I don't understand the need for grease to "flow" inside the Alpine steering box. I have had them apart and am convinced, especially during a rebuild, that if the parts are greased as they are assembled, there is no need for grease flow anymore than there is in a wheel bearing. There is a tendency for grease to accumulate in the steering column tube, maybe the thin grease oozes back into the steering box, while chassis grease stays.
