So as the title states, I think I needed to change my diff oil, or i suppose lack there of.... the pictures you see of the disassembled diff is my center diff. Iam putting oil in all of them front and center are done, just need to do rear... the lack of fluid you see in them in the pictures is EXACTLY how they were when I opened them. This is my first time replacing the fluid since i got it brand new for christmas...

Also is it normal for the front diff to have grease around it, i think its to lubricate where the front center dogbone and front diff meet... Iadded some 5000wt diff oil to it in case i knocked off some grease.....
