I have a noise from the front of my motor, A RAV 4. It is a highish pitched whine (sounds like good old landrover tyres or the kind of noise you get on a stretch of concrete carriageway). it isn’t engine rev dependant, it just gets louder the faster you go. I have dropped the clutch at speed to confirm this.
If I turn the steering wheel 5 degrees to the left, it stops. Patently it is something on the front drivetrain. Thinking Diff, CVs or wheel bearing.
the last few times i’ve had wheel bearingy type noises on a car it’s actually turned out to be tyres. Tried all the tricks, road / engine speed dependant check, turn wheel noise changes / stops check… yep wheel bearing… nope tyres.
Might be worth trying taking the brake pads out and filing a chamfer on the edges before condemning the wheel bearings. Sometimes they can wear a sharp edge on the side which whines as it runs on the brake disk. This will also stop when you steer other than straight ahead, IME, and also when you lightly touch the brake pedal.
Otherwise, wheel bearings / CV joints would be worth checking, as said.
