Front Suspension Bottomed Out

The front end "settles" or drops very quietly when moving the car. Set and adjust the ride height before moving and everything looks good. Put the car in gear and move forward about 10 feet at 2 mph and the front end settles as though the front tires just went flat. It just goes down smoothly and quietly. If we jack it back up, it will return to normal. We also had to drive the torsion bars out of their sockets also. Everything looks good to the untrained eye. We cannot find anything to cause this problem. It has to be something to do with the lower control arms, but WHAT? Where have all the old Mopar mechanics of the 60's and 70's gone? This doesn't make sense. I can't see the forest for the trees in the way. Or, maybe I have this problem ---:bootysha: Thanks everyone, David
