got squeaks? i do.

well, after much searching..I have found nothing on my issue at hand.

I have a squeak that i cant seem to figure out the source.
it happens when i am sitting in traffic, and rolling along at a constant speed, clutch in or out. and its not constant, its like a squeak. break. squeak, but its timed in sequence. as soon as i get on the brakes, or touch the gas, it goes away.

I am dumbfounded.
could it be breaks? wheel bearing? ive got no idea, so any help would be greatly appreciated.

Thanks,

.:Nick
