It's recommended to change the differential fluid every 30,000 miles. I'm coming up on that soon and after looking at it I'm wondering how to get the new fluid in better than squirting it in with an oil can. The filler hole is horizontal with the ground and no way to get a funnel there and pour it in.
I'll use the squirt can unless someone can give me a better idea.
