Get under the truck and spray the tail shaft/seal area with brake cleaner. Then watch closely to see where the leak is coming from. Is the tail shaft possibly cracked where the seal presses in? I always put a skim of RTV around the outside of the seal before I press it in the tail shaft. Good luck.
