I have the same issue. I start hearing clunking noise after I got new suspensions.
Noise only occurs under 30mph on light-heavy bumpy surfaces.
I just got a set of UUC RTAB for below $65. Will have them installed next week.
FYI, I changed the RSMs but clunking noise remains. I know one of my Rear Sway bar links is slightly bent since years ago, but I never bothered to change them. I will do the RTABs first and let you know the result. And These bushings including Subframe bushings are not easy to inspect unless you actually take them apart, then you might see some cracks on them.
