There's already a number of threads on this topic so I'll just add a few more hints. Did mine today. Took about an hour once I had the tool. Bought the 8mm triple square bit in a set at PepBoys. $15 for a 6, 8, 12mm set. Plastic speaker panel slides into some clips, Needs to be slid backwards to remove. Struts come out towards the back on the inside of the hinge. It helps to have someone, my daughter in my case, push the hatch up to its fullest extension to get the struts out and in and the pins seated. To get them out, twist pin ends down and towards the inside with a pair of needle nose pliers to rotate them off the hinge. Do the reverse for installing them. Needle nose pliers are needed to get the clips off and on the pins. I used a needle nosed vice grips to get the pins in the holes. I loosened the pins by hitting the end of a long screwdriver which was resting on the pin.
Watch your chin once the new struts are in.
