Paul, expect to have to disconnect outer ends of driveshafts, dampers, ARB, and drop the beam down each end in turn to get them out.. unless you are really lucky (and careful!) you really need to disconnect the flexi brake hoses from the body bracket to allow the rear arms to drop enough. Apart from the prop and rear diff mount, you will have effectively removed the whole beam assembly.. 4x4 is worse than 2wd because the springs are an inch longer..
