The Dorman BJ81056PR front upper ball joint is a direct-fit replacement for 2011-2026 Ram 3500, 2500, 4000 & 2003-2010 Dodge Ram 3500, Ram 1500, Ram 2500, Ram 4000. It forms the pivot between the control arm and steering knuckle, carrying vehicle weight while letting the suspension travel and the wheel steer. Excess ball joint play leads to clunks, vague steering and uneven tire wear, so a worn joint should be replaced before it separates. It is built from steel.
