The one in my 69 Ford Cobra has leaked a little from day one. I have tried everything but leaving the grease out. Just a drop or so and never much but I just gave up and quit trying to stop it. I have never found it low on grease so I think the wind makes it look like more than is seeping out. If I let it set in the garage for a few weeks there will be one drop on the floor. I even checked to make sure I had the locker type grease in it. I think the 9" rear is an off spring of the FE motor.
