Cheers for the fast reply Andrew. I had no issues with the bolts so that was good. It was only when I got to lowering the subframe down that I realised that the shaft didn't come away from the diff. Turns out its just a pain and needs a firm clout to the side a few times and it'll just drop off. For future reference there is no internal spline for it to catch on, its just two facing plates behind the cv joint.
