Ok,took my king pins out last night,and I think I might have a problem.I tried the new king pin in the I-beam and it has a small wobble in it,I still have to push it in using a rubber hammer but after I get it in I can get it to move alittle in the I-beam.Do you think this could be a problem or is the lock pin going to tighten it up?

48 one ton,

It is a problem and needs to be repaired if you are going to do it correctly. Oversize king pins would be required and the axle eye would need to be reamed or machined oversize to accept the oversize pin.

I have just been through this. You have a couple choices,an oversize king pin or a sleeve to bring the axle back to the size of a standard king pin. Or you can find another axle that will accept the new king pin and not wobble. My original axle was pretty much a disaster, so I found another one that wasn't nearly as bad. I still had to have one side sleeved, but it is like new now. They also knurled my spindles so the bearings will fit snug.

You will probably have to remove the axle and take it to a machine shop for this work. While you have it apart, check the spring shackles and rear spring bolts for wear and being loose, as well as the tie rod ends. I am also replacing my flexible brake lines and cleaning up and painting everything.

This is a lot of stuff, but may be required to give you a good functioning and safe front end.

Thats what I was afraid of,well I already have the new king pins and the other side is ok so I'll talk to the machine shop and see what they say about puting a sleeve in it. Thanks

I've just been through this also. I took my 51 3100 to a shop that mainly repairs straight axle big trucks, and the old guy who owns the shop told me that usually it's the axle that wears out instead of the spindles, which I assumed were shot. They had to bore out and resleeve the axle, and was able to use the spindles as they were.
I would stay with the stock king pin size instead of oversizing, oversize king pins aren't as easy to find.
