pinion angle on 2-piece drive line

ok i have a 97 nissan with the 2 piece drive line and the pinion is set at 2degrees pointing down, at ride heigth (2-3") off the ground, and the front driveline is pointing down 5 degrees, and i cant get rid of the driveline vibration, would a spacer on the carier bearing help? or is the pinion setup wrong? heard alot of different awnsers so ?

This has been discussed a few times. Read this article, it is very helpful.

Yep!
