When a customer brings in a car with unwanted noises what do you do? Some techs will use a screwdriver and put their ear up to it to find loose bearings.

Smart Ear can pinpoint faulty fuel injectors, hone in on a bearing noise in an alternator, or find the source of a noise coming from anywhere in the chassis, just to name a few. There are some techs that will mistakenly fix a noise that the customer wasn't complaining about which wastes time and money.
