Per Kevin's point, he didn't attempt to inspect these and I don't remember why he singled these out, but he knew the transmission had been club raced and would continue to be used on track. So, maybe it was a preemptive measure, given the high loading on these bearings. I also installed the Wevo one-piece bearing retainer plate.

The perspective is different when you're a shop owner servicing a customer's transmission (or engine, or ...). If I (as one such shop owner) press you to replace the iffy bearings, you'll grumble until your first lap on-track. If I don't, and the transmission has to come back out, you'll hate me forever!
