Yep. Packed the crap out of my old sprocket carrier bearing the other day, was curious to see how much rust would come out in the displaced grease. Answer: lots of grease and lots of rust!! And that was only for a couple of fairly short runs. It hadn't come out past the wheel seal yet, all the displaced grease was sitting between the bearing's seal and the wheel seal. But I was quite surprised by how much had been ejected from the bearing in a short time.
