Hi, I have a 2004 4Runner and seem to get a rattling type sound only when the engine is cold and usually after straightening out after a slight turn. Any ideas? The sound doesn’t last long (You may need to turn the volume up to hear it in the video) thanks!

I can hear the rattle slightly, but nothing comes to mind since you said it only does it when cold.
