Hi VITAMAN4. Welcome to the forum. Sounds like you have a noisy front wheel bearing. On a few cars, you can tell by the sound getting louder or quieter when turning slightly such as when changing lanes. On most cars with the bolt-on style bearing assembly, it can be impossible to tell, even by where the sound appears to be coming from, unless you listen underneath with a stethoscope while running it in gear and hoisted up.
Bearing noise will remain constant when you CAREFULLY shift into neutral while coasting at highway speeds. Engine / exhaust noise will die down when you do that.
