Hub assembly threads ???

Daft one , recently on my ph1 track car , slight vibration on really hard cornering ?? Like the wheel was loose ?? Tried new track rod ends , wheel bearings ? Drive shafts ?? Still there . As far as I can work out the threads on the hub assembly is worn and the nuts come loose under hard cornering , like track days etc . I've spoken to a mate , who runs s garage and says its as rare as donkey doo , unless the wheel bearings is bolloxed really bad etc , any one else ever had this problem , as its s new one on me , and strikes me as odd
 
Cv joint bottoming out ? Never heard of that one either tbh , gonna get her up in my ramp for a better inspection , thanks for the advice Dan ,
 
It's quite common on these with a lot of neg camber and worn wishbone bushes. The wheel moves in under hard cornering and the cv joint runs out of travel. You won't find it on a ramp, I've only managed to find it by lots of measuring!
