Constant whining noise from rear? wheels

Hello everyone, I have a 15 plate Giulietta QV Line 1.4 that has (for approx 2 months) emitted a whine from around the rear left wheel. It does not start straight away, may be takes a few miles, it is noticeable from low to medium speeds. If I tweak the steering it seems to subside a bit but then continues. I have driven with a mechanic on 2 occasions but initially he could not hear anything of concern but latterly did hear it and could not decide what it was, not wheel bearing or road noise though. Does anyone have an idea taking into account my information here. Any thoughts would be very much appreciated.

Try swapping the wheel to eliminate tyre issues, failing that it has to be wheel bearing noise as not a lot else could cause a whine.

Sticking brake caliper also a possibility.

Had the same on mine over the last week or so, I also had the low pad light come on so an investigation may be in order.

I've had the same on the driver's side rear for a while. Took to two separate garages and both could hear it but neither could find any issues. Replaced bearing but didn't help.

Mine is most noticeable above 50. Have done serious mileage since noticing it (and promptly having two garages look at it) and hasn't gotten worse. Next service I'm going to get the wheels swapped over to see if that helps.

Funnily enough Ive had this issue today, my wheel bearing is fine but my MOT guy pointed out the inner tread of my G's rear tyres have gone to a saw-tooth style of wear, this is my issue - run your hand along the inner edge of the tyre, giuliettas are well documented for rear tyre wear because of the camber at the back

As Zoo says, check the rear tyres. They can develop a suble uneven wear which causes a speed-related rumble. Happened on the 147s as well. Just swap the front and rears for a low cost diagnosis. (Don't swap the the rears with each other: most tyres have a rotation direction).

Still heartbreaking throwing away tyres with plenty of tread though!

Thanks for reporting back. Hoping that's my issue also.

Ok thanks to all for your advice, I did swap front to rear tyre recently and the noise was still there. The rear right did have a strange fault on the tread pattern the garage thought possibly a brake issue had caused this so I will get the brakes checked, this said it did have a service recently and this was not picked up.

I have never had this tyre issue on my Giulietta.

But I do rotate the tyres front to rear every now and again to even up the wear.

Changed my wheels front to rear the other day and it now sounds terrible at the front, the only thing I can guess is because my car is lowered is that the rears have worn unevenly so now they are on the front it made it worse. They are nearly ready for replacement wear wise. ( I know I didn't think about the camber and uneven wear before changing them).

I had this, It was the wheel bearing.

Chock the front wheels, disengage the handbrake then Raise the rear of the vehicle and rotate each wheel by hand. They should both be completely silent. In my case, one wasn't.

New front tyres today and the noise has gone, new rear tyre's going on tomorrow.

OK everybody, the whining has been sorted. The fault was brakes dragging. When the local garage dealt with the brakes he found that a couple of pads had worn paper thin and they had been binding. After a number of services by Alfa dealers and lately a few weeks ago by an Alfa specialist, the local mechanic has concluded that the brakes had never been striped, cleaned or even looked at since new! (40 K miles and 4 Yrs)
So wider issues than a whining noise. Hope this helps all you who may have the same problem.
