I changed out my gearing about a month ago. Today, I had my truck up on a lift to chain my oil and I noticed that there is fresh oil on the bottom of my transfer case.

It doesn't appear to be coming from the drain or fill ports, or the rear driveshaft.

Its either coming from the front driveshaft output or the split case.

How common is this.
