06 GT, auto, no mods (yet).

Looking for all possibilities: Hum/Moan type noise from rear end, consant pitch and volume from about 40 mph to 65. At 65 mph, it increases in volume (louder) by about 50% - again same noise, same pitch, just louder. Fades off at about 68-70 mph. I don't hear it at all above 75 mph. No change on throttle position (accel, decel, cruise). No change in gear position (including neutral).

Key point: at 65 mph, I noticed if I swerve in one direction, it goes away (or greatly reduces), if I swerve in the other direction, it gets louder. that made me think it's a tire issue, but a recent tire rotation did not cahnge the noise.

Other than tires, could it be:

-a differentail bearing? If the bearing is shimmed too tight, would it make this type of noise?
- clutch pack? I don't have any noise on low speed turning.
- other?

Rather than go into detail about the service history on my car, I'd like to just get some ideas based on the info provided. TIA.[/align]

If you haven't done any mods to the rear, whatever it is, should be covered under warrenty.

I have a sort of high pitch noise in 5th at a contant speed, told it is normal? Any one else have that?

So, on the way home fromwork tonight, I tried serving again. Swerve right - noise diminishes. Swerve left - louder. Then I just VERY slightly swerved right and left, I'm talking as little as possible - same result. So now I'm thinking it's gotta be a FRONT tire or bearing, 'cause the load on the rear wheels isn't changing that much to cause such a difference in sound. So now my question is - does anyone have a diagram or picture of the front suspension? This may be a dumb question, but where exactly is the front wheel bearing? I searched fordparts.com and all it shows is aHUB AND BEARING. Is that it?

That's it.
