    I had to remove seized kingpins on a '56 GMC truck when I was 20. All I had was propane and a sledge.
    I about killed myself, but i got it done. Today, beyond any question, I would remove the axle, to level the playing field.
    Once of the nice things about Kevin's method is the vibration set up by the air hammer. Heat and vibration are the way to loosen the fine rust that has locked the pin in.

    I once freed up a frozen dizzy on an old cadillac by aiming the needle scaler at the base and let'er rip. No damage was done to anything (just needles), but the vibration was incredible and that loosened it right up

      Time to pull the axle,not only is it easier to do the work but bear in mind axles do bend,last thing you want to do is beat a king pin out and alter your camber at the same time...I know it sucks after your diet coke run but draw a breath and pull it down,check everything and do it right,in the end you.ll be glad you did.

        Steel and iron are porous; and believe it or not, old "solid" rust is porous.

        Old tight and dense compacted "porous" rust requires a special fluid to penetrate it.

        Only few want to try this vintage, old time Mechanic-In-A-Can rust penetrating remedy; i.e., mixture of 1/2 Automatic Transmission Fluid + 1/2 Acetone in a "Glass Jar", but it works if applied often and allowed to soak for a few days.

        The Glass Jar is often necessary to "see" that this mixture is "thoroughly" mixed prior to applying same. Sometimes some ATF's & some Acetone's do not want to mix; hence, one has to shake the jar immediately prior to application to "see" that one has this uniformly Pink colored vintage solution.

        This homemade mix works when one can see it is Pink.

          I agree pull the axle, you still have another side to do. As Chief mentioned above, you can then go over everything else while it's apart. You can bet your dollar that there may be more issues than the king pins.

            After seeing those bearings you can bet on it, now is the time to do the whole front end springs and all while your at it and check that front crossmember for cracks. When you are done you will have piece of mind.

            New Springs, cross member is solid, new tie rod...new everything but axle, king pins and actuating arms and they are in decent shape. New brakes and shoes, new drums, original backing plates with new brake components. Hell, its all new or rebuilt. Just read something about king pins and did the test. Someone with my limited knowledge did not know to check. Now if you want to know how to make sewage water into drinking water I can help you with that....LOL or sell you the equipment.

            The extreme heat from the shop fire might loosen the king pins.
            I don't suggest this as an alternative method though. Lol. Jeff

            That is because the worn out side was in there beating itself up.

          Once you are done, be certain your grease pathways are totally clear. I'd be putting in new grease fittings. You gotta keep king pins greased well and often. If you do, they will last a long time. Jack up the car and turn the wheels left and right as you are greasing, grease the hell out of them, and do it often.

          Also, check the tightness of your lock pins periodically, they like to loosen up. I whack 'em from the front then take up what I can with the nut. If you try to tighten the hell out of them with only the nut you can strip the threads

          The press is scaring me...lot of creaking. (like rust cracking or my axle) Shattered a socket and now using other pin with head cut off. Just hard to get a whole axle good and level so I need to use something shorter so there is no tilting.

            Sometimes i put my goggles on and a welding helmet on over them. Then i tie on my full body welding apron.. It does get scary sometimes

            You can't press using a HF socket either

            When you get a load on the pin with the press whack the axle a few times with a hammer,vibration works wonders,especially when combined with press load..

            Move your press table up to the pump as close as you can. Always press using the shortest distance. Place a strong steel cup under the spindle, this will help to steady the ASSY. I have an assortment of metal disc brake caliper pistons. I also use the cups that came with my ball joint press tool. As the pin presses it will go into the cup.

            I used my cherry picker to hold the axle while I pressed out the kingpin as I was working alone!

          FWIW, during king pin/spindle re-assembly ...... especially on an 85+ year old worn assembly::

          1. Make sure the top & bottom spindle bushings cannot rotate inside the left and right spindles.

          2. The holes in the top & bottom spindle bushings have to line up with the spindle holes for the spindle grease fittings.

          3. If either the top and/or bottom bushings in the spindles "can" rotate inside the spindle, the bushing hole can rotate with the bushing to where it will not be aligned with the spindle grease fitting.

          4. If this happens, the king pins and spindle bushings will not be able to receive needed grease lubrication.

            Wiz, seemed like you have done this before! HAHAAHA! This socket was just a stress reliever on the bottom but you guessed right. I was hold everything and do it all at once. My back will know tomorrow. I have a fellow Model Aer 30mins away who has a torch. He said he would get it out or melt the axle.

        • #26
          Beauford, since you have the axle out, may I make a suggestion?

          If you lay the axle on the floor, drill the hole a bit, just enough to slide a bolt in and get a short socket to fit the head of the bolt and use that as a guide to keep the socket in place. It will help even more if you have say a 2in or 3in bolt you can add enough nuts on to fill the socket you use. This will cut down on having to hold the axle, socket, and pump the press all at the same time, and be sure to use the shortest socket possible as Mitch mentioned.

          It would also help if you were using impact sockets.

            When you get some pressure on that, use a torch and apply some heat then cool you may find it is starting to move a little that way what wiz said is good and a impact socket or borrow a snap on socket Mitch can always get you a replacement.

              Good idea.
              When I'm working in the basement, I've clamped a C clamp to the floor joist and tied a rope to it to hold a long part I'm working on.

              If it moved 1/8", I'd be tempted to hammer it back that 1/8", and keep going back and forth.

              I am thinking at this point that you are gonna need some serious heat

              The farm boys I knew back east had a trick when they needed to remove a rear tractor wheel from those long splined axles (they were long so they could adjust the wheel spacing to suit their crop rows).
              They would heat the center of the wheel hub with O/A to a good blue color and then walk away until the next day, when the wheels would just fall off. If they tried to hammer them right after they were heated they wouldn't budge

                  Mitch I am sure you have a full size O/A setup. I'd like that but we have one of those mini-kits and since we seldom need that much heat, it works out real well. I keep some spare bottles of each gas, and I don't have to worry about storage space for the bigger rig

                  Sometimes ya just gotta let Mr O and Mr A take over......LOL

                  Heat and quench with pressure on it won't hurt either just do not get in a hurry. This is a good time to look at the spring perch bushing as well.
