You will need to start by pulling the axle housing from the car. First jack up the car, pull the tire, caliper, rotor, small retainer bolt under the rotor on the bottom of the axle housing and 2 top bolts that hold the strut to the axle housing. Drive a small wedge into the strut housing seam to open it up enough to allow the axle housing to drop once the main retainer bolt is expelled.
The following are some tips on extracting the main axle housing bolt. They can be a little tough to remove.
1) Get some PB blaster and hose all of the sections of the bolt that you have access to.
2) Make sure you have the small bolt out of the bottom, it's a 12mm on both ends.
3) Get an impact gun if you can borrow one, it will make it way easier to get the large bolt out.
4) Drive the nut off, use a breaker bar to break it loose.
5) Compress the spring. If you don't all of the pressure that is pushing down on the axle housing shaft will make it more difficult to remove.
6) If you don't have a spring compressor put a jack under the rear A-arm and lift it until the tire is coming off the ground, then get a snap strap, wrap it around the top and bottom of the spring itself and crank on the handle to get the strap as tight as possible. Then put the jack under the rear diff and lift it off the ground, that will take the weight off the lower A-arm.
7) Get a friend to help you.
8) Get a nylon hammer, and gently smack the end of the bolt WHILE spinning the bolt in reverse with the impact gun.
9) Once you get it started, take a pry bar and pry against the big washer again WHILE spinning the bolt in reverse with the impact gun.
10) Continue until it's out, keep dousing with PB as you go. When you can get any leverage anymore because the bolt is starting to work it's way out, put a 2x4 in between the pry bar and the lower caliper mounting bracket and keep going. Continue till it's out.
11) If you have to smack the bolt itself, put the nut on and drive it down to the top of the bolt. That way you won't damage the threads.
There is no majic, lots of blood, sweat and tears. I did it myself today, would have been much faster with a helper.
