There is a ball joint on the other side of the forward control arms also people have reported an inconsistent clunk from those very bushings when the bolt works itself loose or when the bolt was tightened before loading the springs.

I would first try to video the wheel while braking to see if there is motion. A pry bar is nothing compared to 5000# slamming into that bushing.

Then even if you can’t verify motion, with the Wheels on the ground loosing and torque those tension strut bushing bolts and for good measure the other side as well.

There are about six ball joints on each front wheel and any one can cause a chunk. Try to determine if any has broken its seal. Any sign of leaking oil and it’s likely the clunker
