2011 WRX Knocking Sounds!

Jeff Cj · 10-22-2020, 10:01 AM

Hello everyone, I’ve noticed recently that my 2011 WRX has a little knocking sound coming from the passenger side. (It’s lightly modded with about 160k on it) I’ve tried to use other threads to diagnose what could be causing it but I haven’t figured it out. A lot of people talk about “regular Subaru noises” but I’m not sure what that means.

Any and all help is greatly appreciated!

Here’s a video showing what side and the knocking sound

Never loads, never gets past a spinning circle.

IMO, linking a video uploaded to YouTube is the simplest way to post a video here.

If you hold the RPM's around 3k, does the sound speed up and follow?

I watched the video, I can't really tell where the sound is coming from in the engine bay. I also have a 2011 WRX and had a knocking sound on the passenger side, it turned out to be the downpipe bracket hitting the frame. It sounded more high pitched than this however...
