I put a shackle flip on the back, and now, only under power, I get a nasty vibration. I am thinking that it is my rear driveshaft... I looked at it, and the pinion angle is waaaaay off. In fact, the pinion is almost pointing right at the transfer case. I added 5* shims when I did the lift, but they weren't enough. I assume that the easiest fix here would be to get a CV joint driveshaft. This brings about my questions: 1) is there a cheaper way to fix the angles? My wallet was completely drained from the lift 2) is there a way to put a CV driveshaft on a 208 transfer case, without breaking the bank even more? Thanks for the help.
