Expo 8.8 W/ 4.56 Gears Installed Finally!!!!

So about a week or so ago i finally got an expo 8.8 and put it in. well thursday we hired a new tech at work, and he rebuilds trannys and axles. so i talked him into putting in my 4.56s. Truck works awesome now no struggle trying the push the 33's with 3.73s. my only problem on the way home, was i can feel the driveshaft wobble still. I replaced u-joints, and checked play on everything so now i know its my pinion angle. im just a little confused on how to find out my current angle, so i can get some degree shims on it. if someone can explain this in a retard form, so i can understand, that would be awesome thanks so much!

You didn't set your angle when you welded on the new spring perches??
did the drive shaft wobble before the expo swap?

you didn't measure it when you had it under the truck? bad juju.
Get an angle finder and measure the angle, or just look at it and see how bad its off...if at all. i am not sure what else could be wrong.
