Hi. On the top of the back half of the differential is a small hole with a cotter pin thru it and slightly flared inside of it to retain it. Is it just a vent hole and the cotter pin is to keep the oil from splashing out?

Thanks Ralph. I'm getting your weather today. Not supposed to stop snowing here until tomorrow night!

The less said about this weather, the better! winking smiley

I suspect the theory behind the cotter pin is that it might "jiggle" enough to keep the vent clear. Of course, as Rocky used to say to Bullwinkle; "But that trick never works!"

For what it's worth, I recently excavated mine. It took most of a day to discover that there is a plate on the deck in the boot just forward of the masonite closing piece behind the rear seat, that allows access to the hole and pin. With the vent clear, the pinion seal leak went from massive to just about nothing. I no longer have to carry a drip pan in the boot.

Tom, it's so nice to have "independent confirmation" of what I've been saying -- and practicing -- for years! Thank you!
