I've sold the car and new owner has replaced original steering fluid with thicker and problem solved.
The steering wheel is by rotation for more than 180° difrently soft to rotate. The shaking of steering wheel on video ist resault from moving it from left to right while rotating for 180°. If you had similar problem please leave comment below. Thanks
