So I have a strange noise while coasting. It sounds like a human whistling with a bit of wavering in pitch. It seems to be coming from the rear wheels possibly. It is not super loud, can't be heard very well with windows down in traffic.

The noise only happens after the car has been driven for a while(15+ minutes), while decelerating from around 40 to 15 mph. If I hit the accelerator it goes away, sometimes if I touch the brakes only sometimes it goes away, also bumps seem to affect the noise sometimes stopping it momentarily or causing it to come back. It does this with the engine off and transmission in neutral as well. Shifting the transfer case might affect the noise, but doesn't always. I was thinking possibly wheel bearings, but the fact that accelerating makes the noise stop has ruled that out?
:wow:
