My car makes a whining noise from 65 to 80 mph in the rear. I'm almost 100% positive its the diff bearings.

[dogsbark26]

Hard tellin'. My iX makes more drive train noise than two-wheel drive cars.

If it's coming from the back most likely candidates are rear differential or wheel bearings. Does the whine change when cornering?

Good luck with vibration. I replaced many suspension parts, rebuilt driveshaft, and straightened wheels before mine finally subsided.

I'm gonna agree with Click. Differential bearings.

If you need a new diff I have a couple for sale. Also, check the rear driveshaft joints
