Thanks everyone for all this valuable info. I'm the guy selling this car and there is a lot I just learned here as well. There seems to be many different opinions on the subject. I worked for SKF bearings for over 30 yrs both in USA and Europe. I have been in touch with the bearing application engineers involved and have had discussion with Charles at LN. I don't agree that an open bearing is the answer. The bearing is designed to be sealed with a specific grease. The problem has been the seal failing and the grease purging which causes the bearing to fail. There are many cars here that have 100K miles plus. I think that if the RPMs are kept up and proper warmup is allowed then that should help minimize the problem. Question is how many of these cars have failed? Which design did they have? I don't think Porsche wants all that made public but I still think the % is very low. Just my opinion.
