The steering knuckle is a critical front suspension component that houses the wheel hub and bearing, connects to the upper and lower control arms via ball joints, and links to the steering system through the tie rod end. Replacing a worn or damaged knuckle assembly restores proper wheel alignment, smooth steering response, and consistent handling. A four-wheel alignment is recommended after installation.
