On the differential around the middle to top of it there will be a plug. Usually these are squared instead of the normal hex bolt head. Just remove the plug and add your fluid. Add fluid until it comes out the fill hole and then put plug back in. I would reccomend cleaning the differential so you can check later on where the leak is coming from. It may just be a gasket from the case or even from the plug itself.
