Default Bearing Noise 2013 GT

I've been trying to resolve a bearing, wheel hub or rear axle wheel bearing noise problem on my 2013 GT. The car was a pleasure to drive till 12,000 miles. It then started making a noise best described as a whirring whine that intensifies with road speed. It increases with road speed only, so I've discounted transmission bearings or gear whine. I have taken it to the selling dealer, who was very polite and gave me a loaner for two days while they inspected and drove the car about 5 miles total, but were unable to hear it. Other than blaming the Pirellis for some minor feathering, they couldn't hear any noise. On the way home, about a 100 mile trip, I turned on my IPhone recorder and was easily able to record the noise. I sent these recordings back to the service rep who says he can't hear anything. Rather than take it back ( a 200 mile round trip) to have a technician ride with me, who apparently can't hear noises in the frequency range I can, I decided to send the clips to a friend, who, using headphones had no problem hearing them. I tried uploading them at AllFordMustangs but they won't play. On this forum there is no option to upload mp3 sounds. I sent a private message to the Ford Rep on here-Deysha- but have not had a response. What is the best way to contact Ford technical and have them listen to and try to determine what this noise is.

Gear whine will increase with speed so don't rule that out. It can also come and go with deceleration, acceleration and coasting. It can also only be present in a certain speed window.

My bearings were replaced last year, along with everything but the axles, and it was howling big time.

They make a tool that looks like a stethoscope with a long metal rod on the end that is used to be placed against various parts to isolate noise. A good shop would do this. They would put it on the lift and check parts for noise.

With a bearing, you should be able to hear from which side it comes from.

I do not take my car to the dealership for gears. In my experience, they don't do a great job and are not as particular about the amount of noise coming from a rear end. The shop I use guarantees it's work. I've had gears done there twice, both 4.10 installs, and both were flawless.

Thanks for the input, but the idea is to get it fixed under warranty. I did think of getting a "Chassis Ears" to try and pinpoint it. But at an additional $200.00 for a tool I'll never use again, I find it hard to justify the investment, after just spending $475.00 for 2 unneeded tires.

I see you sent me a PM on AFM this past Saturday, Karterfred88. Unfortunately, I don’t work weekends. In the meantime, will you please send me another PM with your full name, dealership name, and your best daytime number?
