Use an impact wrench to loosen the top bolt. Support car on stands. [I used the front of the frame rails] place a floor jack under the lower control arm, right under the spring will do. put some pressure on the jack, this will hold the spring in, the spring can kill you if it pops out! Remove the caliper and support it, I hung it off a piece of coat hanger. Remove the rotor, and dust shield behind it. Take the two bottom strut bolts out, they will be tight. I used a 15/16" end wrench, but its really metric. I found a 5' piece of 2" pipe and used it as a breaker bar. I bent my wrench, so choke all the way up on it.
To get the top nut loose, I cut the steel band on top of the dust shield off and pull the shield down exposing the shaft. Then I clamped on it with vise grips and held it from below while I broke it loose on top. I did this all by myself, but your results may vary. I was about ready to give up and buy an impact.
