Default High pitched noise (bearing?) on X axis.

Im noticing a very faint high pitched noise coming from my Cobra. It's so faint can hardly identify the exact source of the noise, but I suspect it is a bearing on the "left side" X axis of the machine. I primarily hear it when the machine is moving at high speed to change tools or begin a new cut.

It does not effect cut quality and I keep my linear bearings lubricated. Any tips to diagnose where the noise is coming from - I'd like to have parts on standby before it becomes a bigger issue.

Id start by cleaning the gear rails. Scraping out the packed teeth. Then be sure everything is lubed.
