Transfer case bearing KIT (MFA RDM)

Common symptoms of failing MFA RDM bearings include a distinct whining or grinding noise coming from the drivetrain, especially during acceleration or deceleration. You might also feel unusual vibrations or a shuddering sensation through the floorboard as the bearings lose their ability to stabilize the shafts.

Yes, the MFA RDM system is typically found in Mercedes-Benz transverse-engine models equipped with 4MATIC, such as the A-Class, B-Class, CLA, and GLA. This kit is specifically designed to support the internal shafts of that specific rear drive module/transfer case setup.

Replacing transfer case bearings is a complex task that requires specialized tools like a hydraulic press and bearing pullers. Because precise torque balancing and shaft alignment are critical, we highly recommend having this kit installed by a professional mechanic or transmission specialist.

Replacing the bearings is a much more cost-effective solution than buying a complete new MFA RDM unit. By catching the wear early and using this high-quality bearing kit, you prevent the shafts from damaging the transfer case housing, which would lead to a far more expensive repair.

Absolutely. These bearings provide the necessary support for the internal shafts to rotate smoothly. When bearings are worn, shaft play occurs, which disrupts the balance and efficient transmission of torque to the wheels, often leading to power loss or jerky movement.
