Front diff leaking antifreeze?

I tried searching this but I couldn't find anything.

I was under my 1995 GMC Jimmy 4X4 yesterday fixing the oil filter lines when I noticed I had an antifrezze leak. The antifreeze is mixed with oil and it is at the bottom of the front diff where it bolts together (middleish). First thing I did is to look above it on the engine to see if the leak is coming from there and dripping on the diff. I can't see anything leaking up there. The top of the diff is not even wet. I just bought the Jimmy about 2 months ago and I am not too familiar with it. Am I missing something? Any help is greatly appreciated.

It's probably either the intake gasket or the waterpump weep hole. Your best bet is to pressure wash the engine then you can see better where it may be coming from. The front diff itself doesn't have antifreeze running through it so you need to pressure wash it so you can get a better idea.
