I'm not there, so I'm only saying what I've seen on other cars, and is likely, not necessarily your problem, as Bogie sa8d.
That said, an AWD Cx9 is going to have some kind of limited slip dif in there, and if you are turning the wheel slowly by hand, and that slip is grinding you've got a real problem.
Maybe jack it up again, put it on a jackstand and lie with your head under the CV shaft while someone else turns the wheel to make the grinding noise. That will help localize it to outboard (bearing, brake, wheel/hub assembly) or inboard (dif.).
Again, I'm not there, but usually when I hear grinding from a wheel on a car that otherwise doesn't show drive train issues, it's wheel bearing and/or brakes. Could be bent dust shield, could be wheel bearing allowing rotor to be out of true with weird wear, I've even seen a bearing bad enough that it let the wheel rub the shock. Hard to say without looking at it.
