This is what I've done with great success, there's a bit of a raised spot on the side knuckle hole that hitting works wonders onDrilling hammer or a big ball peen on the knuckle itself, where the stud goes through. The shock will jar the tapered stud loose, it works 9/10 times. You can improve your chances by adding some PB Blaster to the mix and maybe some heat with a torch, but usually the hammer technique does it for me.
Heat, people. Heat.I beat the piss out of mine, but obviously that requires commitment that the stock parts will be destroyed and there is no turning back.
