Owen,
Poor choice of words on my part, yes the torsion bars are still loaded. I was looking at the suspension and steering section of the service manual (found on this site), under compensator removal on page 15......"it will be necessary to take the load of the body and frame off the compensator bars and links". So I said at rest, my bad, as the kids say now days!
You kind of made my point that it should rock back and forth. Happy said it will not come down in back. So it sounded like something is keeping the back end up.
The SAE paper is on this site. I will attempt to read, but I am not an engineer, nor do I play one on TV. I am just a shady tree guy. It will probably be over my head. The movie "The Safe Road Ahead" kind of discussed the torsion level suspension, so that is also where my question comes from.
