Hello people.
Just got back from a local garage who couldn't find an issue with a droning and humming which starts at about 40mph and progressively gets obtrusively loud at (let's call it 70mph). Ftype s with 40K. Tyres are all good I'm told. Came on all of a sudden last week. Slide into N at any speed and the noise is the same and completely speed-dependent, the higher the speed = much more noise. It seems low mileage for wheel bearings. I hear the dif issue is a whine so fingers crossed that's not it. Any known issues before I try another garage? Much appreciated.
Very loud droning at the front
Wonder if it’s a loose bit of trim…
Forces due to wind and turbulence def go massively with speed
I’d get it up on a ramp at a friendly garage and check all the under trays etc
If you have a leaf blower you could point it underneath on full blast
Although you’d think where you sent in would have checked that first
Sounds like sound level is car speed not engine speed related - guess could drive shaft/diff etc
Could put into neutral a see if changes at all

You don’t say if it’s 2/4WD, engine. All helps diagnose and eliminates various things
Prop shaft is a good one to check out as and very easy. They really do drone and are speed related.
Wheel bearings mentioned and can deteriorate very quickly. You tend not to notice then suddenly you can’t fail to hear it as you tune in.
Check if it’s load related on faster long corners
