Describe a "tie rod".

A tie rod serves as a crucial connecting link between the steering mechanism and the front wheels of a vehicle. Its primary function is to allow the wheels to pivot and turn in response to the driver’s input via the steering wheel. By linking the steering gear to the steering knuckle at each front wheel, tie rods help ensure that when the steering wheel is turned, the angle of the wheels changes accordingly, facilitating vehicle maneuverability. This is essential for proper handling and control of the vehicle, allowing for smooth and safe navigation on the road. Tie rods must be in good condition to maintain proper alignment and prevent steering issues.
