So this is a continue of the previous post "Bad Vibrations" I had the drive shaft rebalanced and it was out of faze and they corrected everything thing and said that it was worse then they anticipated. Anyways... now that the corrected driveshaft is in place it seems that the vibration has gotten slightly worse and now there is a loud low or bass rumble or hum. What else am i missing what could all of this be??? ANY thoughts??
