I just did mine about a week ago. It is quite easy. For the rears, first thing to do is to lift up the rear of the car and put it on jackstands, you need to lift up the entire rear of the car so there is no tension on the sway bar. Next, there are three bolts at each hub, one is for the sway bar, one is for the shock and the last one connects the hub, you will need to remove all three of these nuts and bolts. Before you pull the bolts out completely, place a jack below the lower control arm (just inside the hub), so when the bolts are removed you have something holding the tension that can be controlled and lowered to release tension. Sorry about the bad grammar, but it is late at night
Hope this helps.
