Managed to get everything loose apart from the top 17mm bolts attaching the carrier that are recessed.Yes it is tight, however if you can get the drive shaft joint far enough back then you will get in but you may find then you require a slim line socket.
In this instance I would advise you just to disconnect the drive shaft from the diff. which should only take you minutes, it is a flat flange so you will not lose any diff fluid.
Now you will find that the drive shaft will slide far enough from the hub to get the last bolt out.
Refit the 4 bolts by around 6 threads and gently tap the heads of the bolts
uniformly so that it comes out square.
