How does a kingpin axle work?
The role of the steer axle kingpin is to maintain steering geometry on the vehicle as it provides the ability for the wheel ends to turn the vehicle left or right. Being that the steer axle kingpin is a critical component, service and maintenance must never fall behind.
What's a kingpin mean?

1 : the chief person in a group or undertaking. 2 : any of several bowling pins: such as. a : headpin. b : the pin that stands in the middle of a triangular arrangement of bowling pins.
What does a king pin do?
King pins, the bushings that encircle them, and their related components are essential for proper steering. They connect the steer axle to the steering knuckle, supporting the steering geometry and allowing the wheel ends to turn the vehicle.
What is a kingpin on a trailer?
The King Pin connects the gooseneck to the tractor by locking into the fifth wheel. The Standard King Pin is located 15" back from the front edge of the gooseneck and is welded to the fifth wheel plate. A Two-Position King Pin is also available as an option for most ROGERS semi-trailers.
How do you read a bubble gauge?
Read the line nearest to the center of the bubble. Each line is 1/4º. To read CASTER first turn the wheels 20º to the right when setting the RF and to the left when setting LF. If you don't have a set of turn plates you can use the angles machined on the corners of the gauge as a reference.
What is a kingpin on a truck trailer?
The kingpin (also king-pin, king pin and k pin) is the main pivot in the steering mechanism of a car or other vehicle. The term is also used to refer to part of a fifth wheel coupling apparatus for a semi and its trailer or other load.
How is kingpin offset measured?
The king pin offset is defined as the distance between the center of the wheel and the crossing point of the king pin axis and the wheel spindle axis.
What is the kingpin inclination?
Swivel pin or kingpin inclination is the lateral inward tilt (inclination) from the top between the upper and lower swivel ball joints or the kingpin to the vertical (Figure 10.3).
Why are the kingpin inclined?
On current suspension systems, the kingpin is set at an angle to the vertical plane when viewed from the front or rear of the vehicle. This angle is known as the king pin inclination. The purpose of the KPI is to produce vertical displacement of the vehicle in during steering in an upward direction.
