Keep the rear suspension located and controlled with the Beck/Arnley Suspension Control Arm 102-7974, a rear upper center control arm that drops in as a direct-fit replacement for the 2011-2017 BMW X3 and 2015-2018 BMW X4 (see the Buyer's Guide tab for engine-level fitment). A control arm connects the suspension to the chassis, helping position the wheel and manage suspension movement while the bushings absorb road vibration.
Signs this part may need replacing include clunking on acceleration, deceleration, or over uneven pavement, a wandering feel, and uneven tire wear. If a worn control arm or its bushings are the cause, replacing this unit addresses it; diagnose the cause before ordering, and it is best practice to inspect both sides.
