Clunk/knock, starting to get concerned.

Have you checked the ball joints?

Dropped it at a suspension specialist, the only parts unchanged are the upper and lower ball joints, and the upper bushes. Will see

I also gave the driveshaft right before the bearing a good vertical nudge, there is some slight play in it, but I do not think that thats enough to make the noise im hearing

On the rear of each frame rail - at the very end right behind the bumper, there are some loose swinging weights - you can see them if you just look under the rear bumper. Quite heavy. For resonance dampening or some such thing. Wondering if you are hearing those hit the bumper/frame when you do something quick/sudden that might get them swinging in just the right way.

Hello

Any idea how these things look like? I sat under the car for ten minutes looking forward towards where the chassis meets the front bumper...couldnt find such a thing...

Rear bumper.

Rear bumper.

Just checked them. They move normally and no...the sound is from the front.

Also the specialist says ball joints and upper bushes are fine.

Thinks that the car has some loose panels up front from a previous collision (which it did have a bad collision) that are being torqued once the suspension is torqued.

I really do not know what to do now

Not sure about body panels. Motor mounts maybe? Ever notice a thud or jolt when putting into gear? Maybe have someone put it from park into gear while you watch the motor for any movement.

Changed those to new originals, no thud or vibration when putting into gear

Turned out to be loose body mounts...

Body mounts? Like the bolts that hold the body onto the frame??!

Yup

The rubber bushes had been compressed. Indy packed them and retightened. All solid now
