Tie rods similar to small ball joints and allow up and down movement and rotation of the steering components. A tie rod can both turn and pivot which maintains the connection between steering and wheels as the suspension moves. Tie rods normally come in pairs, an inner and an outer. The inner tie rod will be closer to the center of the vehicle and the outer tie rod is nearer the wheel. They normally use threads to connect the inner and outer tie rods.
