Regardless of the type of steering system in your vehicle, you use inner and outer tie rods. As an important part of your vehicle’s steering and suspension system, tie rods act as the link between your vehicle’s steering system and the steering arm, which is attached to the steering wheel. When you turn the steering wheel, the steering arm moves the front wheels through the steering system. The inner and outer tie rods connect to the steering arm in order to move the wheels of your vehicle. In the common rack-and-pinion steering system, the inner tie rods connect to the steering rack while the outer tie rods connect to the steering arms. The tie rods make steering and turning possible by moving your wheels in the desired direction. Without properly functioning tie rods, the steering mechanism would no longer operate as intended. Because inner and outer tie rods play such a significant role, replacing tie rods as necessary is important for overall vehicle maintenance.
