Drifterx,
The studs on our cars are arbor pressed in to the hub. You can bang the stud out with a hammer. Remove the caliper and rotor to expose the hub. Then use some penetrating oil to loosen the stud then tap it out. I recently had to do this when one of the lugs became x threaded on a stud and snapped it. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'>
