I have this exact same problem on my passenger side. I have replaced both ball joints, top mounts, driveshafts and all engine mounts recently. The only things left are wishbone bushes and track rod ends?!
Strange, just like a knocking/clunking noise when lightly launching and lightly braking, all when doing slowing speeds and manoeuvring etc.
It is definately nothing obvious like wheel bolts etc etc etc, had the whole front end apart recently and eradicated lots of little problems, but this small but slightly annoying one is still here. Oh and all brake caliper bolts are tight.
