Well, upon closer inspection, the center support is failing. Not failed but failing. There is no noise or vibration, but I was under there checking things before bringing it to the dealer for its final warrantied service and noticed cracks around the outer edge of the rubber bushing.

Glad I checked and I have all the others here on the forum to thank for alerting me to the imminent failure.

I have 66k miles BTW.

So, my '08 turbo has 66,000 and while there is no vibration/noise, my warranty is up next month (time, not mileage).

I've scheduled a service appointment and fully expect that the center bearing will let go the day my warranty is up. I was under the car today and I was surprised at how "spongy" the support bearing was. No wonder it fails sooner than most.

Anyway, if I go in and complain of "vibration and chirping under acceleration" and leave it at that, will they simply replace the card an shaft without asking any questions? I mean given the mileage, would it be a foregone conclusion that the center bearing/cardan shaft need to be replaced.

Or should I make it fail somehow???

I hate to say it - but asking about committing fraud on the Interwebz when Porsche can easily track you down doesn't seem to be the wisest thing in the world.

Relax man! Nobody is committing fraud.

I'm just trying to make sure that with 66,000 miles I'm not going to get stuck with a $1,500 out-of-warranty repair of something that is known to fail at this mileage.

Just so happens that the outer rubber was already separating from the center support, so it's a non issue. It was already failing.

I think the takeaway from my contribution to the thread is that even if you have no vibration or chirping, everyone should closely inspect the cardan shaft center support bearing (in particular the soft rubber cushion supporting the bearing). Maybe my experience could help save somebody some $$$$ if they know what to check for (even of everything seems fine).
