I've got this annoying low pulsing 'du du du du du du du" sound coming from my car... can't hear it unless you turn the radio off and actually listen for it, but it bothers me hardcore...

I just had all new brakes put on, as well as my tires balanced, rotated, and the pressure adjusted... so it shouldn't be that...

any other thoughts on what it could be? It sounds just like a warp or something... maybe someone just effed up when they were rotating/balancing my shit? Not sure..

if anyone else has ideas as to what it could be, much apreesh.
