Did the other side and that went as smoothly as a king pin job will go but this side seems to be pretty frozen up. In fact, it takes a little effort to turn the spindle by hand (without the steering arm hooked up even!) Now I see why my steering was such an effort! | | | | | Joined: Mar 2005 Posts: 627 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 627 | I eventually had to get a helper to support my axle across an anvil so I could get a full swing with a 12 lb sledge hammer. That was after 2 weeks of heating, cussing and beating with a smaller sledge. Good luck!

What are you having a "hell" of a time getting out, the king pin or the tapered bolt that locks it in? You already did one side OK so
I'm sure you know the lock bolt is tapered and drives out from the threaded end. Is it the king pin that is frozen in the axle eye? These two items can become one and require much coaxing!! Heat the eye all around, wait several minutes and spray with WD-40 (or whatever) then grab a good pnuematic air chisel with a flat nose tool and,
using all your weight try driving the king pin down from the top! This has to work cause there ain't no plan B!! You must visualize the king pin moving in your mind !

Have heated it up on both ends and in the middle... have used a good penetrating oil.... have used a heavy sledge... have used a pnuematic air chisel... have cursed a bit... OK a lot... We'll go back to it today.
Why candle wax im4racin??? | | | | | Joined: Jul 2002 Posts: 188 Member | | Member Joined: Jul 2002 Posts: 188 | Larry, 25 years ago I had the same issue with one keeper on a 46 3/4t. After a week I gave up, pulled the axel and had the keeper pressed out at a machine shop. Cost me $10.00. I didn't have a torch, so i soaked the U-bolts in paper cups with tranny fluid for a few days, borrowed a 3/4 drive rachet with a 3' pipe on it and got everything off and 2 the machine shop.
Good Luck! | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | I had to drill mine out. I took my time and when I got near the wall of the opening, I quit. The remainder of the pin had no strength and I was able to drive the kingpin out. Now, moving the kingpin was another story. I had better success when I used a hardened wristpin for a drift. | | | | | Joined: Feb 2005 Posts: 531 Shop Shark | | Shop Shark Joined: Feb 2005 Posts: 531 | I ended up drilling the sucker out yesterday... took 2 1/2 hours. But it's out! The king pin is pretty sealed in so that's next tomorrow.
Thanks for all of your suggestions! | | |
