2010 Jeep Commander Pinion Seal leaks

Hey fellas! My sweetie drives an '10 Commander 3.7 V6. The rear pinion seal is starting to leak and I'd like to save her a few bucks. I've changed older Mopar 8.75 pinion seals before. This can't be any different, can it?
I crawled underneath and other than the driveshaft looking different it seems like a easy deal. Anyone on here ever do one? What do you guys think?
