JROC,
Here's my guess on what happened. You *may* have overfilled the birfield chamber 8 months ago, and when the wheel bearing went while you were driving (never did say how far/long - I'm guessing highway trip?) it generated a great deal of heat throughout the knuckle/hub assembly. At some point, it got so hot the pressure built up enough that a large quantity of knuckle grease was forced out through your properly installed outer triple seal set.
Another less likely scenario may have played out if you have not done the front diff breather mod to remove the little one way flapper valve. In this scenario, the front diff oil got extremely hot (front tires different sizes by chance?) and the breather is plugged. The resulting pressure built up until it rapidly forced a large amount of hot gear oil past the inner seal, which in turn blew a bunch of grease/oil out of the triple outer seal. In this scenario, the front wheel bearing problem is unrelated and you happened to note it when examining things closely.
