Lug studs are pressed in from the back side and on most cars, if you rotate the axle to a specific point there is enough room to knock it out. then once you have the proper replacement, it can be "pulled" back in using a lug nut and washers as spacers. I have had lug nuts get ruined by this procedure so buy extras.
You will have to remove the wheel hubs and knock the broken studs out through the back of the hub. New studs are then knocked in through the back again. For future reference, the torque on wheel nuts is usually in the region of about 70 ft/lbs ie. if you have a lever about 2 foot long, apply a force of 35 lbs on it. This torque is quite sufficient and a woman would be able to loosen the nuts if stranded and had to change a wheel.
On second thoughts, while you have the hubs off you may as well replace all the studs on that wheel, the chances are very high that they have all been stressed and weakened and you do not want to have to go through the process all over again.

Knuckle needs to be removed and the center hub 'pressed out' using a hydraulic press (accepted procedure). You can avoid this by using an air hammer and disk cutting tool to remove the old stud, then trim the 'stop flange' on the new stud (1/4 moon cut) in order to install it.... however, you gotta know what you're doing so you don't compromise the integrity of the new stud.

I'll try to help you. If you are having trouble with 3 out of 5 studs on one wheel you may want to go to an autoparts store or Salvage yard to look at the whole hub. Usually a press is used to remove the bolts so you would be taking off the hub anyway. When you pay for 3 bolts and labor you may be better off in a Salvage yard or parts place for a different hub. The rear hub on front wheel drive cars is like a trailer axle. Much simpler to remove mounting bolts and press in new bolt. But if rear has differential(rear wheel drive) it has an axle shaft. Would be easier to grind and drill out broken stud on car. You can draw new bolt into place by placing bolt through a socket and use the wheel nut to draw the bolt into the hub.

1. get new studs and nuts
2.remove wheel
3. remove caliper at bracket to spindle connection(2 18mm bolts?)you may need to remove caliper from bracket,but not always nessacery. Or remove drum,then to #5
4.remove rotor,will need a hammer, tap inbetween studs dont wreck good studs and see if new studs can be installed without removing parking brake shoes. If there is no clearance to get new stud in you will need to remove shoes.
5.Pound out old studs place new stud in hole use a washer on outside then put a nut on and tighten to install stud, A air gun or some type of impact tool will be very helpful. Check to see that stud has enough threds to pull stud all the way thru ,add more washers if nessecary dont let the nut run out of threds it will **** to get back off and wreck new stud.
6. if you dont have air gun or feel comfertable removing brakes bring it to a reputable garage, shouldnt cost more than $70+ parts to get all new studs put in on one wheel.

grab a large punch and hammer and knock out the old broken one. Push the new one in and re tighten. This will pull it into place and because it has splines it should not spin while doing so.

Remove: wheel, brake caliper & rotor. Drive out the remaining stub with a hammer and punch. Insert a new stud and pull it into place by tightening the lug nut. Before running out of threads, remove the nut, insert a stack of washers or a large nut which slips over the threads without contacting them, tighten the lug nut to seat the stud.
