all i know is i replaced the kingpins on the 53 back in 88 with the factory bushings. they worked great for 18 years or so. mind you it spent a lot of time parked. i do remember how hard it was, about a day of hammering with the biggest hamer my dad had (he is a forklift mechanic and he has some big ones). sort of like chopping a cord of wood!

I have replaced the kingpins in my other truck. I had the axle out so it wasn't to bad. These kingpins with the bearings are supose to make it steer easier.
