Hi all, hope someone can help...

I have a rumbling/knocking sound coming from the front nearside wheel on my mk II focus. It's loudest when going fast, and much louder when turning right. Hardly any noise when turning left. Going round roundabouts, for example, it gets louder as I'm going round, then gets quieter as I turn off. Going in a straight line it's there but not as loud. There is a slight judder associated with it coming through the steering wheel.

When stopped I have had it on full lock going round in circles and again I can hear it when turning right but it's much softer than when I'm travelling at speed. Going over bumps doesn't make it louder.

I can't see anything obviously wrong with the car when I've had a gander but then again I don't have any clue what to look for to diagnose this. I'm guessing CV or similar...?

Any thoughts? Any help would be really appreciated... Thanks in advance.
