the front mounts hold the bearing, and more than likely will come apart during replacement, so plan on replacements. The rears should be done, especially if the car is making that strange knocking sound on bumps, plan on replacements.
The fronts can actually be done with the strut assembly in the car, it comes right out the top. The rears dont have springs on them, because of the leaf spring.
You will need to rent the autozone tool to get the fronts out.
