In general, a steering knuckle pin is part of the pivot joint at the wheel end of a steered axle. It lets the wheel end turn for steering while the joint stays tied to the axle. Because it sits in the steering path, a worn or damaged pin can affect how the machine steers.
Common signs include excess play or looseness at the wheel end, steering that feels sloppy or wanders, knocking or clunking when turning, and uneven tire wear. These symptoms can also come from other steering components, so inspect the whole wheel end and follow the machine's service manual for inspection and replacement.
