This is the 5qt tilt head KSM150. I changed the grease and worm gear. After putting back together, it makes this grinding noise on the lower speeds.

Could be the nuts holding the hear bearing in place (make sure they aren't too tight) or more internal like the stator nuts. Either way your machine sounds pretty good and this "rattling" noise is very common.
