I would say the rears are a little easier than the fronts, since the suspension is a little simpler, and especially since you already have the experience on the fronts. Since your car is only four years old, hopefully you won't have problems getting the rear LCA bolts out. I had to get mine drilled out at a shop and have new bushings pressed in at the same time. Broke a socket, socket wrench, and cracked the head off one of the bolts trying to do them myself, but mine was a '94.

If you can't get them out, use a breaker bar or just take in into a shop and have them replace the bolts with new ones. I took my buddy's car to a couple shops to see if they would just loosen the bolts, but they refused because they didn't want to be responsible if one of the bolts fell off while we were driving home.
