Ford Superduty Death Wobble fix

New ball joints and tie rod ends and the slack was adjusted out of the box. I asked the aligner to double check everything. The steering felt great. I went to eastern Co for the week and coming back I was changing lanes and watching the mirrors and wham, a big pothole that set off the DW. I've had a high speed wobble on a motorcycle and it was exactly the same... Slapping lock,to lock and it didn't stop,til I was nearly stopped on the shoulder. I had it up on stands today and everything is tight but I ordered a new stabilizer. BTW, Dodges are noted for this. Rough bridges and bad roads were fine til I hit the hole on one side.
