Help keep your truck's front end tight and predictable with the Mevotech TTX front upper 2017-2020 Ford F-150 ball joint, part number TXMS40557. It is a direct-fit replacement for the 2017-2020 Ford F-150. See the Buyer's Guide tab for engine-specific details.
Mevotech engineers its TTX line for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. Its Labor Saver designs, tools and hardware are intended to make installation faster and easier.
Mevotech puts the design through extensive in-house and third-party durability testing. In the front upper position, the ball joint links the upper control arm to the steering knuckle. This lets the wheel pivot as you steer and move with the suspension. Signs a worn ball joint may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. Inspect the front suspension to confirm the cause before replacing parts.
