I was on my way to work today, and as I was pulling into a parking spot (had the wheel turned left quite a bit) I heard a noise that sounded a lot like a flat tire. (whump whump whump) or the noise you hear when you get a bad throw on a bowling ball (where the finger hole makes the whump sound as it goes down the alley). Anyways, as I was leaving, it still was making the sound, I turned the wheel right, and it stopped the sound. Haven't heard it since. So what could this be. I do have warped rotors, but I am unsure if that could have caused that sound.
