y-axis noise on x-axis shaper

please some one help me, I lost sleep over the past week trying to resolve this

Here are the specs of my printer
Vcore 400 with carbon fibre beam
Recently upgraded to cnc-ed VZ-printhead and brs m1 l3ver tensioner
Vz-hextrudort and Goliath air cooled hotend
Using an adxl345 mounted on the nozzle using mellow clamp mount

Belts are tuned using BRS belt guide to 70hz

The belt tension graph shows almost aligned double peak with some binding perhaps on the lower belt?

But what's interesting is the x/y axis. On x-axis, there is a peak around 85-90hz on the y-axis on the accelerometer. Somehow vibrating left and right is triggering resonance on the nozzle head in the y direction.
If we move to the y-axis graph, there is the same peak.

Solutions that I have attempted :
I have detached my wire loom
I have searched for loose bolts to no avail (though I think the graphs indicates loose bolt?)
I have tighten/loosen the belt
Checked that my gantry is parallel to the front of my printer
