How did you get on?
I've got to get under the front end again tomorrow because yet another annoying and infrequent knock has appeared!
I have replaced the following, bananas, lower arms, all cone bushes associated with, drop links. Now its fairly smooth except when at a snails pace over say a speed bump when I get a loud knock that sounds like your slapping two plastic chopping boards together.
Damn annoying
Drives fine otherwise, alignment is spot on, no uneven tyre wear.
Only things left to look at are the hub carriers, arb bushes (unlikely),shocks and checking all bolts are torqued up correctly.
