A4 Roll Bar Droplink

Anyone any advice on removing the roll bar droplink on the front suspension control arm. Mine is the older type with 2 ball joints and I've spent 2 Saturday afternoons trying to get the top ball joint out of the
suspension control arm. I've tried 3 different types of ball joint splitter with no sucess, I'm just reluctant to start removing the suspension arm because I suspect the balljoint on the arm will be as difficult to remove.

Any experiences/ advice?
