The right front tire was at an angle. Towed to mechanics he says might not be able to find oversize King pins......the LH side was done five years ago and they found pins. Can anyone tell me who still has oversized King Pins. 3100-235-1954 orginal front axel. Thanks for your help!

Oversize kingpins are used for problems with the axle bore. It is very unusual to do the kingpin on only one side of the truck. Maybe your mechanic could give you a little better explanation of what he thinks it needs. | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | A king pin discussion in the engine shop? What's up.

Without seeing photos....you got pics? I would guess that the bushings around the king pins are worn out or gone, or you've got a spindle problem as Fred has noted. Pics would REALLY help with diagnosis. Both king pins need to be replaced as a set, right and left. Suspension parts as a rule should be replaced in sets whether it is front or rear. Look at this as a job per axle.

I don't have pictures because it was towed. I'll ask about doing both sides. I've never had to do kingpins. Where is a good place to buy them..Napa....Auto Zoned Out.....O'really....?

If the kingpin is tight in the axle, you do not need over-sized kingpins. You will need standard sized kingpin kit. Most of the time you only really need the bushings, but they don't sell them without the kingpins.
You will need to check the bores in the spindle where the kingpin bushings go to make sure that the spindles aren't worn excessively. You can use your new bushings to see if they wobble in the spindle bores. If they wobble, you will need to find a spindle in better condition.
