Ben,

I have been working on a nearly stripped out CV bolt on the wheel side for the last week.  I finally got it out last night.  If you are able to get a grab on the bolt with an oversized allan bit try using a hand impact driver to break it lose.  I searched the archives and found several posts where people had success with this approach.  Another method I almost tried was using a dremmel tool to grind down the sides of the bolt head.  Then a vice grip could be used to turn the bolt out.  Only problem is the lack of acces to those bolts.  I used a razor blade to cut off the rubber CV boot which gives you a lot more room to work in there.  I found another post in the archives where somebody used a dremell tool to cut off the bolt head.  Once the joint was removed they used a vice grip to remove the stud.  If worse comes to worse you can always drive out the hub thing that the CV joint bolts onto.  I suppose this would require removing the drum, axle nut, wheel bearings, etc.
I called Sears and they told me they do not carry the 12-point "tri-star" bit.  I have one on order from Bus Depot (about $7) that should be coming in any day.
Good luck and keep us posted.
Jake
