The bearings don't come to me, they go to LN.. My part of the classic retrofit bearings has been over for a long, long time now.

How does the original bearing failing impact a new bearing? And what's an expected life for a replacement bearing if the original is failing...at least long enough to make the replacement worth it?

Debris from the original failure will remain within the engine, being very difficult to remove. These will chew the internals of the engine, and the retrofit bearing to bits.
If a bearing failed, the IMS assembly can also be compromised as it can see collateral damage in the form of housing runout. This can easily create a wobble and harmonic that will shred the retrofit bearing in short order.
This is why preventative retrofits are the only way to go- people won't listen to this until they have wasted 20K by thinking that it can't happen to them.
I have two "criers" this week... Those are failure calls where the owner starts crying.
