There was a significant amount of play so I am considering going to a .010 oversize kingpin. Any idea how you determine if you need the oversized kingpin? The old bushings in the spindle feel tight with the kingpin off the truck.
Thanks! | | |

As long as the bushing fits tightly in the spindle, it will be ok. The 1/2 tons use floating bushings, that don't have to be reamed to fit the pin. The larger trucks have the bushings pressed in and then they are reamed to fit the pin.

The bushings will still have the same O.D. has standard. If your standard kingpins fit snug in the axle ends, that's what you need. Someone a few years back had a post about making oversize bushings to repair worn spindles. It may be in the Tech section.
