Diagnosing chassis noises on the internet is like diagnosing itchy bollocks. Could be crabs, chlamydia, gonorrhoea, wearing the same skidded pants for 3 weeks, crotch rot, thrush, anything.....
Probably wise to start with the most expensive component first, the rack. Get it on ramps, put it on full lock, climb underneath and grab the fully extended tie rod and give it a very firm tug (like the aforementioned body parts). If you can feel even the slightest amount of play, that will be a source of the noise. A little wear is fine so long as it's not affecting the handling, and you can tolerate the noise.
But I suspect on yours, you will be wanting to examine the rear wishbone bushes, aka 'console bushes'. Any pronounced twitching of the steering wheel and clonking is usually the road wheels moving around of their own free will......which is normally bushes, shot dampers, shot wheel bearings, shot tie rods etc etc.
