The car has started to loose it's Italian spirit and feels like a Volvo 240 at speeds from 60-100 kmh (40-60 mph). The Stilo changes direction slightly when trying to go straight ahead and I have to constantly correct it with the steering wheel, just slightly. Is this a symptom of the rear bushes being worn? There is no oil back there, but when using a crowbar at the axle near the bush, it's a bit flexible.

I have new bearings at the rear, but not at the front. New wishbones at the front though, but not the track rod ends. But everything seems in order at the front.

Any thoughts?

Bear in mind the Stilo does have an element of 'self-steer' at the rear. How are your dampers?

if the bushes are worn you will get a clunking going over bumps.
I would more suspect worn track rods, wishbones, tracking or droplinks. Droplinks on their own make the world of difference to sharpening up the suspension.
Worn track rod ends will also give the loosy goosy feel.

Have you had a 4 wheel tracking check? this as well sets the geometry up correctly on the car, i do mine once every 6 months or so as it does tend to wander on the stilos.

Mine does that at 80mph but this is down to wheel alignment with me. How is your front tyres wearing?

Dampers and springs seems fine. No bouncing. They are also part of the Eibach kit. Earlier, it seemed like the rear helped oversteer at high speed, but not anymore.

There are some clunks when going over speed bumps, or more like small "bangs", not being speed-dependent.

The wishbones were changed a year ago, and Fiat genuine. They seem perfect.

Now I do have a couple of track-rod ends laying around, but the droplinks are 3 years old. Maybe I'll start with these 4 items, as they are muuuuch cheaper, and possible to do at home.

Not done a 4-wheel align for ages. The car doesn't pull and have perfect tire wear.

Thanks.

Front tires are dead flat on wear. Both sets... (215/17 summer and 195/15 winter).
