This sometimes requires the use of a press. This tool may be available for rent or sale at a parts store or tool rental shop, but for the cost of the rental, most any tire shop can do it for you. If you really want to do it yourself, here's two methods:
Method 1: (With Press Tool)To do it yourself with a press, remove the wheel and brake drum (you may have to tap the drum carefully with a hammer or rubber mallet to free it). The broken stud may need to be ground flat for the press to work on it. Attach the press as per it's instructions and press out the old stud. Feed the new stud into position and attach the press again as per instructions (probably in a new configuration) and press in the stud. Take the opportunity to inspect the remaining studs for flaws/damage and replace as necessary. Reinstall the brake drum and wheel. Retorque any loosened wheel nuts after 100-150 Kms / 60-100 miles driving.
Method 2: (Without Press Tool)I just did this myself not long ago, it's a very simple operation that took me under 30 minutes. You will need a hammer, a punch maybe (if the stud is broken flush with the hub flange), an 18mm wrench or socket, 3 or 4 flat washers and a generic wheel nut (costs about $1), a little grease, brake cleaner, and your tire iron (or better yet, an 18" breakerbar with 3/4" socket).Assuming that the vehicle is jacked up and supported safely and the wheel is off:
