I would agree with the pinion angle. You dont have any vibration or anything do you? Also there isnt any play in the pinion itself is there. Just trying to narrow something down here. And are you sure the new ujoint was installed correct IE. Im just saying because, a friend of mine installed one on his truck and really had a hard time getting the old one out and he tweaked one of the ears on the Drive shaft. Ended up slowly eating one side of the U joint cup.

Im estimating the highest driveshaft speed I need to be around 7000rpm. The shaft being so long presents a problem....
Anyone else with a setup like mine know their driveshaft length off hand? I spoke to dennys on the phone and he suggested a 5" shaft.

I had a new 3 1/2" steel one made (they spec'ed with my power goals in mind) when I did my 4l80e swap, 2 different shops could not make it balance right, just too long for a 3 1/2 steel and over critical speed of it. The shop that built it told me he could just shorten my stock 5in aluminum shaft... I was like I would have just done that in the first place and saved the $300 if I'd know that!
So for size, min 4" steel, or 5" aluminum.
