Default Also popping noise, spent money, no fix

Hi, my GS has 225,000KM on it and an annoying noise is making think to sell the car. It's been going on for a couple years actually, getting worse and worse. Under braking while going over tar-strips, bumps, potholes, I hear a pop-pop, popping noise from under the car. Last week I replaced rotors and pads (Brembo and Akebono) and lower control arms and ball-joints (Moog) and had a 4-wheel alignment. The noise mostly went a away, but returned after a few days. Sometimes I think front stabilizer links, other days it seems like rear suspension, and other days like the doors are clunking against the body. Any suggestions? Thanks

I get a clunking sound under these same conditions! No idea what it is, not willing to sell my car over it.

check the upper control arms and the stabilizer links and mount bushings.
also check the steering rack bushings and the caster arm bushings!

Let's see, UCAs are 3-years old, caster arms are 2-years old, Rack bushings are Daizen, 3.5 years old. Stabilizers and mount bushings to check, OK will do thanks!

I've having the same issue and everything on my car is new. Only thing is it goes away when it rains.

My clunking noise went away for good after I replaced my transmission and motor mounts.

That was my thought, which is why I am waiting to replace those parts when I drop the 2JZGTE in this girl.

I believe that's OP's culprit. The liquid filled mounts have probably separated and dried out causing clunks.

How about your struts? These could also be a culprit.
