Gear box can be a bit of a mission for one person being very rear heavy, gearbox jack would help alot if ur by yourself
The nuts that bolt the engine mounts the the engine frame can be quite tediouse as there isn't much finger room to thread them in
Front shafts aren't too hard, most difficult part would be getting the splined part of the shaft through the hub as you'll need to pull the hub out to make room to slide it in... then there's 6 bolts on the passenger side which are pretty easy to do if the vehicle is jacked up
