Thanks to all for the good advice. I was able to get it apart. My lesson was this... When it gets too difficult to turn the wrench on the puller, don't get a pipe to extend the handle. Get a bigger hammer or hit it more often to loosen it up. I would only rotate the puller about 15 degrees between beatings. Although initially I was using a hammer, it was a 2 "pounder" with a short handle. I attribute the success to the 3 pounder with a longer handle. I also took the advise to hit the outside of the pitman arm with the hammer, using a brass rod to prevent injury to the pitman arm. I did manage to break my favorite adjustable wrench (12" Diamond Horseshoe), but I was able to finsh the job with a 10" Crescent because it became easier. It oooosed off without a pop. The puller was a cheap $14.00 Chinese puller "borrowed" from Auto Zone. Thanks again. -Scott
