Hi, got a sweet deal on a trailmaster 4 inch lift. Now have very bad rear drivetrain vibration. Have tried shims but not much help. Any suggestions? I heard cv driveshafts might help?
anyone else had this problem?
thanks in advance!

How did you figure out which shims to put in?
It is possible that the wrong shimms were used of installed incorrectly turning the pinion the wrong way and making the angle worse.
You could also lower the Tcase a lot cheaper than a cv srive shaft

fwiw my 4" lift has a 1 1/2" tcase drop and a 6 deg shim to cure my bad vibes

Hey Kelly. I guess this post answers the questions in my email ;D Anyways, I didn't think about what gmule said. The shims are installed correctly right? The thick part of them at the rear of the axle?

I have 15" of lift in my truck, and I have no driveshaft vibration. I do however have too much angle on the driveshaft...
