Hello
, then in this Hyundai and in most of the 2008 model vehicles onwards the trend is to equip electrically assisted address. The system is extremely easy and effective, I have never scocked that due to some special defect in Hyundai of manufacturing, a fault originates, noise ...
The principle of operation is basically an axis (without end) engaged to the pipe of the address, this Asu Ves has a torration bar with two optical sensors (in this case) these sensors what they do is send to the "EPS" that is the module that controls the safety. A comparative signal that indicates where the left or right torcion is being carried out, already having clear the EPS, sends a signal to an engine that is the drive and responsible for a direction, soft stable and with a lot of comfort.
When it produces sound, it is simply that the friction and gear of the driving motor and the endless axis are dry, what you have to do is apply fat to where it indicates the level indicated.
luck:
