+1 on both counts. 
If you need a complete banana arm don't get it from Nissan as it will cost you a small fortune and that's before it's even fitted. Try a PM to a trader on here called zmanalex. 
If you just need the bushes then you could try Horsham Developments for them; http://www.h-dev.co....oducts_id=25342 
Best fitted in pairs or you could try up-rated items which is what I have; http://www.h-dev.co....oducts_id=25451 
  
Hope you enjoy your Zed.  
 
  
I'm hoping they'll have a look at it under warranty tbh. If not then thanks for pointing me in the right direction  
 
  
If it is the ball joint on the banana bar then it's notoriously difficult to diagnose so they may try to fob you off
