I took it completely apart and cleaned them both but found nothing. The motor doesn't wobble without the belt and I can't "see" any defect when they are apart, just when they are working together. It's also at the same point in rotation. So I was with you initially that something got lodged in between the two but I haven't found crap! lol.
