So it is up to you, do what you can and then take the cleaned up pieces to a machine shop for final fitting or take the whole front axle to the machine shop and let them overhaul it for you, hope that helps. | | | | | Joined: Jan 2000 Posts: 2,074 'Bolter | | 'Bolter Joined: Jan 2000 Posts: 2,074 | Actually the kit for those king pins should come with new push in bushings that are pre sized, no reaming necessary. My old 30 Chev was the last car I had to have king pins reamed. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | That is correct: 3100 (and, maybe 3600) trucks had "floating" king pin bushings. No bushing reaming is necessary. If a king pin in loose in the axle, the axle would need to be reamed for an over-sized king pin - matching floating bushing would come with the oversized king pins. | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | 3100 were full floaters, no reaming necessary. 3600 pressed into
spindle and need to be line bored (honed) by a machine shop to
fit kingpins.

My 50 3100 is a little loose and thought they would need to be replaced. Some are standard, some oversize. | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Well...you'll need to measure to figure out what's worn and
what's not. If the brass bushings are the only thing that's
worn them that's all you need to replace. If the spindles are
worn then they need to be reamed and over size bushings used.
