Problem with that ^ theory is that there is a rubber boot built into the hub cover cap that expands to relieve any pressure. On hot runs I see those boots bulged outward and cold they are pulled inward.
Well, we all seem to have different thoughts on this subject. It works for some and not for others. One thing for certain, when the pressure builds in the hub the grease is going to take the path of least resistance. In my case it was the seals into the drums, possibly because my coach had between 25 and 30 thousand miles on the seals.
