I been hearing these high pitched clicking noises when driving over uneven roads (even the slightest imperfections). Almost sounds like someone is tapping on an empty aluminum can of soda.

So while I was changing my oil today, i started applying pressure on my bumper in an attempt to replicate, and locate the source. So i started to hear different squeaking noises from the strut location, but I'm unsure if its produced by the shock mount, or other parts.

I already have ball joints, and outer tie rods, but I would like to make sure thats there aren't other issues, so I can address them at once.
