    sounds like a knock. only hear it during idle mostly coming from underneath. Some say these trucks are just noisy in general but this don’t sound right. https://youtu.be/2oq-0Yl42Xs

    Does it get louder when you rev it or put it in gear?

    It sounds fairly normal to me, it seems like all the 4.0l engines in the Tacoma's have a slight tapping noise at idle.
    Mine has since it was pretty much new, usually louder when it's cold.
