The spindle knuckle (also called car knuckle or steering knuckle) is the structural component that bolts to the suspension. The wheel hub assembly sits inside the knuckle and contains the wheel bearing, allowing the wheel to rotate. Some vehicles use a combined spindle knuckle with hub bearing, while others require separate spindle replacement and wheel hub replacement.
