Yes my front diff seal is weeping and when I asked a couple of months back about changing it I was told a special tool was required to do this and it was not available.Was under the truck yesterday and my front diff is "seeping" at the yoke seal at leading side of front prop shaft. There was enough to form drips that I had to wipe off. Anyone else have that going on? Hard to see in the pic, but concerning with only 3k miles. I'm assuming that the driveline vibration at 2000 rpm is beginning to take out that seal. Don't know how the design got through all that testing without caring about the known vibration at 2000 rpm anytime under load. I live in the mountains and every time I go somewhere, seems like it's at that rpm. LOL
