I share Parazine's doubt that anything was changed by Austin to retain the oil in later axles. That's fundamentally why they leak, because the sealing structure is appropriate for retention of grease, not oil.
I also share Simon's experience, stripped a '31 axle last autumn which was grease filled, and it would take more than a slosh of diesel to remove the vast quantities of the stuff packed into every nook and cranny. It's arguably not doing any harm, depends on your plans I guess. If the axle is running quietly it may be better left alone. If rebuilding with an expensive new CWP then you know the answer...
