King pins aren't that hard. You just need a giant hex driver to get them out.

The upper bushing part. Depending on the kit you get, the king pin itself can be replaced. It just unthreads, but is torqued to something like 300ftlbs?cant remember it's been a minute since I rebuilt mine.

Take the top and bottom cover off, and removoe the bolt center in between ends. A brass punch and hammer might get it out, other wise it a press.

my suggestion is to undo the tie rods from the knuckle and try turning it back and forth. it should be able to turn with little effort.
if it takes a lot of effort there is your binding.

likely kingpins.
could also be gearbox, but generally that is only hard to return to center in one direction

The reason I’m going after the kingpins so confidently is the only thing that changes it is when I grease the king pins,

While the bearing in my current column sucks, my old auto column as tight as a nuns k*nt and it had the same problem

King pins take a special reaming tool. When the new bushings are pressed in they shrink a little bit. This is on purpose, both bushings must be perfectly aligned for a friction free fit with no play. After the bushings are pressed in, the machine shop takes a reamer and runs down through both bushings and then tries the new king afterward to check the fit. They slowly open up the ID of the bushings till they get a perfect fit. Sometimes it's hard to find someone who knows how to do it. Big trucks still use kingpins, so they may know how to do it, but may not have a reamer small enough for your pickup.
