Beck/Arnley Suspension Control Arm and Ball Joint Assembly P/N:102-8289
Tighten up steering and ride control with the Beck/Arnley Control Arm with Ball Joint 102-8368, a front left lower BMW X3 control arm that drops in as a direct replacement on the 2018-2024 BMW X3 and 2019-2024 BMW X4. Built to match OE form, fit and function, it locates the wheel and lets the suspension travel while the integrated ball joint carries the steering pivot.
A worn arm or bushing can cause clunks over bumps, loose steering, and uneven tire wear; if the original BMW X3 lower control arm is the cause, this assembly replaces it. Diagnose the underlying issue before installing.
