that sounds like you are going over the rumble strips( but not as loud) on the highway. I checked the front end and everything is fine, It comes and goes, doesn't effect the braking or steering. the strangest thing is it's the same at 50 or 10mph. I had a friend that siad it could be the drive shaft,checked the universals they seem fine, and he said it could be the, what I would call the metal collar with rubber at the rear part of the shaft, like a harmonic balancer. any thoughts or questions, anyone ever heard of this??
