Steering 'rough' when stopped/very low speeds

Hi,

Just a quick one. When I am stationary or going very slow (usually in a car park) the steering makes a bit of a 'rough' noise when steering is applied. Like something is very dry.

Any Ideas?

Thanks,

Steve.
 
Been a few posts about this and mine is the same. Lower ball joints I think. Mine is on full lock on the right, quite loud. I've enquired about this at RS myself.
