vibration at 50MPH
I have a 99 mustang with aje k member and cross member with upr solid rear bushings. I had the tires balanced yesterday and are good to go. My problem is at 50MPM my car starts to vibrate you feel it in the seat and the faster you go the worse it gets. If you let off the vibrations come and go until you get below 50ish MPH any idea's?? I have the pinion angle set to -1 and the drive shaft is new.

Can you put the rear axle on jack stands and spin up? Then you could determine if driveshaft or rear tires (you could also remove rear tires) to isolate.
Do load the axle so you can approximate operating driveshaft angles. You might want to post output shaft (vs. ground), driveshaft angle (vs. ground) and input pinion angles, too. -1 doesn't help much without the others.
