i would measure the rear end and the drive shaft with a angle finder.... add them together to get -2 degrees

iTrader: (6)

Ill try it and see what happens.

I haven't had much time to mess with it but its narrowed down to the carrier or driveshaft balance/angles

Chassis mount ta? I'm getting a lot of vibration from my MWC 9" and I think it's b/c of the t/a being mounted to the chassis.

Its a full length umi tq arm with a umi relocation kit but it uses a poly mount

Did it vibrate before the umi ta relocation kit?

94dragbird

iTrader: (6)

No. I did the relocation kit when I still ran the 10 bolt and didn't have a problem

mine is the adjustable umi arm with the drive shaft loop that mounts to the body..... i was told the axels may be untrue

94dragbird

iTrader: (6)

Both mine are true

Punisher_ws7

iTrader: (6)

94dragbird

You said you tried 2 different driveshafts, what yoke(s) did they use? I had a yoke from strange that just didnt fit in the tailhousing right. It wobbled a little, like it was loose in the bushing or the splines werent cut right. I bought a new yoke from Mark Williams and it fixed the problem. Also verify that the driveshaft is the correct length, that could cause the same problem.
