I've heard too many different stories from too many different people
that now I'm confused, and really would like some credible info from
someone.
I need to find out if the kingpin used in the Twin I-beam suspension by
Ford in their 1/2-ton, 3/4-ton and 1-ton trucks from '65-'79 all used
the same kingpin. The main thing I'm looking for is the actual kingpin
diameter for each of these applications. I can't find this info
anywhere, and I've been looking for some time. The dealership won't
help, the parts stores simply tell me that there is one part number used
for '68-'74 parts and a different part number for '75-'79, but that's
all they can tell me.
Can some kind soul PLEASE help me wade through all this information (and
mis-information) and provide the specs? Thanks!!!

Why not just go to the parts store, have them hand you one of each and
measure them.

The Ford Factory parts book for the years of 1973 to 1979 F-100 to F-500 shows
about 10-15 different part numbers for that part. Some numbers/parts may have
been replaced as this is an older book but I would need more info as to what
the axle code or application might be. In any case there are no dimentions
given for any of these king pins. The Ford part number is xxxx-3111-x , X being
the unknown. need more info.>The dealership won't
>help,
I doubt that the dealership has the info you are looking for. Short of
measureing each part for each application. They did make an oversized one at
one time. hope this helps
