Don't judge a book by its cover..

Stage 1 failure had already occurred and that nasty black oil that was found inside the bearing is proof that the outer seal had already failed and allowed engine oil to wash the permanent lubricant away. This is what starts the snowball headed to hell and we have known it for years.

Your bearing had already failed.. But it felt fine? Yep. The difference was that collateral damages are not symptomatic until stage II bearing failure.

When the seal fails the degradation has begun already..
