What kind of oil are you running??

Interesting idea about the IR gun... about a month ago i refilled it with a generic 80w-90 after I noticed the oil was bad. Had a bad carreir bearing so I had it replaced today. This time I got some (i think these are the specs) 85w-140 valvoline synthetic blend. Meets the GL-5 spec, and it says it's suitable for all hypoid diffs.
Took 'er for a spin and figured i'd just check to see if the seal took, which it did. Never checked the temp of it after a drive, so I placed my hand on it and, damn, it was hot. Wondering if it's normal or if something was put back together wrong.
