200k suspension maintenance

Hey everyone!

Happy to report that my 09' has just clicked 200k miles and is still running great! Other than basic maintenance it's been pretty hassle free during the time I've owned it.

That said I'm looking to diagnose a 'clunk' coming from the left rear of the car. It's most noticeable when you drive over a slightly bumpy road. Almost sounds like the exhaust is knocking against the side of the frame (its not this, I've checked that much) -or- a worn out control arm bushing with no rubber left - Noise only occurs when driving over tiny bumps in road, not during acceleration, breaking, or cornering.

I've pulled up the rear suspension on real OEM:

I haven't had the car up on a rack to fully locate the source of the knock, but my gut is telling me it's worn out bushings, probably the lower control arm? Any of you have similar issues or any issues with worn out bushings? In a perfect world I'd replace them all, but for now just looking to tackle the most necessary.

Thanks,
Ryan
