Shackle Change Pinion angle
 

I realize there are a few posts with similar questions but i could only find vague answers to help my situation. I just installed a 2 inch lift on my 96 xj with coils up front and shackles in the rear. i get vibes at around 55mph and sometimes when getting on the accel. i meaured the angles and came up with the TC output down 5 degree's and the yoke up 10 degrees. I thought this seemed like alot for only a 2 inch but could this be due to the fact i lifted with shackles? and in your opinions would 6 degree shims be a good idea, to drop the pinion angle 1 degree below the TC to compensate for axle wrap. any input is GREATLY appreciated.
The driveshaft angle is about 11 degrees just incase that helps answer anything.

What angle did you set you shackles at? Its pretty uncommon especially especially in a pre 97 xj, to have vibes with that small amount of lift. Did you set your shackles at appx. 45 degree angles towards the rear?

if the TC output down 5 degree's and the yoke up 10 degrees. shouldnt you ds angle be 5degrees not 11

correction, pre-96 as 1996 was the first year for the new style transfer cases

Yes, you are absolutely correct. Sorry for the brain fart. :)

No redneck i assure you its almost exactly 11 degrees. i have a staock ds
