There has to be some tell tale sign that the bearing must be replaced otherwise, 100% of Boxsters and 911s of a certain vintage have to get this work done. Didn’t Porsche claim only a minority of cars are afflicted with this issue? How can they know that if there aren’t signs to foretell doom ahead?
