N182201530 - Service Update. Certain vehicles, equipped with AWD (RPO F46), may have a condition in which the front portion of the propeller shaft slips out of the Power Transfer Unit (PTU) and drags on the roadway. The driver may hear a dragging noise from beneath the vehicle, but there will be no driver information center/cluster warning messages. Dealers are to inspect, and if necessary, reseat the prop shaft to the PTU and rear differential carrier assembly.
