What is used to control the direction of the front wheels?

The direction of the front wheels in a vehicle is controlled by the steering system, primarily through the steering wheel, steering column, and steering mechanism. When the driver turns the steering wheel, it activates the steering linkage, which pivots the front wheels in the desired direction. Common types of steering systems include rack-and-pinion and recirculating ball systems. These systems translate the driver's input into movement, allowing for precise control of the vehicle's direction.
