[Ender 3 V3] Loud Squeaking/Screeching on X-Axis moving Right (Dry Rail or Idler?)

Hi everyone, looking for some advice on my Ender 3 V3 Se

.

The Issue:

I’m getting a loud metallic squeaking noise coming from the X-Axis. It happens mostly during high-speed travel moves, specifically when the print head moves towards the right side (idler pulley side).

Context:

This implies the Linear Rail system (not POM wheels).

Belt alignment looks okay visually.

I suspect it might be a dry linear rail or a bad bearing in the right idler pulley.

Has anyone experienced this specific noise on the V3? Should I grease the rail immediately or look into replacing the idler?

Thanks!
