Hi, just noticed an intermittent knocking while driving over uneven surfaces. I think it's coming from the steering because when I stop the car, and give the st/wheel a bit of a turn, I hear the same noise when I release the wheel - notably only when I release hold of it. It seems to be below and up front. There is a bit of play in the st/wheel also which I'm not sure should be there. It's not the suspension, I had new wishbones and bushes done in october. Anyone know of this problem? Thanks
