Harmonic Noise
#31
And it's probably no coincidence that I like F-15 "light blue (in the old days)/ gray" (otherwise known as Polar Silver... it was as close as I could get)

Thanks Buzz. Colon cancer got him in his 50's
The worst part was he got regular screening, had a few polyps, was treated and was declared cancer free and then out of nowhere it came back, and with a vengeance. Damn I hate cancer.
Cancer can't take the amazing memories I have of him

Hate to bring this thread back from the dead, but did you find any resolution to this noise?
I've been experiencing a similar noise - from about 2300-3000 RPM engine speed regardless of road speed. I just had my oil changed (5k intervals since I bought the car two years ago), and had them look for the source of the noise - including the wheel bearings.
I've also been experiencing greater oil consumption lately - had been 2000-3000 miles/qt, now < 700 miles/qt.
They reported no problems with the wheel bearings, and gave the old "they all sound like that" line.

UPDATE
Your timing is very good on bringing this thread back. Yesterday I had the differential fluid replaced in both differentials....it was the original fluid (8 years old), and I had it replaced as a preventive measure. When I took the car out for some spirited back-roads driving, the harmonic noise is now reduced by about 75%........I didn't expect that, and it may not stay that way, but I was very surprised. There is still a little noise....now down at 2100-2250 RPM instead of 2300-2750 RPM, but not nearly as pronounced as before. I don't guarantee this will work for you, or that it will last, but I was pleasantly surprised by the results. I will take it out again today to do some more 'testing'. It is not a 'cheap' solution....it cost me $411....but so far, so good.
