My FWD car is exhibiting a speed-dependent (especially noticeable at highway speeds, around 90-110km/h) hum/whine, accompanied by a slight vibration noticeable at the steering wheel.
The symptoms do not change when I depress the clutch or shift to neutral. The symptoms immediately appeared after I did a hard brake of the car, that involved wheel lock (I have a faulty ABS that I need to fix) and a skid of the car on a completely dry asphalt road.
I was wondering whether these symptoms are due to tire damage (due to the skidding and/or excessive lateral forces on the side walls) or mechanical damage to the car (e.g. wheel bearing).
What differential diagnosis can I do to try and pinpoint the problem?
