I just got this off of Facebook marketplace and I am not sure the year of the model but it’s the artisan style mixer. I feel like this sound is not right but I don’t know how to explain it.

I tried looking stuff up and people said common issues are the grease or gears. Is this something I should worry about? Do I need to bring it in somewhere? Or am I losing my mind and this is completely normal
