Mevotech Supreme Suspension Ball Joint P/N:MS60509
Keep the front suspension tight and the steering precise with the Mevotech Supreme Suspension Ball Joint MS10577, a front lower ball joint engineered in-house with application-specific upgrades for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. It fits a wide range of xDrive BMWs, including the 2014-2019 BMW 640i xDrive Gran Coupe, 2014-2018 BMW 640i xDrive and 2012-2018 BMW 650i xDrive — see the Buyer's Guide tab for the full list.
A ball joint pivots the lower control arm against the steering knuckle so the suspension can travel while the wheel steers. If a worn joint is behind clunking over bumps, loose or wandering steering, or uneven tire wear, replacing it addresses the cause.
