Steering Knuckle

Steering knuckles are pivotal suspension components connecting the wheel hub, bearings, and steering system. Positioned at the outboard end of the suspension, they facilitate both wheel rotation and directional control. These forged or cast components house wheel bearings and are attached to control arms via ball joints or bushings, enabling suspension movement and steering input. Knuckle designs incorporate mounting points for brake components and often feature integrated dust shields. Variations exist to accommodate different suspension geometries, including independent and solid axle setups, and may be constructed from steel, aluminum, or ductile iron.
