A tie rod is the connecting link between the steering gear and the wheel. When you turn the wheel, the steering rack pushes and pulls the tie rods, which swing the front wheels left and right. Each has an inner and outer joint that pivot as the suspension moves, and like any joint under constant load, they eventually develop wear and play.
A worn tie rod lets the wheel wander slightly on its own, which shows up as loose or vague steering, a clunk over bumps, and tires that scrub and wear unevenly. Because the tie rods set the wheel's toe angle, replacing one almost always calls for an alignment afterward. At New Concept we check each joint for play, confirm which one is worn, and plan the alignment so the car steers tight and tracks straight.
