The steps are similar regardless of suspension type.
First, jack the rear of the car up and place it securely on jack stands.
Place the floor jack underneath the suspension and pump it up to support the weight -- in the center of the beam, or underneath the end of the suspension arm if you have independent suspension.
Jack it just snug with the suspension, do not lift the car or it could fall off the jack stands!
With the car suspended safely, disconnect the rear shock absorbers at the bottom, then remove the bolts involved to drop the rear suspension.
Check carefully to see if you'll need to disconnect your rear brake lines to drop the suspension. If you miscalculate, you can always stop mid-drop to remove the lines.
With everything disconnected, slowly lower the jack and the suspension assembly.
