Anyone heard of driveline problems?

I have a whine coming from what sounds like the middle or rear of the car. (It's kind of hard to pinpoint exactly where it's coming from). At highway speeds, there is a whine if I am not accelerating or decelerating. I can find that spot with the accelerator where there is no power being applied, nor is there any engine braking going on. It generally takes 5 miles or so of driving before this starts happening. It has gotten worse the last year or so. I have had the differential looked at and changed the fluid. Nothing in the fluid drained that would indicate anything wrong with the diff. It seems to me like the CV joint on the end of the drive line, or maybe the carrier bearing in the middle. Anyway, does my description sound like this is the likely problem? The tone of the whine is consistent with road speed, not engine speed.

Sounds like a bad carrier bearing, although the noise is more of a howling/groaning rather than a high pitched whining.

Yeah, I'm not sure if "whine" is the best way to describe it. Maybe a howl. Not groaning though. I heard some howling and groaning from my neighbors the other night, but that's probably different.
I'm just checking here in hopes someone has some personal experience with this. I'm hoping that's what it is, since that would be the simplest fix of all the possibilities. Probably the worst case scenario would be a problem within the back end of the DCT.

Typical M3 diff whine. It's normal actually.

My differential was replaced under warranty and it started doing it again a few months later haha.

I wouldn't worry about it.

I replaced my diff at 71k due to bad input bearing. It was making similar noise you describe and I assumed wheel bearings. The input bearing is serviceable if you're mechanically inclined and runs about $100 in parts. I bought a salvage 16k mile diff with the idea to rebuild my original into a 4.10.

The howling and the groaning from your neighbors was when you started the car up and they were thinking they'd have to listen to your car whining...
