When I did mine (no motor or tranny in) I used the inner coil spring compressor to shrink the spring, set it in place and rotated the spring until in sat properly in the lower conrol arm (Kind of a ridge where the end of the coil sits against) I then used my floor jack under the lower arm, slowly brought the lower arm up making sure that I was still seated properly in the lower arm and then checked the upper arm for the same. Attached nuts on the upper and lower ball joints to hold the spindle and arms in place. When I knew I was secure I slowly released the coil spring compressor again checking that my spring was seated properly becasue if you are not you will be doing it all over again.
