What is the primary function of a tie rod in a steering system?

The primary function of a tie rod in a steering system is to connect the steering gear to the wheels. This connection allows the steering gear's movements to be transmitted directly to the wheels, ensuring that when the driver turns the steering wheel, the wheels respond accordingly. Tie rods play a crucial role in enabling the vehicle to turn and navigate as intended, effectively linking the steering mechanism with the wheel assembly.

By facilitating this connection, tie rods help in the overall maneuverability of the vehicle. They are integral components that also assist in maintaining proper alignment and stability of the steering system, but their fundamental role remains in connecting the steering gear to the wheels, which is vital for the vehicle's control and responsiveness.
