The steering knuckle assembly or the spindle knuckle assembly, is where the suspension, the steering system, and the front wheels of the vehicle meet. This allows us to control the wheels and turn them in different directions while driving. The steering knuckle is an essential component in a vehicle since it ensures that the crucial parts of the vehicle that help in operating the wheel are intact. 

The steering knuckles in a vehicle allow the wheels to move vertically when the suspension reacts to road disturbances and horizontally as a response to the steering input. Although steering knuckles and spindles are often long-lasting components, if the steering knuckle assembly on your car is damaged and needs to be replaced, you can find a used steering knuckle right here.
