sway bars are Ridiculously easy. for the front... remove body mounts, remove end links. then replace endlinks (dont reuse) with ones that are the same length as your old ones. Just make sure the sway bar ends are horizontal. the body mounts.. (dont reuse) just have to be the same diameter as the bar you are using. As for the back.. its just 4 bolts into the control arms. I put mine on without even jacking up the car. took about 10 mins.
If your front swaybar mounts are stuck, like mine were, it helps to have a second person there to hold them still while you're under the car with a ratchet. My front took about five hours because the front bolts were such a huge PITA. Like Doc said, the rear is a piece of cake.
