Hi All
I'm having the same problem on a Mk2 2005 Focus I've picked up recently.
Just an irritating knocking noise at low speeds on the RHS of the car, can't tell whether it's coming from front or back which is annoying but i'm inclined to say front.
Can someone point me towards this part on eBay that you refer to? I'm a bit of a noob when it comes to car repairs!
Thanks!
