Introduction The steering knuckle is one of the components that make up the automotive steering system. It contains wheel hubs (or spindles) and attaches to the suspension and steering components of a vehicle to transfer the movements of a steering wheel to the front wheels. Critical to front suspension safety and stability, the component requires quality surface finishes, precision radii, and perfectly machined flatness.
