The pinion angle is the angle that the pumpkin is sitting relative to the driveshaft. The angle might be too excessive causing a vibration.

Try lubing the u-joints first..

lastly how fast are you going in 4x4?

Id say your driveline is has severly wasted u-joint(s) that are causing the vibes.  Got any pics from the side to see what type of angle you have?
