Just got m '54 F-100 back from the shop. Had new king pins put in, didn't have time to do it myself...
Makes a world of difference in the steering. With my rebuilt steering box and now the kingpins, it really steers easy, even with the radial tires. I would recommend anyone that is contemplating putting in a modern power steering setup drive someone's truck with all the straight axle parts rebuilt or replaced.
Anyhow my question is this: The truck does not turn as sharp as it should. These old trucks were known for the sharp turning radius. What do I need to do? The shop manual says the steering stop adjustment is 2 1/16 left and 2 1/16 right. Did the mechanic not put the king pins in right? or adjust them right? What shall I tell the mechanic? Is it a simple matter to fix this?
I am not able to cut into my garage or parking spaces like I used to...
thanks,

Check that they cut the end off the bolt that holds the King pin in.
If the bolt is sticking out too far this will act as a steering stop. just my thoughts though I may be rambling.

Found the problem, I think. It happens when I cut to the left. The end of the bolt on the left end of the tie rod is sticking up too high and it hits the spindle arm on the left side. Either the bolt was pointing down before the king pins were replaced or it didn't hit before. I also had the front spring bushings replaced. This may have changed things also. Should be an easy fix.
Thanks for that info. Not sure if it will pertain to my '51, but it turns real sharp to the right but not nearly as sharp to the left. I thought maybe the pitman arm was not on the steering box right, but it's splined so that if I take it off and turn it I have to turn a full 1/4 turn, by then I figured it'd cut too far left instead. Just need time to lay underneath it and stare at it for a while I think.
My 52 M1 is the same way - i think this is intentional to prevent the back edge of the driver side tire from rubbing on the drag link when turning left.
That's what I did. got on the creeper and laid underneath the truck with the wheels straight and then cut left and right and stared at all the parts. I am not an expert on '48-'52 however. That may be a feature that they improved on '53 model and up. They were designed to have the same turning radius both left and right.
