Incredible value when you can do the work yourself. This job costs at least $150 to work. The back is easier to replace than the front. They are smaller and lighter. Remember to order replacement set screws and be prepared to drill and remove. The only people who can successfully remove them with an impact wrench probably live in dry climates like SoCal or AZ. I have included before and after photos as well as the results of removing a stuck set screw.
