Front upper left control arm with integrated ball joint designed for 1989–1997 Ford and Mercury vehicles. This direct-fit suspension arm restores proper wheel alignment and steering geometry, securing the front wheel assembly while absorbing road forces and maintaining tire contact. Built from stamped steel with a durable coating and a pre-installed sealed ball joint, it delivers long-lasting reliability and simplified installation for restoration or routine suspension repairs. Ideal for replacing worn or damaged arms to eliminate play, reduce vibration, and improve handling.
