Hi!

My car, '03 rsx auto trans, just passed 70k miles. It's been meticulously maintained. Starting yesterday, theres been this weird grind/vibration coming from the front left corner of my car. It only happens within the first 1.5 secs of normal acceleration. If I accel slower than normal, it doesn't happen. It's not so mucha grind it's more of a anti-lock modulation noise/feeling, sorta. A rapid "brbrbrbr."

It doesnt'y happen when I'm revving the engine in neutral. It also doesn't happen if I'm going acceling in reverse at a similar rate. What could this be? Great thanks to anyone who can help.
