I haven't heard of too many shaft failures. How much mileage do you typically see before the shaft shows enough wear to cause a fault?

Seems to be directly related to lack of oil changes and letting the car idle too much, not related to mileage.
But ya, if you go in there and see wear on the eccentric gear, better to replace it.
