A cordial greeting to all.
I need your help to determine what is due to the noise of my Golf vehicle A-4 2002.
Well, suddenly it began to sound like a constant typing when the change of third march and the successive ones also passed. I have been told that it may be due to failures of the exchange box as well as the famous boxes, which I ignore that they refer to that, I think they can be in the homosinetic tips or out there. Lift it to the first side to listen to the homosinetic and produce noise when lifting on the other side there is also noise obviously making it walk and passing the marches, the wheels do not present failures of bearings these are fine and without suspicious game.
If you can help me please.
