For me, anyway, sometimes the double nut slips. With this tool, you heat up around the stud (within reason) and grab with tool and turn.Soon as you apply pressure, there is an audible click and out she comes.

It can be difficult to get the correct angle on the removal / re-threading tools with it still installed. Ooops! Did I say "when"? I meant to say "If". https://i.imgur.com/tmuGzov.jpg

Sounds familiar. I had a '69 Chrysler 300 2-door, broke a stud and spent a frustrating 5-6 hours trying to get it out. Then I realized it would've been faster to just remove the head - had the head off in 45 minutes and the machine shop fixed it (and a messed up spark-plug thread) for $20. https://i.imgur.com/tmuGzov.jpg

I still would use a little heat if it didn't want to come out cold. The cam lock tools in the rear are not nearly as effective as the collet stud tool.

Though I try to use the hot wrench and hammers as little as possible there is one app that I use the torch almost every time & that is on every ex stud. I'm wondering why the other place advised against it. If it wont come out w double nutting it w a reasonable amt of torque then I fire it up live every 24 hour block of time like it's your last day on earth

Then quench the stud with a spray bottle. Try to remove it gently. If it's still stuck repeat. Still stuck? Reheat and melt a candle into the threads, cool and try again. I would also recommend the Craftsman stripped nut remover set. It's about $25 and grabs about anything. I've had this method work nearly every time,and I've done quite a few. Good Luck Doug
