I recently installed an ORD 4" shackle flip in my '89 Jimmy. I am using the stock springs, and I replaced all the bushings with greasable polyurethane bushings. I have not driven it much, but it definately has a fair amount of "sway" compared to stock, is this a normal side effect of the shackle flip? It also seems like the steering is really vague, and it has pretty bad bump steer, I installed a set of heavy duty shackles up front which are longer than stock so im thinking this changed my caster (?) somewhat. Could this be what is casing my bump steer and if so how do I correct it? I already had it aligned and had both driver side ball joints and a new drag link installed.
