there was an interesting post by Doug recently about his take on how the front diff will suck grease in through worn axle seals when it generates a vacuum.
Interesting concept!
Is that a well-known fact or Doug breaking new ground?
turns out I checked the front diff oil yesterday, it was black and greasy looking. Annoying! Yet, there is no indication of leaking at the knuckles. Could this resullt from overfilling the knuckles too?
So according to Doug's theory, this could be caused by the vent being plugged. Tried to look under there (no FSM yet) and saw that the vent is going to some sort of smallish boxy part. Perhaps some valve affair?
Soo, how do I make sure this vent is not plugged and how to unplug it if it is?
thanks
