2008 Other Ford Models Wheel stud replacement

Two months ago I purchased a 2008 Ford Explorer Sport Trac. Not willing to leave well enough alone, I also purchased through Craigslist after market 20" wheels and a set of "new" tires. Well, the tires turned out to be out of round and one of the rims was slightly bent ( this was not apparent until I had the tires balance). Because of all the tire/rim on and off procedures, done at different tire stores, one of the front wheel studs broke off, as somone using a pneumatic tool probably cross threaded the nut to the stud. Of course, everyone is blaming everyone else, but I'm the one with the broken wheel stud. Would you please explain to me the best way to replace the broken stud. I know I will have to remove the caliper and rotor, but beyond this, I do not know what is the best way to take out and replace the stud on this vehicle. Any pictures or diagrams would be appreciated as I cannot get any shop manuals because the vehicle is too new.
