Smoking hub, HELP!

[Sweet-85']

Ok, so I'm driving home today, and all of a sudden my truck starts pulling hard to the right, and when I hit the brakes it'll take off to the left, I get home and the hub is smoking like crazy. It's the right hub, I pulled the wheel, and took the hub cover off, and the grease was pitch black, but the mechanical components looked fine. Help, what did I break???
