How to replace a broken vibration motor?

Some time ago I noticed the vibrations of the phone being kind of strange like the vibration motor was loose inside the phone or something. The vibrations rattled even in my hands. Now, however, the vibration is gone entirely. Even when I test the vibrations in the diagnostics panel, I get nothing.

I live in a region where Samsung certified repair shops are in limited numbers. There's only one in my city and they told me that they are not sure if it can be fixed. Is there something I can do to fix it or do I just have to live with it?

Thanks!
