'89 marathon rearend


New Member
Hey everyone, I was going to service the differential on the cart today. it is a 1989 Marathon. I couldn't find a drain plug on the housing, I searched the archives and it looks like it should be on the lower portion of the pan. the only thing I see is a vent on the aft side of the differential but couldn't find a drain/fill plug. any ideas????? also does anyone know if there is a service manual for this year and model posted some where on the boards. thanks in advance.
