Well I found out what all the scraping was during the spin cycle...the sump guard metal seems to be warping and the screws from the paddles are scraping it...and actually chewed through a piece of it...in consulting the service manual, there is an additional piece of metal missing that looks like it would hold the piece down that is being scraped by the paddles...and to fix it the tub has to come out...(not a fun process according to the service manual)
