The lateral arm helps locate the rear wheel and maintain suspension geometry, while the integrated ball joint allows controlled articulation. Signs this part may need replacing include clunking or knocking from the rear, uneven tire wear, and loose or wandering handling. If a worn lateral arm or ball joint is the cause, this assembly replaces it. For even, balanced results, consider replacing the matching side as a pair.
