Hi, my polo has been making this noise for quite a while now but never bothered to do anything about it, it was only last week that it started getting louder, every time I turn left or right o have a clicking noise, I think it's coming from the N/S so I changed the cv joint, bottom ball joints both sides, drop links but it's still there, I'm just chucking money at it now and it's getting annoying, my next guess would be top mounts but thought I'd come here first to get a answer. Thanks 

doubt its top mounts - id spend some more time checking for free play in the other joints

 

maybe drive around an empty car park while a helper listens  

When I jacked it up and did a side to side theres no play what so ever.
