The rear axle is less daunting that it looks.
When I did mine, the only issue was the bolts holding the hub to the axle, these are tight, and the nuts rust on. Most of the studs came out with the nut, although one stud refused to come out, but the nut did come off instead. Apart from that one, I replaced all the others with new studs and nuts. An impact driver, if able to get it in there, would be a bonus. Studs and nuts were supplied by Shop4Parts.
It is possible to detach the brake backplates, and hang them up, to avoid brake bleeding, but I removed mine, taking the opportunity to overhaul the brakes at the same time, new cylinders, pipes and hoses.
Jack the back end up, support ahead of the axle pivots on stands. Support the axle and remove the dampers, and the axle will drop to the ground. At that point you can remove the hubs, to reduce the weight of it. Once bare, remove the pivot brackets and drop it to the floor.
