Can any one tell me where this leak is coming from? It isnt coming from the plug or the cover?? any ideas would be appreciated.

Check to see if its damp/moist at the front of the pumpkin, right where the driveshaft connects. If so, its a bad pinion seal.

another angle

pinion seal is dry??

Wouldn't be the first time I seen that. The axle tubes are pressed in the center then plug welded in those holes. My guess is there is a pinhole in one of the welds letting lube go thru. Brake clean the crap out JB weld the holes, just a smear works. You can see lube creeping out between the tube and center too. Is the diff vent plugged letting pressure build up in there?

Clean the hole and weld the tube shut

wow, that seems like a ridiculous design from chrysler? do I need jb weld the holes and around where the tube meets the pumpkin? Do I need to worry about this falling apart? I couldnt see where the diff vent is located, where should I look?

Thanks for the help on this once guys

It's been a common practice for most all makers to put their diffs together like that. Been doing it for decades and are still doing it. It won't fall apart, just be a leaking nuisance.

The vent is on the drivers side tube with a hose on it that should be clipped to the frame someplace.

I'd clean it up like was mentioned, and keep a good eye on that brake line.

Yes, i completely forgot about that!
