From your description John, your TJ definitely does not have Death Wobble. Shimmy and/or shake you feel thorugh your steering wheel is NEVER caused by a bad steering dampener (aka steering stabilizer), bad ball joints, or bad front-end alignment. That type of issue is invarably caused by the tires being imperfectly balanced or, perhaps, a bent wheel.
Get the tires spin balanced by a guy who knows what he is doing and advise him that you have a steering shimmy so hopefully he'll take a little extra time balancing. The bigger the tire a Jeep runs, the more important that perfect tire balance becomes to keeping shimmy and vibrations at bay.
