ZZP has the fronts for $79.99, and the rears for $89.99. They have a great product line for most things you'll need. I had my right front done last June at a local reputable repair shop for $400, only because I was going out of town on vacation and wanted it done by the time I returned. My left front went out 2 months ago and I did it myself. It is a bit labor intensive, but if you have the desire and the aptitude you can do it. I found out about ZZP carrying them after I did mine. I spent $120 for mine at NAPA. ZZP's are listed under the " products" drop-down menu in the "brakes, suspension, handling" section.
I can give a step-by-step if you would like, but I'll have to get my manual out to make sure I don't forget something as I write it. Let me know if you need that.
