Toolhead carriage clicking noise in middle of gantry

Anyone else ever hear this clicking sound as their toolhead moves along the X gantry? You can hear it at 0:03 and 0:18 in the clip https://photos.app.goo.gl/Z4HyQHudLK7f4eVW6

Solution:
I've isolated the problem to the rear idler on the XY joiner. If I just barely touch the idler as te carriage is moving left to right, the noise goes away

Glad you found it, I had the same issue with a 3 month old Funssor Heavy Duty idler. Since the idlers were new it was the last thing I started checking.
