I just replaced my axle shaft seals on my Dana 44 high pinion. We changed the oil in the diff and sealed up the cover really good; easy stuff. Well, it's been a little warm where I live, about 105-111 degrees and the stupid seal started leaking worst than before I replaced them! It leaks no matter what direction I park my truck in (only passenger side). I made sure I cleaned out the vent really good and it was plugged up pretty bad (still leaks). Today it was a very cool day, and it didn't leak a drop? I know old truck are ALWAYS going to have some leaks, but I don't need to mess up the gears in my differential. I didn't know if there was an easy fix before I tear it all apart again. This is my FIRST vehicle, so I'm still getting the hang of things. Help is much appreciated.

Thanks for reading!!
