Are you following the diff fill procedure exactly or is it getting a bit too much fluid?
On some years the plug in the diff was a bit higher than the seals in the axles and filling her all the way up would cause the seals to weep slightly.
I bought the truck used and noticed the leaky seals at 110,000 miles. When I replaced them I filled to the bottom of the fill plug.
I don't have the exact fill procedure. Do you have a link to it? I'm finding references saying to fill with 4L of 75W90 and to be 1/4" below the fill hole with a +/- of 1/4". So basically that is saying you can fill between 1/2" below or right up to the hole.
If filling right up to the hole causes problems for the seals it seems odd the fill procedure would allow for it.

They kept changing it over the years - mine is like 1/2" below the filler (I think - have to recheck). Do you have the original owners manual? I think it will be in there.
If not, you might check out The Turbo Diesel Registry and ask there.
Good luck!
