Help! Can't figure out this front end clunk over bumps.

Hey YarisWorld!

First post, did some searching on the subject but couldn't really find the answer to my question.

My GF has a 2007 Yaris S Sedan, bone stock. 109,000miles. AT

The past few months it started to develop a clunk noise at low speeds over bumps. It's getting worse now and I can't figure out where it's coming from. I was just out under the car grabbing, shaking, wiggling everything i could grab to see if anything was obviously loose. Nothing budged. Tie rods looked good, no loose bolts or nuts on the control arms, nothing. Only thing I did notice, were the sway bar end links seemed to pivot in place on their joints. Is this normal? I can grab the end links and turn them by hand and they pivot back and forth. Also, I noticed the strut tower looked different when the car is jacked up, as opposed to on the ground, is this normal? I'll attach a picture. Any help is greatly appreciated.
