You should upload the latest klippy.log so we can see what you have configured.
Can you upload a photo of the issue and details about speed, filament and so on?
Also remember that vibration on the Y axis shows up as ghosting on a surface parallel to the X axis. Conversely is you see ringing in a surface parallel to the Y axis you need to “fix” the X axis.
Next time please directly attach the klippy.log to your post!
If it is too big you can zip it. Best is to roll it over so only the last session is logged.
If I read your log right you set MZV shaper type for both axes. This should have no vibrations left regarding to the shaper theory in the graphs.
If I remember correctly 4WD might be suffering more from ghosting than 2WD/standard. But I don’t know if that is really true, could be only true for VFA though. Quite a long time I did not further deal with that topic.
However, the noise around 100-125 Hz on the Y shaper graph could be something loose on the print head or even a fan (fan rotor moving on the shaft).
Can you post a photo of the print head itself? Does it wiggle on the rail?
For example: when I fasten the print head of my V0 on the rail carrier, the whole thing wiggles on the linear rail. If I loosen the screws a bit it is fine!
So check every screw, fan parts and stuff and check the whole print head.
There is a Klipper plugin called Shake&Tune that extensively analyzes vibrations and stuff and there is a special thread on the Voron Discord.
But like here: if you won’t give enough pieces of information they can’t/won’t help you.
