A frame removed , lower bushes are fine and the rear bushes look and feel ok. Cleaned the paint of the frame and cannot see any defects. The only thing I can see is the handbrake cable runs over the frame and has worn through the outer pvc and worn the metal inner part, there is a corresponding indentation on the A frame. Fingers crossed this is it. Going to get some new bushes and repaint first so will report back. Thanks for the replies and Jonathan your mail box is full. Baz
