Isn't the bearing failure due to the loss of a sealing ring, and then loss of the grease that's sealed in the bearing? Then inadequate engine oil lubrication to the exposed bearing results in failure. I think that's the general explanation. It would be interesting to see oil analysis on an engine where the seal has failed but the IMS has not yet failed to see if there are warning signs. I imagine the seal and the grease wouldn't have a huge impact on the oil but you never know.
