JUst pull the thing apart and take a look. Its only 10 12mm bolts, slide the axle stubs out, and pull apart. If you dont know what your looking at as far as the LSD goes, post some pics up, or I even think I have a few pics of a visous/clutch, and even torsen LSDs for comparison.

This isn't a fail proof test but it's worth a shot:
On the lower drain plug on the S4 clutch type, there is a tag that says something like "rear diff clutch pack requires a friction modifier". The S5 viscous type does not have this tag.
If you have the tag, it should be an S4.
If you don't have the tag, it could be an S5 or an S4 with a tag missing. Good luck!
