ok, i know countless threads have been done about this bugger coming off. i once read that there is a "sweet spot" to pound on to break it free from them cone washers. I have been beating it with a 3lb hammer in pretty much all spots, and i even hit one of the studs and damn near ruined the threads. I sprayed on some PB blaster and whacked it over and over. i dont have a torch so i ended up putting it back together. what am i doing wrong?
