Find a just bumpy enough section of road where you can be absolutely sure it will produce (and reproduce) that symptom. Better if it’s a secure or secluded area.
Settle on a safe speed that you can safely repeat, and try passing over the rough patch of road maintaining a steady speed, but no brakes and just enough throttle to hold a steady MPH.
Note the sound, . . . then pass over the same spot (@ the same speed) but moderately applying brakes and gas together to maintain your speed, and then determine if the symptom has gotten louder, or quieter, or gone away, try it a few times in an A/B comparison test.
Driving like this “gas/brake/loaded” will take up slack in ball joints, radius arm bushings, brake caliper slider pins, drive shaft running gear, but not so much in the steering control parts and chassis pieces along for the ride.
If there’s no change, go into that section of road a bit faster and just apply brakes while passing over that spot dropping your speed to listen for a difference.
Understand that it may not be in your suspension but a loose part somewhere else.
