To those who where asking last time this was posted, that metal to metal noise was coming out of the differential. It was a dry spline. Dealership said it should be lubed everytime the tire is changed, funny they changed the tire last time. Oh well, lubed up, no noise, no damage done, giddy-up!
Check the pinion cup and drive shaft end. If the drive splines weren't serviced, I'll bet those weren't either.
