My left Axle is leaking fluid for the second time. It was just fixed under warranty a couple months ago. Question...Before getting it fixed again I want to check the rear end level but am not sure where the oil should be. Champion says when changing fluid not to put in more than one quart and I'm told that this won't take it up enough to drip out when the plug is removed. But..how much below this port should the oil be? Champion says not to fill above that hole, but that's really impossible. The leak is very small but I don't want to run low on oil before I can take it in.
