2020 GMC Yukon — single clunk over small sharp bumps

There is one front-end clunk over pothole edges and driveway lips, but larger smooth bumps do not reproduce it. How would you isolate end links, strut mounts, control-arm bushings and ball joints? I would rather test this logically than replace parts. What would you check next?

I'd keep this practical. Verify the cheap/easy branch on the 2020 GMC Yukon before a big repair or a big spend. That's where I'd start. This is from a 2020 GMC Yukon in Dallas. I'd want a dollar figure or a measured spec, not 'should be fine.' Worth doing even if the car feels fine right now. This is me being the wet blanket on purpose.
