Chevy. i have done both GM and Ford 4 link rear springs. i did them on the ground. you dont need to take of any control arms, sway bars or anything else except the lower shock bolt and the quad shocks if you have them. jack the car up and let the axle sag(put the car, not the axle, on jack stands). with both quad and lower shock bolts diconnected, use a pry bar and pry the bottom of the spring out. if that doesnt work so well, jack the opposite side of the sagging axle up so it pushes the other side down. do the same for the other side. installation is easy. do the same to put them in and pry the bottom of the new spring in the seat. if you are stong enough(depends on which springs he uses for the rear) you can compress the springs a little by hand and the aid of the pry bar and they will go right in. same works on GM's(except the FBods cause of the trailing arm), but the spring pocket is on the axle(you already know this), not the lower control arm like the stangs. oh i also did them by myself.
