I noticed it coming through Virginia on my way home from NC yesterday. From 20 mph up I have a very loud noise. Almost like a WAHHHHHHHH and its constant. I did notice when I would have to make a semi sharp right hand turn it would go away but once I got straight again or and to go left it would come back. And today on my way home from hanging out with Planeboy it was making a noise just about every way I was turning.

Suggestions?

I would say it's a wheel bearing too.

How old are your tires? I've had two cars make me think it was a wheel bearing, and it ended up being the tires.

jack teh car up, and wiggle each wheel up and down then left and right, see if any play. Usually up and down you can feel if it's a wheel bearing. I had the same noise, but for me it's my tires.

I have the same noise on my 2004 GTP. It sounds like an SUV going down the road at low speeds. When I speed up the noise lowers but still is clearly there. My tires are cropped and will be replaced in a couple of weeks with Bridgestone Potenza's. Easy way to notice on my tires for cropping was look at the tire and see if the tread goes up and down like mountains. Or run your hand from one side to another long way and see if its smooth or rigid. My step dad will also check the wheel bearings as well. I just purchased the car in May and it has almost 100k. =)
