O.k., well, it's off. lol
I put a pipe wrench on the yoke. I picked up a 25" breaker bar and put a 2' pipe on it with a 1 1/8" socket. All that got me was sore, tired and swearing. The breaker bar was bending.
I called around town to places that rent tools but no one rented an impact wrench. At least, not one larger than what I already have.
So I called my local Tuffy and they said bring it over. They had me back my Jeep up and they took it off in about 2 seconds without even taking it out of the back of my Jeep. Turns out that I simply needed more persuasive tools. Also, they didn't charge me anything for doing it.
Once the nut was off, I checked the pinion threads and the nut and it definitely wasn't staked. It was just really, really on there.
So now I enter the land of pullers and punches...
