i had this same problem on one side. changed out the bearing boom fixed. then the other side started. something was also loosening my castle nut. now ive replaced all the same as you (cv, ball joint, hub, cone washer*ETC.) i also had my brake bracket get grinded down. today i put it back together and ill let you know where i get. my bearing looks brand new. but i think im replacing the bearing next if it doesnt go away.
Ill keep you posted.
