My car was not in the "higher probability of failure" group due to it's history: Daily driven with frequent oil changes and meticulous maintenance for the first 5 years, Calif. car.
I replaced the IMS while doing other clutch/trans work at 98k miles. The original bearing looked to be in very good condition.
If I had a 10 yr old garage queen with very low miles and long oil change intervals I would be more concerned.
