You do NOT need an impact for the fronts. From my experience, its impossible to use the impact unless you have a special socket. The fronts are stupid easy. Just shove a screw driver in the slot and turn it with a wrench. Have a friend hold it if you want. Then remove the sway bar holding bolts and tilt it away. Remove the little brackets that hold the brake lines. there are 2 brake lines and one bracket for each line..they come off very easily with i think it was a 10 mm socket on a 1/4 ratchet with a long extension. Put a jack under the LCA and raise it just just enough to support it. Then take off the 2 strut bolts (use a breaker bar if you don't have a impact. They're not hard at all to get off unless they are rusted) lower the jack and THATS IT.
the backs are very easy. about 3-7 minutes a side. just take the covers and carpet off the trunk. Take the shock nuts off ( 1 per each side, 2 in total duh) raise the car, support the diff. with a jack just enough to support it's on weight. take the bottom bolt for the 2 struts out. The strut literally falls out. re installation is even easier than removal.. just shove the new shock back in there, put the bottom bolt on and tighten the top.
All these links show hard ways to do springs and stuff, i can do the whole suspension including springs and shocks/struts in no time. Just gotta ignore all the stupid stuff on all the popular sites.. i've seen sites that want you to take the rear sway bar off, etc. etc. just stuff that isnt neccessary at all.
