  1. I replaced the cardan shaft on my 04 Cayenne S. The original bearing support was broken. The car has only 28K miles, but I guess the Texas heat did not help. I bought the reconditioned shaft from Vertex, which includes a free flex disk for $350. I installed it a couple weeks ago. I had pretty strong vibrations with the new shaft, especially at low speed between 19~23 mph. At higher speeds they went away, but I was not happy. Those vibrations were really annoying, especially in traffic where you stay in that range for long periods. Then I remembered than during the installation, putting the bolts through the flex disk was unusually hard, like they were not lined up properly, while removing the bolts from the original disc was easy. So today I replaced the flex disk with my original one, which still looked really good (again, just 28K miles). Looking at both flex discs closely, the original Porsche disk is different, especially where the metal meets the rubber. Definitely better quality. The porsche disc went back in really easy, the bolts lined up properly. And the vibrations went away. The car is really smooth now. Different car ! :-) BTW I made an alignment tool from a $3.50 PVC fitting (-edit- 1.5" x 3" coupler) that I bored a little on the lathe and then cut in half. It made the alignment of the bearing easy. Conclusion : if you order the reconditioned shaft from Vertex, put the flex disc in the trash, and get one from the dealer (unless you can reuse your original one). The alternate brands are not the same in terms of quality !
