The control arm locates the front right lower wheel and pivots on its ball joint as the suspension moves and the wheel steers. Signs the original may need replacing include clunking from the front suspension over bumps, uneven front tire wear, and loose or wandering steering. If a worn control arm or ball joint is the cause, this assembly replaces it.
