To get the front shocks off we pulled the wheels off and used a vice grips to hold the shock from spinning. You might be able to do that without taking the wheel off but removing the wheels gives you more room to work with. On the rear you just need some pb blaster and a wrench. Note that the nut is welded to the mounting bracket and won't spin off no matter how much you try, you just need to focus your efforts on removing the bolt itself. Good luck!
