Finally did the new kingpins in the truck. Just drove it and its all good. The drivers side had basically no play in it but the passenger side definitely had some noticeable slop but not terrible. Its all fresh now though. Used a old set of pins/bushings/bearings that I scored on ebay and even the correct factory service tool to ream them true and to size. Im very happy with the end results. Not bad for my first ever set of kingpins. Im very close to being 100% done with everything on this project. I know it will always require some attention but my to-do list right now is basically 3 very minor things to take care of.
