I am going to top off the hypoid oil in the rear diff . I have had a slow leak for a while and it's time to check it out. Looked for photo on the forum for location. Could not find one. Just want to make sure I remove the right plug. Is it on the driver's side by the output axle, about 2 inches up from the bottom of the diff? I don't want to manhandle the wrong plug. It looks so clean for a fill plug, just not sure and I could not locate any other fill plugs.

The leak is coming from somewhere on top of the diff, but I can't see it. It's so slow that I'll just fill it until it gets bad, hopefully another 100k miles.
