I pulled off the transfer case actuator and motor, ready to replace the gear to cure my trifecta. Couldn't get the d*** cover off the actuator gear so I instead did the 180 degree turn. Fixed the trifecta! Now have the new gear in the parts box, ready to replace when it happens again. I could look through the motor port and see where the gear was worn. Lights off, drove to KY for the horse races, no recurrence.
