The term 'Steering System Components' refers to the parts of a vehicle's steering system, which is responsible for controlling the direction of the vehicle. These components include pinions (7 letters), tierods (7 letters), and frontaxles (10 letters). Pinions are small gears that are used to transfer rotational motion from one shaft to another. Tierods are rods that connect the steering knuckle to the steering arm, allowing the driver to control the direction of the vehicle. Frontaxles are the main components of the steering system, connecting the wheels to the steering gearbox and allowing the driver to turn the wheels.
