Simple answer is. It was a POS bearing design. Farmed out to questionable, at best manufacture's. Porsche was about ready to go broke, due to lack of sales. The Boxster was going to be there savior. It was hurried on the market place to accomplish it. Little research and development was done.
For what ever reason. The general consensus is. These cars need to be driven. Another words. Drive the piss out of it. I guess is some ways, it may keep the bearing moving and may prevent the crap materials from absorbing the containments in oil to deteriorate it. In any case. It is was poorly done. Some are lucky. The one in there car are ride on. Some suck. To ponder why, is irrelevant. Hope yours does not go bad. Mine has 106,500 miles on it and lives. A bunch of other crap parts have failed. But not that fatal one... I love to drive it. But that failure is always in the back of my mind.
Now off to fix taco's for dinner. With a proven method.

PS, The LN bearing still seems the best answer to prevent this. But at what cost? I'm not spending 3k to prevent an 8k car from blowing up. I can part it out and break even...
