Keep the front upper suspension tight and steering responsive with the MOOG Chassis / QuickSteer Suspension Ball Joint K500138. This front upper ball joint drops in as a direct-fit replacement for the 2008-2010 Dodge Ram 4500 and 5500, the 2011-2023 Ram 4500 and 5500, the 2008-2009 Sterling Truck Bullet 45, and the 2008 Sterling Truck Bullet 55 — see the Buyer's Guide tab for engine-level details. A ball joint pivots the steering knuckle while carrying suspension loads; worn units show up as play, clunks over bumps or when turning, and loose or wandering steering, so if a failed joint is the cause, this replaces it.
Gusher bearing: Metal-to-metal design adds strength and lets grease flow through the bearing surface to reduce friction.
Greaseable socket: A grease fitting lets new lubricant flush out contaminants and debris.
Heat-treated ball stud: Treated to match or exceed OE requirements to resist premature failure and improve fatigue strength.
Belleville preload washer & pressed-in cover plate: Help keep the bearing package tight as it wears and seal out debris.
Coated for corrosion resistance and machined to precision tolerances for OE fit and function. Replacement helps restore vehicle handling.
