I had no leak from the rear end. I changed my rear end fluid about 6 months ago. Now I have a small blop of fluid on the floor each week. It is not comming from the drain/fill plug. Originally I thought maybe I overfilled, and it was comming out an overflow, but I think it has been going on too long. I need to pop the plug again to see where the level is now. Has anyone seen this before?
