If your talking about the extra shaft behind the trans and before the torque tube in the 1936 1.5 ton trucks, what do they call that the mid-shaft? I tried to look that up in the on line books here and couldn't find the amount of oil or what kind of oil to use either. anybody know? I read they use to fill it with that zerk fitting on top of the rear of the trans and the used pour oil at the factory. i am sure somebody here knows what to use and how much should be put in. Because i need to know too.
