To remove the rear shocks the bottom is obvious, the top requires removing the rear seat back.

To remove the rear seat back, push the red buttons on the rear seat bottom, lift up the front and move it forward. Then you can reach some small (I believe 8MM) screws on either side at the bottom of the seat back. As I recall, there is also one below the armrest in the center. Once all the screws are loose where the bottom moves forward a few inches, then pull the seat up to loosen some tabs that hold the seat back at the top.

Lean the seat back forward and you will see the shock tops.

Good luck,
