OK, I realize this is the short wheelbase page but there is more people on this forum. I have a 1996 ZJ, I installed a Tomkin 41/2" articulating lift on it and it worked well except it looked like a stink bug. Tomkin said to give it time and the rear will settle. After 6 months of towing things it still was high in the rear so I purchased a 2" poly spacer for the front, it looks perfictly level now but about 55mph it startes shaking,now im not talking about a little driveline vibration, I'm talking about a shake that if you don't slow down to approx. 30mph you will end up in the ditch. I have heared it called the 'Death Wobble". So, me being a pretty good mechanic/fabricator, I figured No problem, So here is what I have done so far,I had it aligned and the tires ballanced,I got rid of the track bar and installed a chrome moly one with heim joints on both ends, I made the lower control arms to where they are adjustable now and this morning I moved the pinion angle all over the place to see if I could even get it to get better and had no positive results. my next thought is to convert it over to x-over steering. Am I on the right track? Am I even close? I know the obvious fix is to take out the spacers, but that is a last option, I'm not tired of working on it yet. please help.
