I have 99 wrangler and have been running a Rock Krawler long arm kit for 6 years now. I installed an 8.8 in the rear and a HP Dana 30 in the front. I squared the axles and centered everything up. Upon acceleration, it goes straight and wells. The problem is, when I let off the gas, it feels as though the rear axle shifts rearward on the drivers side. The joints seem fine and the upper links are new. I can't figure this out. Amy help is appreciated!
