This loaded knuckle assembly includes the hub bearing and dust shield, providing everything needed for a complete front suspension knuckle service in a single unit.

A damaged or worn knuckle can cause hard braking, difficulty turning the wheels, uneven tire wear, vehicle pulling, and wheel vibration or wobble.
