I have always regularly checked the oil levels in the Detroit couplings in my Shadow 2 at least once a year and corrected the oil levels when required. They have never needed more than a few mls. of oil.
When checked recently, there was very little oil in either of the couplings and when I removed the differential filler plug, the diff oil level was higher than it should be as oil poured out. The level was correct last time it was checked. There are no oil leaks from the drive shafts or diff.
My question is why has the oil decided to migrate into the diff after so many years and what is the likely cause? The only suggestion I have is that perhaps the diff. breather in the top of the diff housing has become blocked and a vacuum is drawing the oil through the centre bores of the drive shafts.
Does this sound likely? Any thoughts on the likely cause gratefully received.
