96 GT vibration?? help!!!

I have a 5 speed not an auto.. I was just saying that auto gears would probably be an upgrade.. BTW U-joints made the stang like a new car again and i actually picked up alot of power! driveshaft must have really been out of wack!

You didn't pick up power:( it feels like it though right? That's what it felt like to me when I replaced the DS.
 
If there was an issue with the drive shaft and now it’s fixed you certainly could pick up rwhp. You’re not getting more power out of your motor but you’re getting the power to the ground better.

Yup, no additional power, just putting it to the ground. The weight reduction is nice and the less strain on your driveline is too.
