Ratteling Noise on diagonal moves (V-Core 3.1)

Hey everyone,

I have this strange rattling noise on my printer (see attached Video). It only occures, when the printhead is moved diagnoally (so x and y on the same time) - so on Top/Bottom Layers and Infill. It´s origin seems to be the EVA Carriage. It occurs on high (150 mm/s) and low speed (35 mm/s), with accelerations below 5000 mm^2/s. X and Y moved alone don´t have a hint of this noise, even when the printhead moves much faster than stated. No resonance tuning done to it, no accel-sensor attached.

What I´ve tried so far:
Tested with no filament in the extruder to confirm that the nozzle isn´t rubbing
Checked the belt tension
Retightend all Belt Pulleys
Completly disassembled and reassembled the EVA Carriage, making sure every screw grabs a nut and is tight.

Does anyone have an Idea what to check as a next step?
