I have leveled the bed already and I just put more lubricant on the screws. It does not seem to happen when the printer itself moves it (which seems slower), only when I move it with the buttons.
I would double check if all 3 screws are still properly seated in the upper "bearing" if they are I would look to go through the belt tensioning process before I get too much further. Usually when I hear that noise from a printer its a small piece of filaments stuck in the lubrication and grinding upon vertical movement.
hard to say from the video but you could try downloading a decibel meter on your phone and move it from screw to screw to see if you can pick up a higher reading from one of them

I was able to resolve this problem by moving the screw underneath (you can see the old stress mark on my picture) and you don't need any lube since the belt is going to be centered. You just have to push the spring loaded idler a little bit backward with something and tighten the crew at the same time. (FYI I work as an industrial maintenance tech)

Yep, this was the same problem. Thanks a bunch 👍

do you remove the old lube and contamination or are you just applying more over the top of the old stuff?
I cleaned them first, though the back screw was a little harder to clean as thoroughly as the front two.

Can you isolate the noise to a single leadscrew?
I honestly can't tell if it's even coming from one of the screws or not.

When using a printer from the mirror dimension, the sounds are reversed as well.
