Hello, in one threat before I ask about the seals in the housing that sits on the differential gear - see photo. My question is in which order does the seals - the felt ring and the oil seal sit in the housing? On the bottom ( to the propeller shaft) the felt ring and then the oil seal ( to the differntial gear) or other way around? For remember I have a 3/4 ton truck build 1953 with a 4 speed gear. Ask Wolfgang
