It is important to install the seal in the correct direction to allow the grease to flow through the bushings.

The bushings included in a standard king pin kit will need to be reamed to fit the new pin after they are installed in the steering knuckle.

Bronze is used on the inside portion of the bushing due to its anti-friction and wear-resistant properties, bronze will only become damaged if lubrication is not present. Steel is used for the outer portion of the bushing to allow it to be pressed into the steering knuckle without deforming the inner bronze area. Standard king pin kits use solid bi-metal bronze and steel bushings. You can avoid a machine shop using a spiral bushing kit so if you are servicing your own truck this is the kit to use. Spiral kits are the ideal kit to use if you do not have the capability to press new bushing into the steering knuckles and ream them to fit the pins. These bushings can be installed by twisting into the spindle using an installation tool and they do not require reaming. Spiral bushing kits use a coiled, spiral-shaped bushing. There are two main options for king pin kits to accomplish the job of replacement. Performing a king pin rebush job is a major undertaking so it is best to be prepared for the task with a replacement king pin kit.
