Replaced Speedo Cable now NP205 seems to be leaking a bit from connection?

[DuvallDawg]

I replaced my speedo cable, went for a good long drive yesterday and noticed some fluid under truck (very small amount) on inspection, looks like leaking from connection point of speedo cable on transfer case. Everything seems to be nice and tight, not sure if I missed a gasket or washer or something?

Thanks guys!

O ring? Slides over end of cable that clamps into T-case.
