Those Funny Car Sounds

As you drive your vehicle, be aware of its operating characteristics and normal sounds from the engine, transmission, driveline, exhaust system and tires. Excessively loud or abnormal sounds fall into the category of "noises." These can be very helpful to service technicians when diagnosing the cause of a problem.
