Mercedes G500's have a similar problem - an expensive actuator is disabled by an inexpensive gear. On those cars, the actuator cycles thru every time you start the car, so even if you never use AWD, the part wears out eventually. On the Mercedes the ignition won't work at all if the unit does not cycle correctly, meaning sometimes you have to try starting the car a number of times before the unit orients correctly. There are a few remanufacturers that will do the units fairly cheaply, and some people have reported success in finding the $20 gear instead of the $700 unit. Might be worth looking into as far as the X3 goes.
