Hey. I recognize that write up.
btw. I didn't bang on it to get it off. Just wiggled it a little bit and gave it a pull and it came right off. But, I do recommend the correct puller though.
I know you didn't,I only mentioned that important fact as I have replaced a few upper steering column shafts from people using a hammer to remove the wheel.
I hope your article was not copyrighted.
