broken wheel stud

Someone please help, I broke one of my wheel studs while changing a tire. I went and got a new one and took the brake disc off but where do I go from here. How do I change it? Thanks in advance.

Front or rear?

another member explains the process, but if your lazy and or not confident in doing this yourself just take it down to a local shop and they will do it for for 25-45 bones. Not really a hard job just takes a bit of muscle with the slide hammer to get the hub off.
