Perhaps I spoke too soon. The problem persisted even after a new passenger side axle was installed (This did cure the 'noise on acceleration' problem that I had, however). The dealership is now stumped. They checked the data streams from all sensors, tried swapping out the passenger side sensor, counted all the teeth on all the sensor rings, all without success. It currently looks like I'll be switching off the TC on each startup, unless one of you has a better idea.
