HOW DO I GREASE MY KING-PIN?

wrote

If you don't have even the most basic knowledge of your truck to be able to point to the kingpins (there's 2 of them), then please get off the road before you kill someone, or leave the maintenance to someone else.

Take it easy on the Caps Lock button. A king pin is a design that predates ball joints in the steering axle of a vehicle. It is still used on heavy duty solid axle applications, presumably for its strength and simplicity. Anyhoo, this is what allows the front wheels to pivot left and right. Look in the area that ball joints would normally reside (in and around the steering knuckle), and you will see the solid pivot shaft -- and hopefully grease fittings that you need to address. RE: lifting the vehicle: I would assume that you would simply lift one corner at a time underneath the leaf spring seat (if so equipped) unless you have a large frame jack that could handle the entire front of said truck. Use suitably rated jack stands under the frame for additional safety.
