Because it’s a very small movement of the steering column that affects it.
You should feel some very small free play of the steering wheel in the straight ahead position.
I’ve been there, even in old bombs with worn recirculating ball steering that had much free play.

I had this problem on a Xantia - turned out to be a very small amount of play in a track rod end. Trouble was if you you jacked it up the play went away! Try rocking the wheels 9 o'clock to 3 o'clock with it on the floor, if there is any play you will be able to feel / hear it.

I cannot feel any play in the steering wheel. I have tried today and it seems good.

The suspenstion and direction was checked with the car on the floor, the mechanic has a trench in the middle of the floor for getting under it. He have found nothing wrong this time (last time there was a worn anti-roll bar link and I had it replaced).

When rocking the wheel at 9 and 3 on the ground, it would immediatly move the steering wheel so I could not feel any play. Tried with both front wheels.

I would say that the only confirmed issue at this time is the left hand driveshaft that has some play, my logic would be to follow that one. Also, at this time I think I need to set a hard spending limit to fix this as it might get really expensive realy fast on a 18 years old car. Also, the fact that I like this car a lot does not help :)

I went to an independent garage today with this issue and they sent me this one. It's a 40 euro fix, including labor, for a Lemforder ball joint. They stated that no other issues have been detected.

So I got good news and I got bad news.

Went to the highway to test the car after the ball joint replacement and it's definitely better but the problems is not 100% fixed. Yet.
What has improved: I can now drive at 120km/h without major shaking which is an improvement and, generally speaking, the steering wheel does not shake that much even at 130km/h.

What's bad: The geometry allingment is bad I would say because when the car goes straigt, the steering wheel is a bit to the left. That's not horrible but I have asked them if an alignement is needed and they said no. Obviously, it is needed.

At 130km/h it it seems the remaining shaking is more from the chassis and less from the front wheels, so I would probably replace the rear disks and pads as soon as possible.

Wonderful to see a Lemförder ball joint put in for €60. :)

Work on the front end often affects the steering centring.
Try swapping the front tyres around.
I have variations of steering centring as the tyres wear down.

I’ve had shaking from the rear at 130 km/h caused by tyre imbalance.
The rear discs and pads do nothing at 130 km/h unless you apply the brakes.

The actual number is 44 Euro, all included. Yes, the parts and labor are a bit cheaper here in Romania, but also keep in mind our wages are lower.

Already did swap the front and rear wheels.

After I replaced the front disks and pads there was some improvement and the rear discs are just horrible. Also, the braking was way better after the front disks and pads were replaced.

I had an alignment done on the car - 16 euro all included (as it seems local pricing is interesting for some :) ) and I can say we have some results.

At 130km/h, there are still some vibrations but they are well less noticeable and I think I am on the right path. I can do 120km/h now almost without issues so, for the moment it's acceptable.

I will still do brakes and pads on the rear and the the accessory belt (hope this is the proper name) for safety reasons and I hope there will be some improvements on the vibrations. I am not sure where I will go from here, I'll see.
