I have a leaking rear differential. It is definitely coming out of the rear cover and it may be coming out of the front seal also. It's a mess so I can't tell about the front seal. It is also all over the radiator. It shows only a couple of drops on the floor, but what a mess underneath. I know it's a Ford, but I can't remember if it's a 6.5" or a 7.5". Does anybody have any more information about it? Thx Rick
