- Fits: 2013-2019 BMW 650i xDrive Gran Coupe and other vehicles

A clunk over bumps, uneven front tire wear or loose steering can mean the arm or its ball joint is worn, though other suspension parts produce similar symptoms, so find the cause before replacing it. With the engine off, start by looking for a torn ball joint boot, leaking grease, or cracks and rust on the arm; a shop can test joint play. Both front sides are normally replaced together. This listing is one arm for the front left, and the front right is a separate part.
