Try to get a pressure washer up in there and clean all the grease and dirt out of the area. I found mine when I had a sharp clunk occasionally on sharp turns, and the 9 inches of free play in the steering due to the steering box flopping around.
Funny you should mention that. I just bought another Highboy, it has factory springs, and it leans to the driver side. This is not the first one I have seen that leans. I would imagine that the rear springs may have an effect on the trucks stance, as well as the front. As springs get old, they lose their ability to hold tension. Could also be body mounts that have crushed and are busted up.
I guess if the body lines are all straight, it would have to be the springs.
my 77 F250 Highboy just went through frame off restoration. New body mounts, new radiator mounts, and new front springs. but still leans 1 inch lower on the passenger side. We are springs are original. The bed leans about half inch on the passenger side.
Any chance the truck was wrecked before in its past life? Was the frame measured for being square during the frame off? Where is the 1" difference being measured from? The bottom of the frame to the ground or the top of tire to bottom of the fender lip? Did it have the lean before the restoration? Did the guys that restored it talk to you about excessive body shims or having a hard time with the body lines and gaps?
My whole '77 didn't lean, but I did set out to correct the slight droop of the right side cab as viewed from the rear above the bed, and in the Dent alignment. I knew it was a hair off since 1986. After measuring from frame to cab I realized that in 1977 when built, the right rear cab bushing was pulled down a hair too much at assembly, a 0.221" thick washer between the top of the bushing and the cab floor cured it perfectly. Now on a hard surface in one plane, no twisted pavement, it's as near perfect as I could wish for.

thank you for the suggestion of the measuring of the frame. I will do that and see if I can pinpoint the problem. I know that if you start shimming, that can turn into a real circus.
