I couldn't get them out on my 84 truck even with the socket. So I do have a mig welder. I welded a short piece of scrap 2" tube to one and the heat of welding loosened it up enough to spin out with a pipe wrench took the one I had out flipped it over and welded it to the outer side and it came out easy to. Threads were fine and quite clean. Have some water handy as the grease in the old ball joint tends to catch on fire!
