I've read all the posts about swapping kingpins but still have questions. Three different shops have told me I should swap them out but i'm at a loss. Even with the suspension in the air, the front end doesn't have any play. Should I just lube the chassis and see what happens? In my tool scrounging I've found a C clamp with a hole in one end that was used way back when to push the kingpins out from the top. You simply latch it on and start turning. The pin comes out the hole in the bottom.
