Broken off lugnut stud

What kinda job is it to replace 2 broken lugnut studs on the wheel rear on a 02 gt. it almost seems like that abs thing would be in the way. i heard you may have to pull out the axle or something. any input would be great. the douches who put my rims on cross threaded 2 on the same wheel and when i took the rim off later to put my catback on to make it easier they snapped off. sucks :nonono:
 
been there, It's a pain if you can't access power/air tools for pulling the new stud in. you have to release the ebrake cable on the caliper itself then dismount the caliper and use a coathanger to hold it up. rotor comes off easy. just remember a BFH will be the best tool (big effin hammer) to remove the old, On the new i took a sacrificial lugnut and cut the end off so it was basically an open ended nut, i used my impact to pull it in until it crapped out then i went to a breaker with a cheater and that sent it home smooth
