Technical Wheel whining noise

[Daughters500]

My daughter has a 1.2 500 2011. It’s my nemesis. There is a noise coming from front end when over 10 - 15mph. I have changed the wheel bearings, wasn’t that. Gearbox has had the bearing done and that hasn’t fixed it although the bearing noise in 4th gear has gone. It is constant noise (stays when clutch is on or out). It is a whirring noise that has a slight vibration through the floor. Hoping it isn’t the driveshafts as not been a problem with them before. Anyone any ideas? Tyres have tread but are cheap ones so maybe them?

If the rear tyres are not the same brand then swap the wheels front to back and see if it makes any difference!

Plus if you live near a long steep hill you could try rolling down in neutral to eliminate drive line parts!

Is the noise the same regardless of which gear you are in?

Drive slowly with the car on full lock; do this both ways. This can sometimes show up driveshaft issues.

Can you make a video so we could hear the noise?

I have done the roll in down in neutral and the noise remains in neutral. The engine was running but not in gear. I am thinking that rules out gearbox and engine.

yes any gear above 15mph. It’s not the 4th and 5th gear bearing issue as that has been swapped out and that noise went away. Hoping it’s not something in the diff that has gone wrong.

check the inside and outside edges of the tyres for witness marks that would suggest rubbing on another component.

Isn't it a belt noise?

try a light dusting of talcum powder on the alternator belt if it goes quiet then thats it! if not then a mechanics stethoscope on the timing casing will show if its that.
