Keep the front suspension pivoting smoothly and the steering connected with the Beck/Arnley Front Lower Suspension Ball Joint 101-4105. This ball joint forms the pivoting link between the front lower control arm and the steering knuckle, supporting suspension load while allowing the wheel to move up and down and turn. It's engineered as a direct-fit replacement for foreign-nameplate applications, including the 2005-2006 Saab 9-2X, 2003-2006 Subaru Baja, 2016-2024 Subaru Crosstrek, 1998-2025 Subaru Forester, 1993-2016 Subaru Impreza, 1990-2024 Subaru Legacy, 2000-2025 Subaru Outback, 2013-2025 Subaru WRX, 2013-2021 Subaru WRX STI, 1988-1991 Subaru XT, and 2013-2015 Subaru XV Crosstrek — see the Buyer's Guide tab for engine-level details.
Worn ball joints can show up as clunking or popping over bumps, wandering steering, or uneven front tire wear. If a failed lower ball joint is the cause, this replaces it. Because ball joints wear as a pair, consider replacing the opposite side at the same time for balanced handling.

What are signs my ball joint may need replacing?
Clunking or popping over bumps, wandering or loose steering, and uneven front tire wear can indicate a worn ball joint. Diagnose the cause before replacing.
