How do you install kingpins on a 1976 Ford f-100 2wd?

Answer 1

The kingpins are the about 1" by 6 inches and link the spindle housing to the axle. One pin per side and they are held in place with a key bolt at about half way along its length. The kingpins sit vertically in their assemblies.

To remove the pin: first remove the retaining pin by backing off the bolt and removing the bolt and washer then driving out the retaining pin. If you will be reusing any of these parts take care not to damage them by hitting them with a steel hammer.

Next remove the grease caps located on the top and bottom of the kingpin. Finally drive out the kingpin. This is the step that causes the most problems because of the heavy rust that develops fromimproperlygreased or otherwise neglected Kingpins.

Aftersuccessfully removing the pins, taking care not to damage the brake hose (best to just disconnect this hose). Prepare to install the new pins, shims, bearing, bushings, caps and zerts.

The brass bushings will last longer but require honing because they are manufactured by rolling a sheet of brass and are therefore not perfectly round. Honing them (done by a machine shop) will ensure proper operation and wear. the nylon alternative is cheaper, does not last as long but can be installed at home. The bearing goes on the bottom between the spindle and the axle. Sometime shimming is necessary to eliminate any slop in between the spindle and the axle.

put the bushings in, place the bearing, add any necessary shims, and drive the new pin into place. Finally recap and grease with a grease gun.
