If you broke a stud off the front, you will have to remove the whole spindle and hub as one piece, then you have to take it to a shop to have them press the hub out of the spindle, then they will tap the stud out and pull the new one in...If its in the rear, then you can easily just hammer it out, put the new one in and tighten it into place with a stack of washers and your lugnut...
You may be able to get to the front stud while everything is on the car, but you will see that only 1 or 2 can be accessed and the rest will be blocked...
