Our left-rear unit has had a small leak for a while now, but the entire unit has had fluid on it. Our friend who is a tractor mechanic said the fitting on top of that jack, that has two hoses into it has an O-ring where it attaches to the top of the unit, and that is probably what is leaking. He said it is a quick fix, just need an O-ring. If there is no oil on the outside of the unit, then it is the lower seal.
