MK3S+ loud rattling noise from extruder

Hi just assembled MK3S+, where is this rattling noise coming from? when I put my hands on the extruder the noise is partially gone.

The not-so sweet sound of dry metal balls

Did you lubricate your linear bearings on X and Y and Z before you installed them?  That sir is the sound of dry balls rattling in their packing oil if you did not pack grease into your linear bearings as part of assembly.

Topic starter answered:
Assembly said no need to put lube...

No, I did not. Because the guide said there's no need to lube, the included lube is for maintenance only...

Step 24: "The printer's package contains a lubricant, which is intended for maintenance. No need to use it now the bearings are lubricated. There is a dedicated online manual on how to clean the printer and apply the lubricant. See help.prusa3d.com/maintenance-tips"
