| Trying to replace kingpin bushings and pins on a 12,000 lb axle. Not getting them to budge with a hydraulic jack underneath. I found a "tiger tool" on ebay but they are pricey, 1600 to $2000. Not supposed to heat. I am thinking of making a bracket for a hyd jack. Right now I am just lifting the truck. Any ideas? On this site I suppose I should ask for good ideas. I do have the tapered retainer pins out. The instructions say to put the new pin in from the top so it seems the old one should go out that way. |

Pierce county WI | Air hammer, 10# maul. Spicer axle? If you have both retainers out and the end cap, pound it down through. Look on the bright side, your axle isn't so worn out it falls out. Oh- try turning the knuckle each way if it still isn't going, they get worn funny. Come to think of it, maybe try rocking it too.

Soil | Lose the jack , set the pin on something steel set on concrete. Use the weight of the truck to help,with a big sledge hammer. Have used heat on axles several times didn't seem to hurt anything. A jack has some cushion effect when trying to use it as a block |

I have probably changed 50 sets of kingpins in my 15 years as a Diesel Mechanic. I have heated many axles cherry red, and pounded the living snot out of the pins to get them out and never had any axle fail. A rosebud is your best friend here.

Sparta, WI | Here's my homemade remover. There is a hole in the top plate (hidden by the aluminum piece in pic) slightly larger than the diameter of the kingpin for it to come up through. I have since added a little reinforcement to the top plate. Works great. Only problem is I have now done kingpins in every truck I own so I don't need it anymore lol. Guess it's time to buy more trucks.

west central illinois | That's one of those jobs I find it easier to write a check than to screw around doing it myself. |

| The contraption pictured is just what I was thinking of building. |

Sparta, WI | Build one if you have the resources. I had to have the top hole cut somewhere else because I do not have that big of bit for our mag drill but the rest was simple. I only used it on the truck pictured because that's the last one I've needed it for but after a lot of pounding and swearing, I built that, and it popped them right out. I'm not a metallurgist, but right or wrong I do know that extreme heat changes the properties of any metal, so on any truck with my name on the door, I will use that as a very last resort on things such as axles.

| You should think about going intobusiness selling those things. It looks better than what is being sold on ebay for $1600. |

Dearfield Co. | I have chain pots buried in the floor . I just chain them down and air jack them out. No torches either since I wont use the nylon over brass bushing sets that the nylon wears out and the brass embeddes into trekking pin
If it has the screw in plugs on the top and bottom of the king pin be extremely careful doing anything with them since those threads are tender and its costly to screw them up. I can't believe how many we see that are welded into the spindle |

I can't believe how many we see that are welded into the spindle That's what the aluminum plate is for. I put that between the top of the spindle and the top plate of my tool until the initial "pop" to cushion the top of the axle. I then take it out and push the kingpin up through the hole. I agree on the nylon bushings, they are junk. I have stared using the Kaiser no ream spiral bushings and time will tell how they are but the nylon was only lasting me a couple years. |

| It should be obvious how much pressure a 20 jack will apply but I wonder how much the threaded rod style would do? |
