Kingpin replacement #1

I'm in the process of re-assembling my front suspension. When I went to put my driver's side kingpin onto the outer fulcrum pin, it wasn't even close to fitting snugly(when I was taking it apart, I hoped that only the fulcrum pin was worn...)
Is it possible to replace only the kingpin without buying (and reaming) new bushings? My kingpin is still good and tight on the swivel axle bushings.

Do you mean the lower fulcrum pin? If the cotter was not installed right and the kingpin weren't locked to the fulcrum pin, then the kingpin was allowed to wear against the fulcrum pin. That would have allowed the hole in the kingpin to wear and become enlarged thus making it unusable. The bushings in the swivel axle sound like they are in good shape. Kingpins are cheap. If you have to buy a new one, it shouldnt cause any extra difficulty or cost you too much.

Yes, the cotter must not have been installed right or something, so the hole in the kingpin is more than 1/8" larger than it's supposed to be. That's exactly what I wanted to hear, I can't really afford new reamed kingpin bushings right now.
