Setup, Compatibility & Care
Before beginning installation, verify the specific part compatibility using your BMW's VIN or the OEM references listed: 7516323, 7516324, 7525256, 7531620, 7578306, 7578307, 7625974, or 8647877. The repair process involves draining transmission fluid, removing the driveshaft or differential housing, and carefully seating the new components. It is highly recommended to use a torque wrench to ensure all fasteners are tightened to factory-specified levels. After installation, fill the system with the manufacturer-recommended lubricant and inspect for leaks during the first few miles of operation.
