Thanks for the link to that TSB, I did some more digging and created jpgs of the FULL TSB and saved them to my computer.
That TSB prompted me to decide to get the LMC electric (replacement for a thermostatic) actuator & corresponding actuator harness upgrade.
Between the front diff, and the rear, what is the logic for these actuators?
Is it because of the theoretical(?) increase in mileage from a more conventional posi - based on the merits of both wheels receiving power full time equating to lower mileage??
