You’re sort of like, “hmm, I don’t recall this car ever soaking up bumps without any sound at all”. I just checked my log, I replaced mine at 99k miles. I’m at 136k now and it’s still good. Hyundai had the same issue with couplers crumbling. Unlike Toyota they issued a TSB with an improved coupler and that is the coupler I used on my car.

I really think the accumulation of driving I do on the city roads I drive on is harder on the suspension/steering than a track day or the rally-x I do. Although the rally-x is pretty tough.
It is interesting that nearly every post I see of busted couplers is on a 2013 model, but who knows.
Either way, if the sound doesn't go away next time I swap suspensions I'll have a pretty good idea of what to do next. Gonna grab one of those Hyundai couplers in the meantime. Thank you for the DIY and figuring it all out.
