How do I find my driveshafts u-joint angles???

[morcav]

I have been getting some really bad vibes coming from my shaft, and need to figure out how to correct them asap. What I've gathered so far is that I need to shim my rear diff, but how do I find out what degree shims to use? Everything (driveshaft, axles) is stock exept a 4" lift with blocks in the rear and 35's. Going to a 4 wheel drive shop or a driveline shop is out of the question being that I'm stationed in Germany right now. Any help is greatly appreciated.

You can just get some 3 degree shims and stick them in and you should be ok. Some need them with a 4" lift, some don't.

Read this: driveline 101
Pretty much Everything you need to know is covered there.
You can get an angle finder from most any hardware store (even in Germany). I bought mine from Ace for about 10 bucks.
