What characteristic is true for a kingpin in a steering system?

A kingpin is a crucial component of a steering system that serves as a pivot point for the steering knuckle. One of its inherent characteristics is that it can be tapered or straight. The design can vary depending on the vehicle and the specific engineering requirements of the suspension geometry. A tapered kingpin typically aids in maintaining alignment and stability during steering movements.

The ability for a kingpin to have either a tapered or straight design is essential because it impacts how forces are distributed through the steering system and how the vehicle handles during operation. Therefore, the understanding of kingpin design helps technicians assess steering performance and make informed repairs or replacements.

In contrast, the other choices do not accurately define the characteristics of a kingpin. Frequent lubrication is typically more associated with components like bearings. While the pitman arm is related to steering mechanisms, it does not connect to the kingpin. A kingpin should allow for controlled movement rather than no movement, as it needs to pivot to enable steering.
