What should you check about the kingpin during the vehicle inspection?

When inspecting the kingpin during a vehicle inspection, it is essential to confirm that it should not be bent. A straight and properly aligned kingpin is crucial for maintaining the stability and safety of the vehicle, particularly in how the fifth wheel connects to the trailer. A bent kingpin can lead to improper coupling, difficulty in maneuvering, and even pose a risk of the trailer coming loose while in transit.

A kingpin that is undamaged and correctly positioned ensures that the weight of the trailer is properly distributed and that the hitch operates as intended. Any deformation in the kingpin could indicate underlying issues that need to be addressed, as structural integrity is vital for safe operation. In this regard, conducting a thorough inspection of the kingpin is critical for overall vehicle safety.
