hello all. I noticed there was some oil dripping from under the diff. assuming the pinion seal I delivered the big dog to my indie. I just got a calll earlier today and went out to look at it. it appears that the diff housing has pinholes all over the area between the pinion seal and the area where the axle tubes attach.

He thinks it has rusted out. The rest of it looks pretty free of rust.

Anybody had a diff housing rust out? (sounds preposterous!)
