i put my napa joints in the freezer. then put em in...also anit seize that crap out of em.

 

these didnt break easy at all, i had a my floorjack handle cheater bar (4ft) and my 220lb rear end putting everything into it. It sounded like a gun shot when they broke, the first time my wife came outside and thought someone did shoot a gun off. But this is why i buy craftsman, just a quick 10 min trip to sears and i have new tools.

 

my xrf joints had teeth/grooves on them
