The vehicle just started doing this...happens on straight and level road as well as bumpy road.. bumps just make it worse. Still does it when you push in the clutch or put it in neutral at 60 mph.... making me think it is not the drivetrain. I cannot feel the vibration up the floor gear shift so I think its the front end somewhere... Kingpins have been replaced about a year ago..does not wear the tires unusually.
