Not too bad, I did it by jacking up 1 side and putting it on a jack-stand, The hardest part was getting the nuts off. I had to zip-cut one of them since I rounded it off
It really is as simple as:
1) jack up the car (and support it safely)
2) remove wheel
3) remove 2 nuts (the hardest part as they are probably rusted on) and take old one out
4) put the new one in, tighten 2 nuts
5) put wheel back on
6) lower the car
7) repeat on other side.
