I don't know why so many people want to find alternatives to an already synthetic fluid that is made for the transfer case it is intended to go in and not a universal fluid that "meets" a spec that hasn't even been released by the manufacturer.
I would tend to agree. You cannot assume that all Factory OEM Fluids or Parts are still much higher in price just because they are made for this or that specific vehicle or part.
