WildBlue goes RideTech

No sorry I didn't fully explain. I've always had vibration problems. I know it's driveshaft or pinion related. The car is smooth as glass otherwise. It doesn't really start vibrating until about 50 MPH. I know part of it is due to the 4:11 gear and high rotational speed of the shaft. I honestly wouldn't be surprised if the shaft is out of balance because as far as I know it's the original shaft from the car.

Oh, ok. Then you can assume it was the shaft in the first place. 4.11 gears?!!? Damn Gina!
