banging noise!!?

[daveh-]

basically, ive had a banging noise from the front of my car, sometimes it sounds like its coming from the left, sometimes it sounds as if its from the right.. and it mostly happens when i seem to steer right, it almost sounds as if its the wishbone bushes, but its not, ive had 2 mechanics look at it on the ram pand neither of them can find anything wrong with it apart from the dogbone bushes, which in my knowledge wouldnt cause the car to make a loud bang when turning right, it would most probably do it if your going forwards and braking or whatever..

just wondering if anyone could help me out,, it seems to be getting worse.. its basically a fairly loud bang and can be heard outside the car also..

thanks guys
