Well I finally got it done. I broke 2 half inch ratchets, my tourque wrench and my breaker bar trying to get the castle nut off the stub axel. What a pain in the ass. The two auto parts stores with loan a tool programs did not have any impact wrenches.
A guy next to me heard what I was doing and asked where I lived and then he told me he lived about 3 blocks from me and would be right over with his impact gun.
He came over and zapped the nut off in about 3 seconds. He showed me where to give the axel a good whack to break it free from the hub and not screw up the threads, he knew how to get the hub off the knuckle pretty easily. We put the new hub assembly on and he tourqed it down all in about 20 minutes.
He was a complete stranger to me yet he took time out of his day to help me out. In thanks my wife sent a big box of freshly baked xmas cookies and I gave him a big hunk of elk salami which really thrilled him.
While talking to him I found out he grew up on a farm in Iowa and had been in the military with 3 tours to Iraq and suffers from PTSD. I thanked him for his service and for bailing my butt out.
It restores my faith in my fellow man to have an experience like that.
