Well....this ole nut is getting interesting now. I suspect it has never been off in nearly 50 years. No sign of rust but I tried the 1/2 drive Craftsman Air Impact that I had thinking perhaps...NOT. Then I figured I needed a work out so I did the BIG pipe wrench lever lock under the leaf spring (sorta like the manual shows) with a big breaker bar. NOT, I stood my 200 pounds on it and jumped( no bed on frame) NOT. Then I got missle lock on it with the BIG HAMMER on the breaker...NOT. I am going over to buy the BIG Air Impact now cause I love a challenge. Big Nut-2 Ralph-0
