I am a two month owner of a low mileage 2004 Boxster S. I am a retired Navy guy and in the navy we did sound cuts on lots of electrical motors and combustion engines to perform predictive analysis. Last thing we wanted was a bearing failure during deployment. I have read quite about about the IMS bearing failure etc. but no where have I read about using sound analysis to anticipate bearing wear/failure. Is this just not done?
