Is it oil, or is it grease ?
Did you have the final drive off, and drive shaft out ?
What do you mean by "resealed the rear dif with Honda parts "?
There is an oil seal on the driveshaft, may have been damaged if the shaft was out. (if it is 90 wt)
There is also an O ring on the flange drive, where it (wheel and drive flange) mates to the final (if it is grease) usually works its way down.
Did you recently refill the final, there is a vent tube inside the dust ring, between the final and the wheel. If it is overfilled, oil will blow out the tube.
