Removal

NOTICE: When replacing the RDU clutch, the ATC coil and yoke are a matched set and must be replaced also.

NOTICE: When replacing the RDU clutch, the 4X4 control module will need to be reconfigured with the new Active Torque Coupling (ATC) bar code information. If the new bar code information does not match the existing 4X4 control module information, driveline damage or driveability concerns can occur.
