I have a 1972 -40 with a 1979 4 speed tranny. I have had a drip under the e-brake even after I had the tranny re-done with new gaskets etc... I have read quite a few threads here on Mud about this issue but I am not still not clear if I have a Transfer Case Seal issue or a Spline Leak issue. I have included a photo below. You can see the oil coming out at what appears to be the spline. Am I possibly missing a washer or something else? I did read where some folks use a silicone sealant around the spline to stop a leak, I just want to be sure that is the issue and not th Transfer Case seal. Thanks for the help.
