Gear oil leaking front front axle breather

I have an 2001 2500 4X4. Lately, when the truck is parked, on a hot day, some gear oil leaks from the top of the front axle breather hose. I check the oil level in the diff and it is a little low but definitely not overfilled. Any idea what is causing this? It only happens on a hot day.
