I finally got around to pulling out the I-beams and going after the kingpins. After much cursing and banging I finally got the I-beams out of the truck and was hoping that it'd be fairly easy to press the pins out with my shop press. Unfortunately, them things are really seized in there. Any suggestions for getting them out? Spraying as much PB blaster as I can and leaving them in the press overnight seems to be a good place to start.
Assuming you've removed the cross bolt, if they're worn, they should fall right out. Do you plan on installing the new ones yourself? They should be hone fitted. When I did mine, I disassembled everything and let my local shop fit and press the new ones. Perhaps not much help, but just my 2 cents.
Thanks Tony. That's the issue I'm coming up against, they're seized in the I-beam. Currently going at it with a sledgehammer and they still aren't coming loose. I might take them to a shop to do, unsure as of now. I just need to get them out first

When those things are new, they should be a tight slip to a very light drive fit in the "I" beam, but over the years that becomes a solid rusted together fit. You will have to heat the "I" beam with a torch to get them to break loose. Even though those king pins are hardened it is possible to mushroom the end, don't do that. If you use the nylon bushings they do not have to be reamer and usually last 25,000 mi. The metal ones have to be reamer or honed to fit by a machine shop that has the tools for that.
Thanks for the tips, CD. I didn't think about it mushrooming. I'll have to get something a little bigger than my propane torch to do any real heating. I'm planning on doing nylon bushings since sometime in the fall I'm going to do a CV swap.
You're not kidding Tedster, every time I look at this truck, whether it's for parts or for tools, my wallet hurts. I'm afraid I don't have that heavy duty special checkbook some gents have on here.
We need a little ND about now, don't we? I like some of his old quips. Especially that last line.

But before doing anything, you need to have EVERY repro parts sellers catalog to compare what each has, to compare prices, in order to come up with an estimate of the costs.
And whatever dollar figure you come up with, DOUBLE IT and then add 25% and this still won't be enough.
Many people grossly underestimate what a restoration costs. Some have no plan, tear the truck all apart without taking pics or labeling where the parts came from.
But, when reality sets in, they find they can't afford it, lose interest. The loose parts are piled in the bed, the truck sits forlorn or is sold for peanuts as a "basket case" or goes down the road to Valhalla.
You think you bought an old truck, but what you actually bought is a hobby...and hobbies tend to be expensive.
That's some good stuff right there. Thanks for sharing it, that last line sure is particularly applicable. Thankfully I bought it for the purpose of being a hobby. I'm just having to move at a bit slower pace than some
@TA455HO Where did you get that?? Hadn't read that one. On my old beast the kingpins and tie rod ends are probably the only thing I didn't have to replace.
I just did an Advanced Search on the Username of NumberDummy and keywords of hobby tend to be expensive in our Forum and you'd be surprised how many hits you might get. LOL.
Crop Duster is right about the "solid rusted together" description - I took my axles to a HD truck shop and it took a 25 ton press, lots of heat, and some generous swinging of
large pieces of iron until they broke loose, and they really weren't all that rusty/nasty looking - just hadn't been apart in fifty years. I'll never see them apart again - but I did put some
anti-seize on the new pins and axle bore; I doubt they got anything on the assembly line...
Managed to get them out this morning. Put it in the press and threw a towel around it just in case something shattered and I went to town and they finally moved. Used a small impact socket as the go between the ram and the kingpin. Took a bit but I had them both out in about half an hour. Now for the fun part of putting it all back together.
