I've got many, many thousands of miles on my FWs over the years. I've never lost a bearing. This is detective work. As posted above, it could be an inept installation job, incorrect application of grease, or the wrong grease.
But something else to consider is who replaced your bearings in the first place. If your bearings went out in the past, and they were replaced, then the race SHOULD have been replaced too. If they just slapped a new bearing in, but didn't replace the bearing race (the part the bearing mates with) then another failure is pre-ordained. Other things to consider were if they also replaced the grease seal. If not, the grease could have heated up and leaked past the seal which would leave a dry bearing.
