I suspect it's your dampers knocking.

With the bonnet up, one side at a time, bounce the front of the car with one hand on the strut top. If you can feel it through the strut top, it's the damper.

If it is the dampers, the knocking will normally go away or quieten down when the car hasn't been used and the weather is cold. I'd expect this is due to the oil in the dampers being thicker at these times.

As soon as the weather warms up or you use the car for a few miles and the oil warms up, the knocking will return.

It could be the gas struts inside the shocker housing. Mine knocked at slow speeds so i pulled the strut out and found onside dry and the other side full of water.

cleaned and refilled with greased now its silent

Hi Tony
i had the same problem on my evo 9 at the front wheel,
took it to my local tyre garage and they couldn't find anything wrong any part suspension system.
So my mate who is a mobile mechanic came round and found the problem straight away,
its a 2 man job,
you need one person to lift the up the wheel arch and the other person to put there fingers around the bottom of the spring where it sits in the dish, and remove all the loose bits of GRAVEL,
the noise is when the spring is sitting on a bit of gravel and then you go over a bump and it dislodges the gravel causing your spring to hit the bottom of the dish,
hope this helps and solves your problem,
it solved mine and no more knocking.
regards steve

Was the car cold? I.e. not been used all day?
If so, knocking dampers may not be so obvious...
