Left side "clunk" noise during heavy cornering + low speed bump

I need help diagnosing a "clunk"/loose metal noise on the left/driver side.

It's present during these situations:

1. Whenever I hit a moderate bump on my front left wheel during hard cornering to the right -- and only right. Like when I'm going on an on-ramp.

2. At moderate speed when I go over large bumps in the road like one of the larger protruding lane reflectors on the road.

My car is at 70k and have just replaced both lower thrust/control arms (with M3 arms), sway bar links, struts + shocks (Bilstein B6 on Dinan springs) and tie rods. The noise was present BEFORE all the replacements and is still present after.

Could it be a sway bar bushing? Steering? It's not something that arises frequently but it does rear its head during more spirited driving ... which really take away from the experience.

Thanks

This is just omnipresent with our steering racks, very common. I have it too.

I've got this too. I started to notice within the last couple of months. 35k miles.
