Ok I have a 97 4x4 with the 5.4. The truck has sat in the same spot for the last two days and I get home from work a bit ago to see that the breather tube on the front diferential is leaking fluid everywhere.
About a montha ago it did the same thing, so I drained all of the fluid and replaced it with fresh oil. Like I said, it has sat for two days and its around 60 deg outside. Anyone have an idea as to why this is happening?

Thanks in advance.
