I just change my shock today. For the front one remove the 2 screws on the lower a arm then to remove the screw on top of the frame in the engine compartment use a long ratchet extension (I use a 3ft extension) with the correct deep socket, using a back and forward movement on the bolt, it will break just under neat the bolt (don't unscrew the top bolt you will be their all day). For the back, before you remove the shocks have a floor jack hold the differential will you do the change. Unscrew and remove the bottom bolt that connect to the differential (once the bolt is remove the washer will most likely be still in place, I use a zip gun with flat blade to remove the washer) then the fun begin, I would suggest to be 2 persons for the back shock. I would suggest that one person hold the top of the bolt with ¼ ratchet (you will see a screw holding the top of the back shock to the frame, but on top of the frame there is a bolt not welded use the ¼ ratchet for that one the space is very small) will the other one use a 3/8 ratchet with a 3ft extension to unscrew the bolts. To install the new one just reverse the procedure, except screw the top of the front shock.
Once you know how to do it, to change all 4 I would estimate 1h30 to 2h to do the job, but for a first time on that car it took me around 4h (lost 2h to figure the back). Hope this help.
