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.
Q. How much play should a kingpin have?
“When [the steer axle kingpin is] new, they’re going to have about three to four thousandths of an inch of play,” Ayala says. “It’s not a rule, but that’s in general terms. Once it hits the ten thousandths [range of] movement, those tires are going to be wearing out fast.

Q. What is a Sunnen honing machine?
Honing machines offer an ultra-precise machining procedure trusted by job shops and high-production manufacturers to create parts that perform at the highest levels of speed and efficiency. No boring or grinding process is capable of delivering such fine levels of roundness, straightness and surface detail.
Q. How does a Sunnen hone work?
How Honing Works. The honing process uses a set of engineered abrasive stones arranged around a tool or mandrel. The tool spins as it is stroked in and out of the bore, while at the same time the abrasive stones are expanded against the wall of the bore.
Q. What does a honing machine do?
Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish.
