my 2007 gx470 has had this whine since the day I bought it. I had it looked at when it appeared and was told by my mechanic that it is common and nothing to worry about. He said it is likely a vibration in the differential and they all do it just some more noticeable than others. There is a dampener attached to the bottom of the diff which was supposed to make it less noticeable but is not always effective. I now have 160K on the vehicle and the sound is exactly the same and has not changed. I am totally not even worried about it any more!!!

I had not read that this was flagged in forum discussions, so when I heard this ... between 55-65 MPH ... I worked the accelerator pedal and listened to the sound level to assess and concluded that it is not an issue given the sound was very faint, but will continue to listen and report back.

2019 with 3k miles ... yes, the faint whine is between 50-60 MPH in the transition zone between accelerating and decelerating where there is no load on the drivetrain ... sounds exactly like a ring-and-pinion gear setup issue.

I have a 2013 with 80,000 miles and have the same issue. When I changed the diff fluids, the noise changed but did not go away, so I am with ASE in thinking this is a ring and pinion or the pinion bearing. I haven't tried taking it to a dealer, interested in what CB84 hears back.

I have a 2014 Lexus GX460 with 64,000 miles. I hear a low volume, high pitch sound that appears to be coming from the backseat area of the car. It's constant, doesn't ever get louder or softer. And when I shut off the car, the sound continues for about another 10 seconds or so, then just goes off. Any thoughts as to what can be causing this?
