Rear Diff. felt warm. Is this OK?

I removed my transfer case spacers and took the jeep for a test drive looking for vibes. When i returned (5 to 8 min) drive i got under the jeep to check what kind of rearend it has. When i touched the diff. it felt very warm to the touch. I have never noticed this before on other vehicles i have owned. Should i be worried? Should i check if it needs fluid added?

check the fluids b/c they may need to be changed. friction= heat, it is not really uncommon for the diff to be warm after use.

x2 Being warm is normal. Too hot to touch though is a whole different can of worms.

synthetic is the way to go in your dif's. I run synthetic in my front and rear dif's.,transmission,and transfer case. I think it helps out and helps slightly with fuel mileage.
