Rover owners: metallic twangy sound

hi all, i've mentioned this before but previously i thought it was abs related, now i'm not so sure... bear with me whilst i try to explain the symptoms. sorry for the long post.

when i brake gently at low speeds (under 20mph) whilst turning the wheel, there is sometimes a repetitive twangy sound, a bit like someone repeatedly twanging a metal ruler with a sort of added clunk. i think it only happens when the wheel is turning to the left (not when i turn right) and i'm also lightly braking; it's not every time but mostly, and it doesn't happen when i brake hard.

there is also sometimes a tick tick tick sound that happens when i am turning left without braking that bears a striking resemblance to the twang sound, only more muted, with the same rhythm at least.

as there is a little feedback through the brake pedal when it happens i had thought it was abs related, but all the reluctor rings are fine and there is no abs light on on the dash. i've also just had all the pads replaced where it was found that the inner pads had jammed in the callipers - they're all ok now though.

i have 2 outstanding recalls which are being looked at in October:

Quote:

In an isolated number of cases, it is possible that the lower suspension swivel/ball joint mounting rivets can become detached. This may in extreme cases, if not identified, result in a possible detachment of the joint.

Quote:

Under extreme conditions it is possible that the rear suspension top arm may fail.

is it possible that either of these may be causing my symptoms?

i also noticed that there is a rubber joint/knuckle near the suspension coil on the drivers side, which has split. it is the one in this image (not my picture), could this be related to the noise/recalls/symptoms?
