Good Afternoon/Evening/Morning everyone,
I have had my 2011 GT auto rear end completely rebuilt after very bad howling/grinding/whining, you name it. Old 3.15 Gears were replaced with 3.31 gears, axle bearings, seals replaced too.
One of the sounds aside from the diff howling was coming from the right aft side of the car, it didn't sound like a "whine", but more like "eeeee" that changes in pitch (onomatopoeia) with the speed, and continuous, not cyclic in nature. Think of tire noise, but higher pitch and more metallic sounding and continous, not a grinding. It was very noticeable before the axle bearing replacement and the entire rebuild. After I got the car back Friday (5 days ago), it was completely quiet from what i noticed/paid attention to. After driving around for the next few days, I was able to hear the sound coming back, although above 40 it gets drowned out by road noise until I decelerate. It isn't exceedingly loud, and unless you're listening carefully I don't think it would be noticed until about 20mph and decelerating or accelerating, without music on, but its audible over the AC if below the bottom 1/3 of blower strength. (It is NOT loud, but If you were told to listen, you should be able to hear it)
Does anyone know what this noise could be, and how to fix it? It's not a "howling" or "grinding" or anything, but it sounds localized to the right side of the car when I'm in motion, regardless of if I'm in gear or braking, turning, etc.
