Alternative rear lug stud replacement?
Ok so this thread is not about how to replace lug studs the "normal way". I am posting because I have a 93 rx7 touring that I just put rear wheel bearings into and about a month later my lug stud snapped when I was torquing them down properly with torque wrench. I am wondering if anyone has found a way to effectively replace them without ruining/taking apart my wheel bearing I just replaced? 
I have searched but have come up with nothing other then the "take everything apart and replace wheel bearing way"
Also this is on a completely stock rx7 not one thing aftermarket on it.

If it were me I'd replace all five studs while you're at it.

AFAIK, no. Part of the bearing will probably stay in the hub when you press it out and have to be replaced....again. If you could get the hub hot enough somehow, you might get lucky. But by that time you'll probably destroy it with heat anyway. Sorry.

While not un-heard of, I don't think it's particularly common. Now...if someone in the past used a big impact and drilled them to 450 ft/lbs......all bets are off. 
FWIW, ~ 80 ft/lbs. has always been plenty for me on the stock wheels.
Did you get the OEM studs? I've had issues with aftermarket ones on another car I owned.

Could you post a picture of the broken stud and the area around it you are trying to work with? I'm new to the forum and new to the rotary world. I am however, a Master Mechanic who owns his own shop. If I can see what's going on, I may be able to help you with your problem. Please PM me when you have pictures up.

Unfortunately, you have to remove the wheel hub to replace the broken stud. There just isnt enough space to push the stud out and replace it with the hub in place. If you need a wheel bearing, I carry nice Japanese Koyo bearings for $50 on my website www.j-auto.net. Normally a broken rear stud is a few dollar job on any other car but the FD likes to kick us while we're down sometimes

I was just throwing it out there. Sometimes there are "cheats" like grind a little off here or bend this thingie over here, I'm sure your're well aware of this. I wasn't aware of your background but I'm sure you've got it under control.
