It did in my case, I hope I wont regret it but Ims bearing change has gone down my to do list. I have a 99 so I understand that mine is dual row so less potential. I will still do it for sure at time of Clutch change. So I still have the intention to do it but later.

I don't know the details of the P lawsuit but I am not planning any imsb replacement until I do the clutch. I have a 2001 Box base and my IMS Guardian will likely warn me of impending failure. Clutch at 40k miles should last a few more years. Drive on. Be happy. Life is for living.

How do you know if you have dual or single row bearing and which years are more apt to fail. 2002 S

The failure rate released by Porsche as part of the discovery process during the recently settled class-action suit make clear that these cars are not all ticking timb-bombs: dual-row bearings had a failure rate of much less than 1% and single-row bearings between 8-10%. Obviously a dual-row bearing is much less of an issue than a single-row: indeed, the plaintiff's made use of the reliability of that bearing in making out their case regarding the negligent design of the subsequent single-row bearing. Understandably, it is only the single-row bearing that was the subject of the class-action suit settlement: a failure rate of much less than 1% of any engine component, regardless of mileage/maintenance, can hardly be considered surprising.
