Annoying Creaking Noise

[Luke Surrey]

I'm having a creaking/knocking noice that seems to be coming from the passenger side door area. It hard to explain but it sounds like when you open the door and the plastic hinge mechanism inm the middle that stops the door opening too wide..it sounds like this as it engages are various stages of its travel when you open the door. I've tried greasing that part but no joy. The noice appears when you are mostly going slow and you turn the wheel and the weight of the car shifts. So if you're going slowly right and then turn the wheel left. Could be panels creaking where they are joined underneath?. My wife also has a Zetec S and she has the same noise although its very intermittent and not half as annoying as my car. Does anybody else have a similar issue. Its nothing to do with the bottom ball joint etc as I've checked those for play.

I've played with other things like the back seats but I'm sure the noise is coming from the passenger footwell door area. I've shaken the front seat, the door but I can't replicate the noise unless I drive like described above. Its got worse in the last couple of months possibly becuase its dry?. Anybody had problems with shocks creaking?

Hope somebody can help!
