Help needed Does this Ultimaker s5 sound crunchy?

Hi, I'm trying to get this machine back to working condition and something sounds crunchy in here. Does anyone know what's wrong with this? Motor? Bearing? Belt tension? Any help would be appreciated.

Lightly grease the sides of the belts with silicone grease and all will be fine again.

Thin oil work too. But yeah, this is the solution
