It sounds like it's coming from the front wheel, is that a bigger problem or the same? Clueless when it comes to new things going wrong haha.
Double check,jack car up and grab wheel at 12 and 6 and wiggle,you will feel play.
I've had the same thing and it turned out to be the tyres too. Is the noise still there if you put the clutch in?
It gets louder when I'm braking/coming to a stop. Any ideas?
Not yet mate. Mine's the same, over 40mph and when braking to a stop you can hear a loud droning noise. My mate said it sounds nothing like a wheel bearing though so no idea what it is.
