I've done some searching and have determined that my Pinon Seal is leaking. From what I read, leaks could be caused by pressure building up from clogged differential breathers. What is happening is as soon as I stop it drips pretty quickly, but as time goes on, it slows down. Could a clogged breather be the cause of my leak?

I haven't looked yet, but is it easy to find where the breather is located? How should I go about cleaning it out?

 

Breather is on top of the axle just as it starts to transition to the "tube" portion on the drivers side.

The seal wears out from use and starts leaking. (even if you dont have a plugged breather) It could leak less as the parts warm up and expand a fuz.

Its entirely possible there is nothing wrong and its just worn out which means the only fix is to replace it.
