03 4x4 v8 I have been getting a noise that is getting worse. As I speed up it sounds like a prop plane coming from the front. The pitch increases as I speed up as you would expcet from a prop turning faster. If I turn to the right it goes away. Going straight or to the left it is always there. You also feel a resonance in the steering wheel and with your feet. I am thinking maybe wheel bearing, front diff, or maybe power steering. I know it isn't the tires or the axle shafts. Both have been recently replaced. Anyone have any similar experiences? The noise occurs under acceleration and while coasting. the only time it goes away is the time that the wheel is turned to the right.

 

Turned out to be the passenger side wheel bearing. Thanks for all the replies.
