer protection from rocks. Once you compromise the lower "frame-like" rails, or unirails, the Cherokee's body will bend much more easily.
