Throughout these forums, recommendations made by some members are to disassemble or tear components apart to verify faults, wear and tear and malfunctions similar to autopsies performed on dead bodies. Imagine our healthcare performed by our car "doctors". A possibly healthy car gets killed in the process of what they say as "diagnosis" performed as an autopsy. Car owners beware of this. Guesswork or unnecessary tear down by incompetent diagnosticians( morticians) is not the norm
