wheel stud replacement
 

hey guys, i've got a 1995 camry 4cl. I am trying to replace a few broken front wheel studs. I've got the tire and caliper off already. How doyou take the front rotors off on these. Do I have to take the wheel bearing locking nut off first? It appears that I do but I wasn't sure if the rotor was just rusted on really good. If that is the case do I need a special tool to remove the bearing locking nut, I tried removing it with a 3 foot breaker bar and it didn't budge. any help on this process would be appriciated.

Thanks
Frank
