1972 Ford F100 - Stop Gasser!

The beauty of opting for the '65-72 F-100 disc brake conversion offered by Classic Performance Products is that they have spindles that have been refurbished and black powdercoated, followed with new brake rotors and rebuilt calipers.

Also included are new wheel bearings, seals, brake pads, and a new kingpin kit. Before installing the new kingpins, we checked the kingpin bushings and discovered that paint overspray was interfering with a press fit. We cleaned the kingpin bushings with a brake-cylinder hone and tested them for fitment.

This tool is for extracting the cotter keys found on the nuts throughout the twin I-beam front suspension. Lineman pliers or dikes also work well.

We found LMC Truck in Lenexa, KS, carries a complete line of replacement parts for Ford twin I-beam suspensions. These are their polyurethane bushings that upgrade the original Ford rubber parts.

Here's a shot of the stock Ford rubber bushings in comparison to the LMC upgraded replacements.

We found the best way to service a Ford twin I-beam frontend is to remove it from the truck. Afterward, it was much easier to remove the original kingpins.

Extreme care needs to be taken on parts that have to be reused. The last thing left to remove the twin I-beam frontend were the pivot bolts.

We soaked the Grade 8 pivot bolts with Rost-Off before removing the nuts retaining them.

To protect the threads, we used a brass hammer to drive the pivot bolt flush with the frame, and a 1/2-inch round brass drift to drive it the rest of the way out.
