Hi
I would really appreciate any help or advice on this...
My UK 2016 i30 makes a squeaking/squealing sound as the wheels rotate but only after driving for some time eg 1/2 hour, and after coming down a very steep hill! It usually persists for some time after this.
I have had brakes and pads replaced but it was there before and after this work, although it is slightly higher-pitched now and appears more noticeable when reversing. I had taken the car in to the dealer but they couldn't find anything obvious and the sound wasn't there when they had the car.
I have tried to video it and you can hear the sound -kind of chirping in forwards and more metallic in reverse (although slightly muffled by the ambient sounds of driving with the windows open)- YouTube links:
It doesn't seem to change when braking so I think its something to do with the wheels/rotation/bearings...
Any ideas and thoughts of how to confirm what the issue is?
many thanks
