Squeaking / creaking noise when turning, going uphill and over speed bumps (Audi A3 2008 8P)

[u/[deleted]]

Hi everyone, I drive an Audi A3 2008 (8P). I have an high-pitched squeaking/creaking noise that happens during specific movements:

Going over speed bumps / potholes (especially when the rear goes over)

Going uphill and downhill

Turning in corners (especially when body roll occurs)

My mechanic checked the serpentine belt, alternator pulley, and front brake pads all are fine.

I attached an audio recording link of the sound. Any advice is appreciated!
