I just replaced mine. The rears are easy to do. buy shocks and buy the strut mount kits. you will need both rear shocks and (2) strut mount kits. I purchased the monroe strut which had covers on it, so I took the old assembly off, and put the new strut kit on the shock and installed it as one unit.

You should also check the rear trailing arm bushings. those get tore up pretty easily and probably need replacing as well. they suck to change in comparison, but you can buy them and have someone replace them for you.

look at rockauto for purchasing, they typically have the best prices. if you need any help PM me.
