Duel Row Bearing Consensus ?

Interesting analysis, Fat mike. However, we can't lose sight of the fact that some people are literally losing sleep or at least, losing enjoyment of their cars because they are perpetually listening for suspicious noises and suspecting the worst. What value do you put on lost sleep/enjoyment of your car?

IMO this really is a personal choice and, let's face it, some people are more risk-averse than others. In any event, these discussions and the failure rates reported to Porsche should at least provide some assistance to some people in making a rational decision on the issue. And Essex, your reasons are not purely emotional, but rational. You obviously intend to keep your car for a long time and in those circumstances, as Perfectlap points out, it makes much more sense to spend money now to replace the clutch/upgrade the bearing, rather than wait.

I just had my single row 2003 IMSB replaced yesterday with 25k miles on the odometer. Bearing (and seal) was in perfect condition when removed, so maybe I was just paranoid. The cost including LN Engineering ceramic bearing, clutch and RMS was only $2386.00 plus tax.
I did however see a whole box of wasted IMS bearings and shafts at the independent shop I went to. Some were double row. I don't have any idea of how many miles were on them. Just sayin...
