Suzuki Samurai Transmission Output Seal.
Is your Samurai marking its territory?
There are a few places the Samurai likes to leak and the transmission output seal is one of them.
This is a fairly simple in the driveway fix, with the proper tools, just remove the intermediate driveshaft, using a good screw driver or a seal removal tool you can pop
the old one out. Then with a small hammer and a large socket gently drive the new one in.
If you find that you are going through alot of these seals then the issue is either with your intermediate driveshaft or the tailshaft busing.
