Before the 3:73's were installed there was a slight but tolerable vibration in the 65-70 mph......rear view mirror was still usable. That's not the case now. 
I'm guessing driveline balance may be off as Blake mentioned, but that yoke depth could be a contributor. When the car was on stands with the rear unsupported the yoke pulls out about 1/8" from the ride height position and there is some slop, at ride height the slop is reduced to what I "think" would insignificant........but thinking has got me in trouble more than once. |
If its noticeable on decel, roll the pinion down further. I just had to reset a ridetech 4 link that had a vibration on decel. I would roll it at least 1-1.5* down if you have not done that yet.
