Yea I know it's old, but I figured I'd post in this one rather than making a new thread just for that problem :)

I redid my front brakes, got new pads and a rotor, one of them had a giant fissure carved in it from my pad being so bad that it was grinding into my rotor O.o

Got my wheels balanced as well. But that noise is there, I haven't gotten around to checking te pulley's, I get back monday from vacation so I'm going to get a video up so you guys can hear it, make sure it is or is not the pulley's before I start messing with it and its actually not them.

I'm not saying you don't know what your talking about, by no means think that, I just figure actually hearing the noise would help you guys come up with a more accurate diagnosis :D
