xfer case seals shot?

[sparkyy192]

Was down greasing the prop shaft when I noticed this mess.

100k on the vehicle, a lot of hard offroad miles. It looks like the seals at both ends are done, is there a writeup on pulling the xfer case and replacing all the seals? I found one for the 3rd gens, but can't seem to find one for ours.

I would clean it all off and inspect again in 50-100 mines to try to pinpoint the source of the leak.

I once changed the rear seal for a leak only for it to come back immediately, as the source was the O ring sealing the cover where the speedo sensor would be on an earlier model before they used the ABS sensors exclusively. The wind blowing the oil made it look like the rear seal was the culprit.
