It sounds like it coming from the driver side rear. But it only happens when i go over 30mph. And sounds like it pick up speed (sound wise) as my car accelerates. Any Ideas? By the way it sounds just like my tire rubbing the fender but it is not. and again it does not make this sound going under 30mph.

 

bump

 

describe car and what you have done to it? maybe just a buildup of dirt or crap in the brakes?
