What is a Truck King Pin?

King Pins are the connection between your steer axle and the steering knuckle on heavy-duty, medium-duty, and older light-duty trucks with a straight axle. The king pins themselves are large, hardened steel pins that are centered in the axle beam. The king pins protrude out of the axle on the top and bottom where the steering knuckle wraps around the axle and king pin. The steering knuckle contains bi-metal bushings which wrap around the king pins and maintain a tight clearance to prevent steering play. The king pins and bushings manage a large amount of force while holding the knuckle in correct alignment.

What causes King pin wear?

King pin wear will occur from a lack of maintenance or physical damage from a collision. In an ideal scenario, the king pin and the bushings will never make contact and a fine film of grease will act as a protective layer. If the wrong type of grease is used or if the king pins are not greased often enough the protective layer will break down and the softer bronze of the bushing will begin to wear away. An impact from a collision could also force the grease out and cause king pin to bushing contact but most likely other damage would keep the truck from operation and the loose king pin and bushings would be replaced during the accident repairs.

King pin and bushing wear will be noticeable as problems in the steering system since the steering knuckle is not being held in the correct alignment angles. Normally this will present itself as tire wear and a pull. The pull may be described as a wander because the camber and caster are able to freely change within the wear on the king pin and bushings. If there is a 1/8” of play at the king pin this can translate to many degrees of change in camber and caster settings that can vary with the road or steering direction. With proper maintenance, you may never need to replace king pins and bushings, but for most trucks, king pins will need to be replaced at least once in their lives.

Types of King Pin Kits

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. There are two main options for king pin kits to accomplish the job of replacement.

Spiral bushing kits

Spiral bushing kits use a coiled, spiral-shaped bushing. These bushings can be installed by twisting into the spindle using an installation tool and they do not require reaming. 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. 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.

Standard King Pin kits

Standard king pin kits use solid bi-metal bronze and steel bushings. 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. 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. 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. Standard king pin kits are typically used by shops since special tools are required to line bore the bushings in the steering knuckle. If you are self-installing, it will require the assistance of a machine shop to fit the pins to the steering knuckle.

King pin kit components

King pin kits are specific for each axle model and the kits will include all necessary components to refurbish the axle and steering knuckle. Most king pin kits will include the following items:

King pins – Large Hardened steel pins. These may be a single or double keeper (using one or two keeper bolts) The diameter and length of the pin are critical to finding the correct replacement kit. King pins are machined to fine tolerances to fit the axle precisely.
Steering Knuckle bushings – Bushings will be included that are installed in the steering knuckle. There will be four bushings, two for each spindle. The type of kit that you have purchased will dictate whether you have spiral bushings or standard bi-metal bushings.
Caps – King pin caps will be included when needed. The caps install in the top and bottom of the spindle and seal in grease while providing threads to install a grease zirc.
Seals – Seals install at the top and bottom of the king pin to retain the grease. It is important to install the seal in the correct direction to allow the grease to flow through the bushings. Incorrectly installing the seals may block grease from reaching the bushings.
Shims – Shims are used to control play between the steering knuckle and the axle. Shims will be used on the top of the axle between the spindle and the axle. Truck manufacturers will have specifications for each model on how much travel is allowable and shims will be added or removed to meet this specification.
Keeper – Keepers are bolts that have a wedge-shaped head and retain the king pins in the axle. As the bolt is tightened the wedge squares the king pin against the axle.
Thrust bearings – Thrust bearings are roller bearings that sit at the bottom of the axle against the steering knuckle. The weight on the axle rests on these bearings. Thrust bearings should be pre-packed before you install them to ensure proper lubrication.

Axle damage

In some situations, the axle itself can become damaged and the axle will no longer fit the king pin tightly. If a new pin is installed and it is loose, it will continue to damage the axle over time. Using the truck with a loose king pin to axle connection will cause the same alignment issues and tire wear that loose knuckle bushings will. Ignoring a king pin that is loose in the axle may lead to the entire axle needing to be replaced. If the damage is noticed early enough a shop with the correct tools can bore and re-sleeve the axle. There are oversized bushings that can be installed in the axle that allow you to bore the axle to fit the larger bushing and an original sized pin. This is a specialized job and not all shops will be able to complete it in house.

Both types of king pin kits are complete and will contain all the parts required to complete the install. There are several special tools required for either type of king pin kit, so it is important to keep this in mind before starting the work.
