General Maintenance & Repairs - GM 10 Bolt pumpkin is always wet...?

If I clean the undercarriage and my rear end, a few thousand miles later my entire pumpkin is wet from gear oil, not bad but wet none the less, where is the common leaking area for these? Front oil seal?
I already changed the fluid and resealed the auburn alu, cover with permatex as specified so I don't think its the cover.

It is the pinion seal.
I found it helps, when replacing the seal, to clean everything real good and use red loctite around the OD of the seal, grease in the ID. And when you put the yoke on use a good sealer like ARP thread sealer (http://static.summitracing.com/global/images/prod/large/arp-100-9904.jpg) on the splines. And more red loctite on the pinion nut threads.

My 10 bolt leaked like crazy. My Moser 12 bolt was dry for about a year and now leaks more than I wish. :(

If it is the pinion seal you should see where it is slinging onto the underbody in front of the rear end. There should be like a circle or arc of rear end fluid above where the yolk goes into the front end. A 'spinning' leak. You also may smell rear end fluid on your exhaust.
