Dodge Repair: 2006 dodge ram 3/4 ton, death wobble, bar bushings

Question
Hello,
     I have a 2006 Dodge ram 3/4 ton long bed with a cummins engine.  I have been having the "death wobble" issue.  On the freeway above 65mph if I hit a bump just right the whole front end starts to shake very bad.  I have replaced my track bar bushings and no change.  I have tried to look up some facts on the internet and it seems everyone has a different reason.  I have checked the tie rods, replaced the tires, everything underneath seems to be ok.  Any ideas on this issue?

Thanks, Mike

Answer
Track bar bushings are not replaceable. Did you mean to say you replaced the track bar? One other question, have you replaced the steering stabilizer? That is the common failure for 4X4 trucks, which I'm assuming you have. As a note, there is a Safety Recall for this year truck that may apply. Stop into your local dealer to have them check on it.
