Car makes noise in only in park or neutral.

What is your question?

Hello, I have a 2000 Lexus ES300 with 347k kilometers. When I am in park or neutral at idle, it sounds like someone is dragging a chair on a smooth floor under my hood. The sound is not loud but still noticeable. The car still runs great and shifts smoothly but the sound is still concerning. Any advice is greatly appreciated, thank you.

What makes this problem better or worse?

Happens only in Park or Neutral

How long has your 2000 Lexus ES300 had this problem?

A few months
