Mama,

Replacing kingpins generally is not that difficult, if you have the proper tools. However, replacing king pins on a a 50+ year old commercial vehicle is another story. Usually involves much hammering, probably some heat and a fair amount of colorful language. The disassembly will be the issue. Reassembly will be pretty straightforward.

The 4104 manual I have describes the process in pretty good detail in the Section 1, entitled Front Axle under Steering Knuckle removal. There is a cutaway drawing of the knuckle, but no diagrams. If your manual is missing this section, let me know and I'll scan the pages and email them to you.

I would recommend taking the knuckles to a machine shop to have the new bushings installed, since they should be pressed in and will need to be reamed to size after installation.

A parts book is extremely helpful on jobs like this because of the exploded parts diagrams.

If you don't have one get one.

Great suggestion, Gus.

Mamacakes: I have a 4104 parts book, as well, and there is a nice exploded view of the Knuckle assembly. I can scan that page for you too, if you'd like.
