How much PSI does it take to release the king nut on the rear hub? What's a good trick to keep the whole thing from spinning? What sizes are the shock bolt & nut?

Crap, I was going to bust those apart with the air gun before you left. I forgot. If nothing else, throw them in the back of your car and head down to a tire shop (or any other shop) and ask them to zip 'em off.

You'll need a 19mm socket, just in case they don't have one. And something other than 1/4" drive.

Yeah, I spent about 45 minutes realizing that I could basically get nowhere...
