When highway driving, when I'm 'in the gas' somewhere between 50-65 mph there is a distinct "wawww wawww wawww" noise coming from the front. There is "slight" vibration felt in the floor - but a definite noise. It's not a whine; it's not tires as the ones I have are less than a month old; and the noise is only heard when in the throttle. Coasting - no noise; below 65 - no noise. FYI: All my bearings are in excellent shape.
