Hello form. I have the above mentioned vehicle. Around 40 miles an hour attend to hear this high-pitched noise. I used to tone generator and realized it was about 2800 or 2900 Hz. It tends to happen around 40 miles an hour. From what I’ve read on these prior post, most people seem to think it is a rear differential bearing failure. I have attached an audio file for you to hear. Tell me if you think that’s what this problem is. Thank you in advance
