UE Diffs, grease?

[neweuser]

I am putting together the UE 8 Spyders. I have my oils in, but not sure if Multipurpose grease will work on the outside for the pinions and what not? It's from the Auto Store for bearings and other lubable (if that's a word) parts. It's #2 Grade Lithium grease (multi purpose). Will this be ok? Thanks as usual guys! Almost done!
