If it's a constant multiple clicking noise on turning and pulling away it will be a cv joint
If you slowly accelerate from 50 to 60mph does your steering have slight wobble??
If it's a single knock when turning slowly it will be a bush in the wishbone if it is a few knocks together on rougher roads or of there is a dip etc in rd surface it will be drop links (drop links are common faliure and usually when knackered you can't get em off they have to be cut off
