I did it last year and I'm practically an idiot. Here are some tips:
You'll need a 36mm socket with a length of pipe over the ratchet handle to get the leverage to break the wheel nut. Make sure you put the little washer back in correctly after assembly, I believe the curved side points outward. You'll need to support both sides of the rear end with jackstands so you can rotate the axle for access to the three torx bolts. The torx bolts are deep inside the hub, it goes way back like a tooth, you need a long skinny extension to reach them, but they are all reachable by rotating the axle to gain access to each one. Getting the torx bolts back in again is a real pain, basically you either sit there for eight hours poking away with the bolt while hoping that the hub stays together long enough to maintain the hole's integrity or you tape the hub together like I did and get underneath your car to see what you're doing. MAKE SURE YOUR JACKSTANDS ARE SECURE BEFORE GETTING UNDER YOUR CAR.
It's not really that difficult, but it can be frustrating. Good luck.
