Wheel bearing dust cup.... You need new wheel bearings and wheel grease. I am sure someone on here know a P/N for the dust cup...

And I advise you don't drive the car another foot at a decent speed... You will eventually end up with three wheels going in one direction and the bad one going off away from the side of the car as though it had no lug nuts on it, taking the brake rotor with it and destroying the steering arm most likely.... and a good portion of the body will be wrecked in the same instant...
