Trying to get the King pins out of my 55 F100, what is the best way, take the whole axle out and have them pressed out or try to do it in the truck. Is there an adapter for this to press them out, in the truck, or do you just beat them out.
On my 77 F150 I was able to get them out quite easily since they had evidently been well greased during their time in my truck. Did you remove the lock pin from the spindle? If so, you could try a large brass drift to drive them out. Another trick I have heard about is after you remove the upper and lower caps. Find a long piece of metal that fits into the king pin hole like a large 1/2 socket extension for example and place it in the bottom king-pin hole and have someone lower the truck down until the weight of the truck is on the socket extension / king-pin shaft. If your lucky the weight of the truck will break the king-pin free, so it can be removed. If all else fails you remove the entire assembly from the truck and have them pressed out.
Support the bottom of the spindle on something solid like a 40# block of iron so the hammer energy is transmitted to the pin and not the suspension. Add some heat 2-300 degrees I like propane so your penetrating oil just starts to boil and soak it. Use a brass drift to prevent any swelling of the pin.
Not so much into getting them out, as the new bushings will have to be reamed to size. If you don't have reamer avail. in the long run you would be better off removing the axle and having the work done. PS don't forget to sign up in the NY Chapter.
No need to remove the axle as the bushings are in the spindles, once apart have a shop that knows how to press out, install new and ream bushings with the correct king pin reamer. In other words take spindles with king pins and bushings to a shop unless you can do it yourself.
I'm lucky as I made a stepped drift to remove and install bushings plus own the proper king pin reamer with a pilot, this is for 68 and 69 trucks.

Has there ever been a post with a detailed photo shoot of the change over. I recently gave my 77 E-150 to my brother in B.C. Of course he had to have it safety inspected. Buggers said he needed the pins changed. Bro has no dough. Thats why I gave him the van. Needing a do it yourself how to. PLEASE. He really needs the truck on the road. And my Sask plates are still on the rig!!!!!
If he isn't going to drive a lot of miles go the easy cheap route and install the nylon bushings. Remove the old metal backed bushings, install nylon by hand and reassemble everything. Keep them lubed. Make a stepped drift or collapse inward the old bushing being careful not to score up the spindle bore.
