It is built with a steel stamped arm, rubber bushings, and a press-in ball joint that is already installed, helping simplify replacement on Ford Escape, Mazda Tribute, and Mercury Mariner rear suspension service. The assembly is pre-greased and supplied with mounting hardware, making it a practical choice when restoring worn rear suspension components. Dorman 522-320 is intended to help return predictable suspension response, directional stability, and a smoother ride after wear-related failure.\u003c\/p\u003e\u003cp\u003eThis part cross-references MOOG Chassis Products (e.g., RK621455) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Repair Symptoms\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRear suspension clunking or knocking over bumps\u003c\/li\u003e\n\u003cli\u003eUneven tire wear caused by worn rear control arm components\u003c\/li\u003e\n\u003cli\u003eLoose or unstable rear-end handling\u003c\/li\u003e\n\u003cli\u003eExcessive suspension play from deteriorated bushings or ball joint wear\u003c\/li\u003e\n\u003cli\u003eAlignment issues after rear suspension component wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify vehicle fitment by year, make, model, and rear right lower position before installation. Inspect adjacent suspension components, fasteners, and mounting points for wear or damage before reassembly. Because the ball joint is installed and the assembly uses a press-in design, replacement should follow the correct service procedure for the vehicle application. After installation, a professional alignment check is recommended whenever rear suspension geometry has been disturbed.\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 support proper ride quality, stability, and suspension behavior.
