Leak coming from where driveshaft enters rear differential

Is this common. I was bouncing around on some rocks...but don't think I hit the driveshaft. Is there anything specific that would have caused this?

Driveline vibes will cause this. I saw from another one of your posts that you have a 2" lift, BL and MML. Make sure your driveline angles are correct.

Since you also have a Dana 44 and a 5-speed, like myself, even a 2" lift can cause vibes. If you go out and measure your drive shaft, you'll find it's only about 18 inches from the yoke to the tailshaft housing. A shaft this short will create ungraceful angles, even with a 2" lift.

Good point. No amount of driveline vibrations are acceptable since they will eventually cause seal and/or bearing failures.

thanks all.

No vibes. I had them for about a week, about 3 months ago, but an allignment took care of that.

Will the dealer still honor the warrenty if I have the lift on there?
