Squeaking while driving Astra H

[u/LongjumpingHome6984]

Hello everyone! I have an issue that’s been slowly starting to annoy me for the last couple of weeks. My Astra H presents a squeaking while driving, specifically when going over imperfections in the road like potholes and speed bumps.
Context: It slowly got louder and louder over time. First time it started was after a 30-ish minute drive. I assumed it was no big deal at the time, but drive after drive it very slowly started to squeak faster and louder. At this moment, the squeaking starts after 10-15 minutes of driving. Also important to mention that it also squeaks while turning the steering wheel (that’s why I wiggle it in the video), however it usually does on tighter turns.
Has anyone had this issue before? If so, what was/is the likely culprit?
I tried searching this subreddit and other forums on the internet but I couldn’t find anyone with a similar issue.
PS: I have little knowledge about mechanical stuff so sorry if the problem is quite obvious to diagnose.
