Gear oil leak after drive

I drove the Yj 100miles non stop (it's longest non stop journey since I have owned it) when I stoped the rear dif was covered in gear oil it had also sprayed all over the gas tank skid I checked the oil level in the dif and it was full. But where did all this oil come from? I have had the jeep for a little bit put about 3k miles on it and not a problem. All 100 miles were freeway at about 65-70 mph.

I've had rearend seals leak but they didn't spray oil every where. There would just be oil on the bottom of the rearend. Is there oil on the front of the trans or differ?

Check your diff vent line. If it is plugged when you drive long distance fluid heats up and creates pressure thus pushing gear oil out the seals

This must be it cause I don't see a vent line on the diff at all. Do I just drill and tap a nipple? Just like you would for an air locker?

Vent line is on the driver side of the axle tubes, not on the pumpkin...runs up behind the fuel fill..

You said it was full when you checked..ie when you pulled the fill plug it poured dripped out? or did you have to stick your finger in to feel the level...

Although hard to do it can be over filled...

The vent line usually goes right up the middle of the brake line T where the flex line connects to the rear diff. Take it off the frame, there is a plastic cap on it. This gets plugged with mud and crud. Clean it and blow through it to make sure it is clear
