This steering knuckle pin is the pivot element that connects the axle housing to the steering knuckle assembly. It allows the knuckle to rotate when the steering linkage moves, translating driver input into wheel direction change. The pin fits into the kingpin bore and carries the vertical load of the front axle while enabling smooth rotation. Wear on the pin or its bearing surfaces produces free play in the steering, leading to imprecise control and uneven tire wear. This original AGCO part is machined to the same diameter and length tolerances as the factory-installed component, so it seats in the bore without requiring shimming or reaming. On installation, ensure the bore is clean and free of burrs, and apply the specified grease to the pin before inserting it into the knuckle.
