Hi guys, I've got an EL 6 and the car makes a knocking sound from the front left every time I turn the wheel from right to left. I was thinking maybe a worn shock, the front left tyre is worn around the outside edge, which might be because of the problem. What could be wrong?

You'll need to check the whole front end, strut bar bushes, upper control arm bushes, b/joints, rack ends, tie rod ends, the list goes on.
