Thanks all for your advice.

I had already a bad steering damper (things were way worse at that time) and I have a bit of play in the steering wheel (a bit to much for my taste) as well as when I have the engine off and I move the steering form left to right it makes a clacking noise (which is the accelerated noise when I drive over bumps due to the shaking).

My suspicion is also the ball joints. It looks like there are still a lot of bushings and original parts from the factory on this car which have never been changed. I thought of just ignore it since I want to sell the car but on the other side, I always hated is previous seller sold me their car with all these issues and I do not want to be in the same situation and want to hand over a car which is in a decent shape and does not require immediate repairs just to be save on the road.
