Well i just put in the new rear-end in my car, and i went over everything 5 times to make sure it was right, and tight. When i launched the car out of 1st it makes this grinding noise that i have no idea what it is.. I think it might be the tranny mount, or might even be something rubbing, could be the yoke.. might have messed that up?? Dont really know. Any info or opinions are welcome.

THANKS

 

oops.......its on a 1995 Firebird A4 3.4L
