Drivetrain vibration on acceleration

Since added the turbo to the car I've been having a drivetrain vibration on acceleration. It seem to be worst in 1 & 2 gear. I've already changed the transmission mount and u joints. I noticed the drive shaft sometimes hits the car under the parking break. I still have the stock control arms in the car. Could a damage/worn out control arm bushing cause that problem? I have steeda springs with tokico shocks if that matters. I really think it is coming from the rear end of the car.

Thanks

What transmission do you have? Also, have you checked the driveshaft to confirm its not bent?

I had the same problem & initially assumed that it was the used aluminum d/shaft that I installed. Purchased NEW aluminum d/shaft ... same problem. Installed upper/lower Steeda rear control arms ... no more vibration & the bottoming issue is gone. I think that MM says that you only have to replace the lower arms, but I took the shotgun approach to fixing the problem cuz I just got tired of chewing up the d/shaft.

T45, How could you check to see if the driveshaft is bent?

yeah I went ahead and ordered aftermarket upper and lower controls arms. Hopeful that will fix the problem. How do you like the aluminum d/s?

Any driveline shop can check it for you. I liked my aluminum driveshaft, never had any issues. Are you getting the vibration through the seat of your pants or more-so through the shifter? Your asking alot from that T45 with the power you are making..

My T45 has been great, but I know it is on borrowed time. The tranny shifts fine. It really feels like the vibration is coming from the rear but is also shakes the parking brake pretty good. If I punch it from a 45+ roll it is fine. Like I said the D/S sometime rubs the bottom of the parking brake.

Janstang, thanks for the help your setup looks awesome. What kind of power did it make?

Thanks..Never dynoed it, I street tune everything. I can say it runs in the 9's and it destroyed the built C4 tranny.
