Why do you say that the drum is loose? Are you able to wobble it by hand? If so, that is evidence of a bad roller that the drum sits on.
If the drum doesn't turn as fast as it did, that is probably a loose belt, which would indicate that the belt tensioner is not working or belt has jumped the tensioner.
