How to replace the 4WD Actuator Encoder Motor on Chevrolet Colorado?

Begin replacement of the Transfer Case Encoder Motor by lifting and supporting the vehicle properly. Disconnect the electrical connector and the vent hose before removing the encoder motor. You must remove encoder motor mounting bolts to extract the encoder motor from its slot together with its O-ring seal which must be discarded. Install the new encoder motor after you make sure the transfer case actuator shaft rests in neutral but avoid using the encoder motor for this maneuver. Apply a thin layer of clean transfer case fluid to the new O-ring before inserting it into the transfer case while making sure the encoder motor maintains a flat position against the seal. Mount the encoder motor into place adjacent to the actuator shaft while installing the mounting bolts together with the heated oxygen sensor bracket using 22 Nm (16 lb ft) torque. Complete the process by attaching the vent hose along with the electrical connector to the encoder motor and then lower the vehicle.
