Jusr flat towed my CJ7 100 miles. Dropped driveshaft. When I got to there I looked and the front seal on diff was leaking. Is that bad luck or did I do something wring. It pretty warm too.

If you didn't have the hubs locked it would have nothing to do with it being towed.
 
You might check that your vent is working and not pluged.
 
If it's leaking then you still have oil in it. I would say that it's just some bad luck. Check the bearing to make sure that isn't what made the seal go. Try to move the pinion up and down and if it does move you need to replace the bearing along with the seal.
 
Thanks for the replies. I checked the fluid and topped it off. Wasnt that low. Im just gonna watch the level. I think it is just the seal.
 
Is there ANY side to side or front to back play in the pinion yoke.
DON'T be gentle when check'n for this.
A seal leaks for a reason-----

No. Movement. I drove it all last night 60mph and seemed fine. There is oil some oil thrown around underneath. But this morning there wasnt even a puddle or a drop for that matter.

Make dang sure the vent for the axle is good.

Where is it?

You should see a hose coming off the top of the axle that goes up above the frame with a one way valve in the end of it.
