I have a ford focus 1.4L from 2009 and it has hard driven 120000km made by me. These last 20-30k the clutch is well put it this way, not new. I wanted to change the clutch but before that i wanted to ask you if this space in the differential is normal (video bellow). I hate it when you start or when you let go the throttle there is like clunking and you feel like you drive a bus. You know those old buses where the differential is so worn out that when it slows down as it burns unburned fuel it rocks the bus. I dont know how to explain it english is not my native language. If you have any idea what can make that much space in the transmission. I feel that is why the car is rocking lets say 2 times when you let go the throttle in gear or the first time when i start, the clutch bits and you can feel the diff turn. Please watch the whole video.

 

No one seems to know what the problem is I thought a lot of people have this problem. By now I seem to found the name of it. driveline shunt
