there is still a clanking noise or sounds like bearings grinding themselver to bits. I just spent the last hour plus some removing and replacing the serpentine belt to see if I could make any of the pulleys make noise but nothing, The only thing i noticed was a barely audible chirp from the idler pully which I don't think was it at all and that the water pump shaft moved in and out a little bit. The belt however keeps it from walking. Any thoughts?
