The aluminum control arm uses rubber bushings and an installed ball joint to match the original suspension layout, helping maintain proper wheel control and suspension response. Dorman part number 522-871 is evaluated to support consistent ride behavior and stable steering feel in everyday driving.\u003c\/p\u003e\u003cp\u003eThis part cross-references Beck\/Arnley 102-7678 and Delphi TC2833 for the same application. It is a practical OE-style replacement for BMW 535i GT, 550i GT, and 7 Series models where the original control arm and ball joint assembly has worn or lost precision.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFront-end looseness or reduced steering precision\u003c\/li\u003e\n\u003cli\u003eClunking or knocking from a worn lower control arm\u003c\/li\u003e\n\u003cli\u003eUneven tire wear caused by suspension wear\u003c\/li\u003e\n\u003cli\u003eDirectional instability during braking or lane changes\u003c\/li\u003e\n\u003cli\u003eBall joint or bushing wear in the front suspension\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the front left lower rearward position before installation. This assembly uses a press-in ball joint design and includes mounting hardware, so proper suspension service tools and torque procedures are important. Because the control arm is not adjustable, final alignment should be performed after installation to confirm correct suspension geometry.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDorman evaluates this control arm and ball joint assembly through an industry-focused validation process to help deliver consistent ride quality, directional stability, and predictable suspension dynamics.
