Even a very novice mechanic can do this in just a few hours at most, and that is going really slow and methodical. A minimum amount of tools are all that is needed to get this done and you will be proud of your achievement when the job is completed.
Materials Needed
Hydraulic floor jack
Jack stands
Ratchet and socket set (17 mm deep well, 10 mm, 5/8" socket), extensions.
Flat head screw driver
Step 1 – Open the trunk and remove liner
Pop open the trunk and remove the trunk liner. Use a flat head screwdriver to pop the center inserts of the plastic tabs that hold the trunk liner in place. The rest of the tabs will pop right out after the center plug is removed. Be careful when popping these plugs as they can easily break.

Never work on your car without using jack stands on level ground. Chock the wheels for additional safety.
Use a 10 mm socket to remove the two bolts from the plastic cover beneath the rear axle. Pull the plastic cover and set it to the side. Remove the 5/8 inch bolt and nut combination from the lower shock to dismount it. Lift out the shock, it will likely need some contortion to remove it out of the wheel well.

Pro Tip
Be sure not to damage the plastic dust cover over the rotors when removing the heavy strut assembly from the wheel well.
Step 5 – Install rear shock absorber
Before you can install the new shocks, you will need to compress the replacements to the size of the OEM shocks. Use twine or very long zip ties to secure the compressed length. Install the shocks at the lower end first. Put it in place at the bottom, line it up correctly at the top and snip the twine or zip ties allowing it to uncompress into position. Secure the lower end with the bolt and the 5/8 inch nut. Replace the plastic cover and replace the 10 mm bolts under the rear axle. Replace the rubber biscuit, washer and the two nuts at the tower assembly inside the trunk. Then replace the trunk rear wall liner.
