I haven't had a problem with broken 1/2" breaker bars, and I've replaced both axels on my accord. I use an 18" craftsman breaker bar (even if it does break they'll replace it free), put the car up on jackstands (both sides), have a friend stand on the brakes, and then I jump on the breaker bar. Both times the nut came right off after a bounce or two. I'm 250lbs tho, - thats 400+ ft-lbs!
