Funny noises

Hi all newbie here 
had the car for a few weeks now and its got a strange buzzing noise at 20mph-110mph don't know if its there after that but i would think so, the noise does not increase only the pitch, at 40 mph its worse because something is resonating
it only happens on left corners or any left steer even in a straight line road camber can bring the noise on gentle left/right (swaying) steer does too.
i'll try to describe the noise 
70 mph on a motorway and start to gently sway the car
turn the wheel to the right its smooth steer to the left its like driving on the M180 (noisy bit) steer right its smooth and so on, for those who aint drove on the M180 its a bit like the motorway rumble strips but not as bad.
I have changed the NS wishbone as the ball joint had some play,
all bushes seem fine the only thing i can find thats not upto scratch is the off side steering spindle giving it a vigorous shake/pull/push/twist reveals nothing but start the car up and have someone rock the steering and theres a clicking movement felt through the arm. its not the rod end, maybe the ball joint further investigation needed.
would this cause the noise described
car is a
1997 cosworth estate
160,000 miles
new discs & pads all round
wheel bearings are all ok
i have changed the wheels round but made no difference.
Cheers guys
Andy

You say the wheel bearings are ok but I think this is the cause, they don't neccesarily show movement doing the usual checks, is it comming from the front or the rear of the car cos the rears are more prone to wear and the noise you describe sounds like it did when my rear bearings went.

Hi pete
 with you thats a wheel bearing sound but
OSR wheel bearing was changed 18 months ago
i did the usual pull/push/spin check + I used leverage this is when i found the ball joint movement.
wife drove the car and i crawled around the car feelig and listening only thing i found was that the noise is from the front, I also found 2 legs but they wern't mine

I had 3 bearings, (allbeit not oem bearings) fitted in as many months and they were all shot, I ended up buying s/h complete hubs from madmanscorpioman and fitted them, problem cured
could be your front ones, they are more awkward to do...

Regarding the clicking movement felt through the track rod.
Grab the rod & give it a sharp yank. If you feel a click where it goes into the rack then it sounds like the ball joint has worn.
If this is the case, then I'd get it looked at pronto as it could be very dangerous

ball and socket joint on the other end of your track control arm may be worn .....worth sliding the sleeve back and checking for movement .....?
