Here is a link to John Deere's on line parts catalog for the 40 series tractors. It covers all the models, so be sure you are looking at pages that include the U in model covered. Look at pages 82-83 to start.

There is a short rubber seal under the
big nut. As you tighten the nut it
forces the sides out to seal. Try
tightening it up and if that fails order
a new one from Deere. Less than $10. I
would replace them all on the return
line.

Thanks, this makes sense, I found a self fabricated cork seal behind there that would have been as good as a screen door in a blizzard. Ill try to track down a rubber seal from parts list that was posted above. Thanks again
