I got the same thing from a 2" OME lift! Nothing seemed to work so I finally swiched to a double-cardan joint in the front of the driveshaft and wedged the rear 6 degrees up to get almost 0 degrees of angle on the rear u-joint. It's still a little bit low in the rear pinion but the vibration is 90% gone.

4Crawler, what would a set of 7 degree wedges go for, shipped to 98226? I'm still running the aluminum Pro-Comp wedges I bought to get the angle right. I think I paid $18 a pair for a set of 2, 4 and 6 degree shims.

Thanks.
