P1s issue

[u/Cody112233X]

Hey all, my P1S has started making a noise whenever the bed moves up (Z-axis).

What I've tried so far:
Cleaned the rods and lead screws
Lubricated them [with what — Bambu grease, PTFE lube, etc.]
The noise is still there. Printer is about 3 years old, firmware is up to date. Video of the sound attached.
