The cause of the fiddle when turning the steering wheel is one of the springs, the panting about other details. The solution of the problem is to process the scrawny parts with a small number of persistent grease (e.g. the lithomar).
Access to the cowardly spring can be obtained through the tilt control panel of the steering column. It is best to use a thin object with small amounts of lubricant. During lubrication time, it is necessary to periodically rotate the steering wheel on both sides to balance the lubricant.
