unbolt it and turn it 90 degrees, try it out. if its not better, turn it another 90 degrees, until you get it just right.

Before I read that, my first thought was that because the alum DS's are about 1/2" larger in diameter than the stocker, your new alum DS might be rubbing a muffler, etc while driving.
What you said raises some red flags for me though. Get it figured out ASAP.
Good luck.

ok, i just pulled out the aluminum shaft, the u-joint that goes into the tranny is a bit hard to move around. i compared it to my old and it much easier to move around. my old u-joint is greasable and the one on the aluminum is not greaseable. i dont know if the join is shot or if it needs to be balanced
