Grigg, I think you hit it spot on. The rear pinion angle was at 4 1/2 degrees up, the rear drive shaft at 5 degrees and the front shaft at 2 1/2 degrees. A fellow that I was talking to that does a lot of hot rod work pick up on that. He asked due to the fact that the stock drivetrain was pulled. He said the vibration sounded like a pinion angle issue. Soooo...I shimmed the rear axle, to a 1/2 degree up. Took it on a test drive and the low speed vibration was gone, felt slight vibration at certain speed. However, still has a vibration at higher speeds(40mph and up). My friend seems to think that if I dropped the carrier bearing to add another 1 to 2 degrees to the front drive shaft that it may take care of the vibration. What do you guys think? Thanks for all the insight, guys.
