Well...I have read all 400 posts on this thread, which began years ago with: "For the past 4 weeks i have been getting a noticeable humming sound when driving from 60-75MPH. Only when you coast then feather the gas peddle to stay around that 60-75 mark."
This is exactly what my 85K red needle '18 is doing. The very light rumble-strip hum in top gear and only under light throttle. If you back out of the gas, the noise stops.
It is NOT making any groaning noise when turning or any of the other awful sounds described.
My question is - is the straight line hum the beginning? Will it graduate to the growling when turning, etc., and is that the consensus that the first attempt at resolution should be changing rear diff with GM product, making sure it's totally full and not leaking?
Thanks all. I really love my car, other than this.
