The procedure I listed is a potpourri of several put together on this forum. One thing I forgot to list is the removal of the swaybar before dropping the frame, done at the same type as unbolting the shocks.

So the detailed revision goes:
Lift rear with floor jack from the subframe.
Support with stands at chassis, not subframe, do not remove floor jack from it's position.
Unbolt bottom bolts hydro shocks. Or top? But not complelely unless being replaced
Remove swaybar mounts at control arm only
With floor jack slowly drop subframe until springs 100% unloaded.
Replace springs.
Raise subframe with jack.
tighten lower hydro shock bolts and swaybar.

From the looks of it last night, this seems correct. Will know in a few days for sure and will revise as needed.
