Transfer Case Encoder Motor (Actuator)

Happy Hummer

Having "Service Stabil Trac" warnings coming up each day?

06-10 Transfer Case Motor Encoder (Actuator) part no. 89059551,(89059688),19300596. Also seal: 19209788

TCCM is usually not the culprit in this case and is 2nd to be replaced if the encoder does not work.

The encoder is located at the rear of the tranx case and will need a gasket from what I've been able to ascertain.

The price is typically $200
