V-Core 4 500 IDEX Peak at 125hz

Here are my current Tension and IS results. I have this peak at about 125hz at Y and I dont know how to get rid of it. I already reassembled both toolheads and checked for loose bolts etc. on the gantry. I got all the toolhead wires and umbilical ziptied and secured (I'm on my second pack of zipties 🗿) The idlers are the Ratrig heavy duty idlers. Dont know what else to check 🫠

Solution
After about 3 months of hunting this down it was the whole rear panel vibrating at 125hz 🥲
