For those familiar with Mother Mopar and unusual decisions they made back in the day you probably know about swedging brake drums and left hand thread lugnuts.
Basically the wheel hub and rotor are assembled and the lugs are squeezed together as one unit. So to do a brake job you need a special drill to machine off the flared end of the lug on order to replace the drum. You can try a BFH and bash them apart but if you are keeping the drums this can distort them. But if you get a wild idea about replacing the lugs with replacements (like eliminating the goofy left hand threaded ones) then you either press them out or drill them out.
Resorted to drilling them out after trying to press out with a bench vise.....
