Detailed Description

The transfer case motor is a critical component in the AWD system, where it helps synchronize front and rear axle rotation through the transfer case assembly. When the motor wears or fails, the transfer case may not shift or regulate torque correctly, which can affect drivability and increase stress on related drivetrain components. Rein TDA0012 is built to OE specifications to restore proper operation on Mercedes-Benz G-Class models, including the Mercedes-Benz G550, G550 4x4, G63 AMG, G65 AMG, G55 AMG, and G500. For service work on these vehicles, Rein also recommends replacing the transfer case fluid with FLDF002 when the motor is replaced.
