Default Front Clunk when braking, accelerating and turning

Hi all, trying to diagnose a clunk that happens pretty much during any transition the car makes. A shop took a quick look and thinks it's the steering rack, but when I jacked the car up, there is no leaking and no play in the wheels when I try to shake them. With the front in the air, neither wheel has play and quickly wiggling the swing arm links, tie rods, etc didn't show play either. Thoughts?

The car is a 2003 with 103k miles. Service 1 and 2 are done. Anyone have ideas. I need to take the skid plates off and check for loose bolts I guess. Any feedback is appreciated!

Are you able to point out where it's coming from when you brake? Like front left or right? Is it like a metal on metal clunk or something light/heavy clunking

Did they look at bushings and the shock towers?

I'd start with checking your FCABs. When they blow out you'll feel clunks up front when coming to a stop and accelerating. Attached was my original FCAB that's completely torn apart.
