Does anybody know what might be causing this sound?

[Mc21727]

 

sounds like a squeaky rocking chair or something but really quiet.

speeds up when moving faster, slows right down and drags on longer when slowing right down, sounds like it’s coming from front left. Any help would be a appreciated thanks.

have parked up and no longer driving however just wondering if anyone knows what might be causing it.
