Open the door to the car, now use your hands and push up against the inside of the door jamb to rock the car side to side and see if you can reproduce the sound.

If you can then it can EASILY be found since you could just have one person under the car and another person rocking the car. Use a mechanics stethoscope to narrow it down if it's echoing.

 

Doesnt work we have had 4 people one on each door of the car and cannot reproduce the sound we have had the car off the ground and have hit the tires with a sledge hammer and cannot reproduce the sound it ONLY happens when u hit the brakes or a bump with full car weight while driving!

 

Will it make that sound if you go over a speedbump WITHOUT using the brakes? Might not be suspension related at all, might be all in the brakes.

 

the sound happens ANYTIME you hit a bump while braking or not braking I even pulled callipers and pins 're greased them checked calipers mounts and pads rotors are new 10k maybe ago it seems like anytime the suspension is jarred whether its a dip from a crack or a bump it clunks its also louder on driver side even happens when 1 wheel hits a bump or both! Doesnt matter which side both sides have same clunk just louder on one side!

 

Check the bushings in your control arms. Also make sure the 3 bolts holding your shocks arent loose.

 

I'm not sure what to suggest at this point, there's only so many moving parts on the front suspension. Are you SURE you have replaced them all?

-Sway bar end links
-Front upper control arm
-Compression rod
-Transverse link (the other one at the bottom near the compression rod)
-Struts
-Wheel bearings

The next thing to look into would be steering related, inner and outer tie rod ends on both sides. Also check for a cracked front subframe brace, it is prone to rusting and it might be broken and only makes the noise when the chassis flexes, here's what it looks like.
