I'll go through the whole process of trying to solve this problem.
The model is 2004. 2.2i with 225/45 17" wheels.
1. First of all, I had some sound when going over speed bumps and my mechanic saw that the sound came from bad front control arm bushings that were really bad. That was the only thing that was changed. After that, wheel started to vibrate at small speed like 90kmh.
No vibration before with s**t tires and bushings.
2. After that, I checked the tires and they were bad as well, 2013. Michelins.
3. Okay, so new 4 Hankook tires will sort that out? No... They also checked my rims and saw that rears were bent a little so they fixed that.
4. After all that, I replaced front control arms with new bushings, front discs and pads and then did the wheel alignment.
Result -> Still has small vibration, but a lot less and at about 130kmh (80-85mph).
I did 220kmh at one moment and had no vibration but maybe I was just holding my steering wheel strong.
The way I tested the vibration was setting the cruise control to 130kmh on an empty highway and vibration changed. It was changing depending on the road quality and sometimes when changing lanes it even disappeared.
Maybe it is just normal to have that when everything is new and then you feel every single thing on the steering wheel?
Or am I wrong about that?
Thank you for suggestions and answers.
