Sometimes they're easy, sometimes they're hard. The first one I did after a 5# sledge, 2 bottles of liquid wrench, 1 bottle of PB blaster (or Zep, can't remember), airchisels, hammer, etc. I finally called a relative with a torch. He torched 80% of it off and we hit the rest (even a part that after being cut was not held by the stud) and nothing happened so we cut it off too. Had to replace one stud as we had to cut the cone washer off it and it messed up part of the thread (cone washer was welded/rusted to the stud and would not budge. Others (even ones that looked more rusted), I have soaked, removed the nuts, whacked the arm a few dozen times, and then removed it easily. I guess it's luck of the draw, and Murphy's Law.........I was in a rush to do the one that had to be cut off, and didn't need to rush with the one that came off quickly.....go figure. /forums/images/icons/crazy.gif
