I had the shop look over the lift. (not sure if they re-tightend everything) and told me everyting looks fine. no split bushing or anything. I also have the slight vibration at idle. I tried the water cup trick and sure enough its shaking. I guess i am going to be one of those few who wait untill they come out with something to fix it to get it done. Only because there is way more things that could be the problem on my truck.
