How to get Porsche replace my 2005 987 Porsche engine IMS bearing failure at 42023 mi

[QUOTE=Boxeer;280133]IMS bearing is removable:

Chewed up bearing support:




That should be Porsche logo:




Why is the bearing completely dry? Any seal pieces in there? Do you have a pic down the IMS shaft.
I don't think you could sue porsche directly, you would have to go after NSK for producing defective bearings causing more than 10,000$ in damages(leading to a class action). Then NSK would probably be forced into release the info implicating porsche and THIER design of the IMS bearing. I'm no lawyer, but I did play one in a 6th grade play.

It is a good idea but I don't think the bearing design/quality can be put in relationship. As a mechanical engineer I have to choose bearing sometime and it is my responsibility to choose the right one that match my application. They just screwd the design deeply and they are ignoring it. It's already a miracle that the bearing did last 42k.

The use of a bearing was just a bad choice as it is impossible to quantify the play of it and plan a replacement before failure happens. A bearing has an L10:

That is true, and you have an off the shelf single row bearing. I'm no lawyer, but, I would think one could back door porsche through the bearing company as the original bearings are a custom design (OEM) by porsche built by NSK and not available to the public. I am sure NSK documents, emails, drawings, etc. will show the flaws of a design reported to porsche most likely before during and after the failures took place. Hence we come to the off the shelf of the single row bearing, and the replacement engine bearing, 2 different designs used at the same time, 1 design to use up stock (single row) even though it was a flawed design. I am sure that a lawsuit would have to come Texas as their laws provide for a pre lawsuit subpoena of all evidence to see if a lawsuit is viable.

an interesting strategy. One often used in criminal cases. Go after the enablers who don't have the resources of the ring leader.
