any ideas on a suspension clunk, usually while backing out of parking space

I’m hearing a slight suspension “clunk” coming from the front left side whenever I back out of my garage parking space. It almost always happens when I have the brakes slightly pressed and turn the wheel to the left while backing up - and then sometimes again when I unwind the wheel.

I tried to take it to the dealer to have it checked out, but we couldn’t reproduce it when parallel parking.

Has anyone ever had a similar experience, any ideas where to look?
