What is the role of tie rods in a vehicle's steering system?

Tie rods play a crucial role in a vehicle's steering system by connecting the steering gear to the steering knuckles. This connection allows for the transfer of movement from the steering wheel to the wheels, enabling the driver to steer the vehicle effectively. When the driver turns the steering wheel, the steering gear moves the tie rods, which in turn move the steering knuckles and thus the wheels. This action is essential for ensuring precise alignment and control of the vehicle as it navigates turns or changes direction.

The tie rods also help maintain proper alignment of the wheels, impacting handling and overall vehicle stability. Their design and functionality are vital for responsive steering and safe maneuverability. Understanding the tie rod's function is essential for diagnosing steering issues and performing maintenance effectively.
