Q: Car make whining noise

asked by on

My car is making a loud whining noise when I'm driving. Is it the rear differential?

Hello. You could have damaged parts in the differential. You could also have a bad axle or bad wheel bearings installed. A test drive can help pinpoint exactly where the noise is coming from. I would also suggest having an inspection of the rear drive train. They will be able to diagnose the noise and recommend the proper repairs for your vehicle.
