Here is my two pennorth.......rising and diving suspension- check them
shocks and springs again
Vibration when braking check if you have lost any balance weights and
that no calipers are seized or seizing.
Clunking when turning ,do them ball joints,I saw an LS broke down with
the nearside one collapsed,not a pretty sight.Heavy car sitting on them.
Odd tyre wear,ball joints or tracking???
Rest ...check all suspension bushes,anti roll bar bushes etc.
Hope it's not too scary.....
