zooming noise from wheel

Good afternoon.
This weekend I noticed that my left front wheel is making a zooming noise. It does not matter if I go fast or slow or if the car is in nuetral going dowhill. It constantly makes a zooming sound....kinda like this. zoom zoom zoom zoom zoom zoom zoom zoom. As the wheel turns this sound continues.
I think its my transaxle...what do you guys think it might be?

You might ran over Mazda and it stuck some where in fender well area.:D


Ok, enough of be funny.
That noise might be worn hub bearing.
