mine was toast by 70K miles, as was the flywheel. At which point I upgraded to the LNE dual row IMS bearing and replaced the RMS with the Cayenne unit.
Pricey repair, first time I ever forked over $3K plus on anything that wasn't an engine or transmission rebuild. My original dual row bearing looked solid from the outside but that's not really a good metric to go by.
Even if my clutch hadn't been on its very last legs I would have have done the IMS bearing and clutch prematurely. No point putting it off in my mind just to save a few hundred bucks in extra clutch mileage. This upgrade is one of the few that both addresses a weak spot while providing utility -- you get a new clutch out of the way and are good to go for a long time.
