Hello everyone! I recently just got access to a car lift of my own and I decided to lift my 2006 Range Rover into the air and take a look underneath. I discovered that everything looks to be in place and is dry except there seems to be a very slow but apparent leak coming from the rear diff. Ive done a little bit of research but can not seem to find what is going on. I have attached photos of the leak below. any help would be amazing as my solution for now is to just top it off every couple thousand miles.
