If you have doubts as to any diagnostic that a mechanic offers, the fastest way to learn the truth is to simply ask the mechanic to show you the failure; that is, prove it to you. If he does, great - your problem is solved. If instead he or she gives you an excuse, like you can't go in the shop, then there is nothing wrong with your car.

Typically, in a control arm, there will be rubber bushings and a ball joint. Your vehicle has relatively low miles and so it would not be unreasonable to be suspicious as to whether there is a failure or not in the suspension components. Wheel bearing failures have to be carefully diagnosed. Lots of rotating assemblies in a car make noise, not to mention the tires if they have a defect. Consequently, with regard to the bearings, the mechanic should be able to tell you which side, front or rear, and what the symptoms are.

In order to pinpoint a wheel bearing failure, sometimes electronic chassis ears have to be used to compare noise from side to side. At any rate, if the failure of a vehicle part is not actually demonstrated to you, you will have no reasonable assurance that they have actually correctly diagnosed the problem. Should you desire a second opinion, by all means contact YourMechanic and a certified professional will carefully evaluate the issues you are having during a noise inspection.
