front end knock

i posted earlier about ball joints knocking so ive replaced both wishbones both drop links and both suspension arms (look like small droplinks). i did the pass side first and the knocks from that side dissappeared, however ive just done drivers side and the knock is still there on that side. if you take the wheel off it doesnt make the noise when the steering is rocked. anyone any ideas. the ball joints on the floating hub look ok, no splits. cheers for any ideas.
 
cheers for the advice turkie172. bit of an update. it turns out it was the steering rack bolt on the pass side not tightened enough. previous owner had the exhaust flexis repaired before i bought it. mechanic must not have tightened it back up enough.
