Vibrations?

[StangGT96]

Today when i was coming out of the movies my car started to vibrate alot only when i decelarate and it only happens when I'm going about 60 ish. Also when I come to a complete stop the rear differential or something in the back makes some weird noises not grinding or anything of that nature but you here soemthing moving that I never heard before? Any ideas?? Its weird cause it happened all of a sudden. Any suggestion?

well i figured it out. it was the driveshaft, the screws that bolt the drive shaft and rear differential got lose. Anybody know the torque specs? Also can I apply Loc-Tite? thax

How the hell do those bolts get loose? That isn't a good sign to me

A couple of months ago I replaced the transmission and I didn't torque down those screws so I figured thats got to be the reason.
