I just completed my 1994 chevy 350 v8 to 1993 Jeep Wrangler Conversion. Everything works great, except (there is always one of those) when I am slowing down I get this horrible vibration and rattling noise. I have jacked it up and ran the engine and then slowed it down and it does the same. My drive shaft is very short, the local jeep shop which have been known to make mistakes think I need a SYE kit to fix the problem. I was just wondering if anyone had another suggestion or if I should just do that. I would hate to spend $ 350 to get this kit and it not be the problem. I have a 350v8 700r4 and a np241 transfer case. Also I have access to parts so if you can think of a shorter t-case that may work let me know. Thanks guys and the few gals out there!!!
