1987 D6H my hyd oil was low cant find any external leakes is it possible for it to leak into the bell housing it is diff steer its a 5HF
Is the belly pan full of dirt? It can hold a lot of oil before you notice a leak. Not sure about the bell housing.
belly pan is fairly clean took floor board out and cant see any leaks
Someone should be along shortly that will have an idea.
yes it is possible also the steer motor is a possible source as well But have you checked your compartment levels to confirm?
