As a steering tie rod end, this inner joint lets the linkage pivot as the suspension travels and the wheels turn. Signs it may need replacing include steering play or wander, a clunk while turning, and uneven tire wear. These symptoms can have other causes, so diagnose the problem before replacing parts, and have the wheel alignment checked after installation.
