What are the odds that the bearing was bad all along and chose that moment to fail? Or is it more likely due to the seal replacement procedure having something to do with it?


Bearing play is likely the cause for the seal to fail. And the technitions should have suspected and investigated to that length.

Or, maybe it was a chevy. In which case... failures are so frequent none can be predicted.


Something clever here.
