I've decided to share the information about the change of the complex switch (the arm of the indicators and the wipers) with the forum users. By the way the bearing can be changed; when it is worn out, it causes the shaking of the steering wheel while braking at higher speed. The instruction treats a car without air bag. Before disassembly of the switch, it's necessary to take out the plastic case of the ignition (I've not taken any pictures of this step).
Take the button of the toot out, unsrew the lid and take out the steering wheel.
Unplug the plug from the left...
...and later on the right.
Pull out the upper fixing element.
...and later the bottom one.
Turn the switch a bit right, pull it towards ourselves.
The placing of the bearing.
We push the two fixing element and push the bearing.
