I have a king pin kit from The Filling Station. I checked the OD of the bushing and it is .858. I checked the spindle bosses diameter and they are arround .835. I don't know how much I should hone the bosses before I press the bushing into place.
Thanks

0.023 seems a bit too much to me; especially if you need 0.001-0.002 for a good press fit on the bosses....I have never done more than 0.006 to 0.008 and had a good pressed fit. Perhaps someone else will have a better idea.

I have never seen this much difference. I assume I would have to bore the spindle boss to get it down to soemthing workable. I thought maybe I was not understanding something here.

I would give the filling station a call , as your kit is from them. I do not find any instructions on their website instructions for fitting the kit about having to further ream out the spindles to fit the new bushes. There is a reference to the practice of reaming out the axle to fit oversize king pins, but not the spindle itself.
Maybe some one has oversized your spindles and fitted sleeves into them which now are too small for the new bushes.

Usually .001-.002 thou per inch of shaft diameter .I would not touch your spindles. You can have the bushings machined to get them to the correct interference fit. shoot for .0015-.0025.
Then you will have to hone the inside diameter to get the pin to fit in. A good machine shop should be able to help you out.

Once you have the bushings to the correct size putting them in the freezer overnight will help when installing.

I agree with Jack, do not touch your spindles. I installed a king pin set from the Filling Station a few years ago without any issues like your talking about. Two possibilities, someone has done something to your spindles, or the bushing from the kit are the wrong size. All you should need to do it press the bushing into the spindles and then hone/ream the bushings to the correct size.
Do the bushings fix onto the pins out of the kit?
