get the nut buster, and be careful, dont damage my front hydro's in the process, haha
dremel it off and get a new nut or dremel the whole stud off and get a new one
Heres what you do I had the same problem so I have a neighbor that works on cars for a living and he just took a socket pounded it over the nut(it ruined the socket) and then just turned it off like you would do as if it wasn't stripped.
