Are your input and output seals good?

I got a rear tandem cut-off for my International in trade from a guy. He drove the truck in I believe, but when I got it I ended up having to rebuild the inter-axle differential because the input seal was bad and I figure it got rain in it over the years as it sat. I ended up having to put a sleeve on the input yolk.

I second Grigg on "having words" with them. They had better find it or give you a majority of your money back.
