I think I have the Death Wobble, however it has only occured intermittently while braking above 40mph. The tires oscillate violently from side to side shaking the h*ll out of the truck, the harder I brake the worse the oscillation and stops when I release the brakes. During my last trip it was so bad I had to use the trailer brakes to slow the truck. I replaced the track bar with the moog part and put on a Rancho SS. These items had no effect on the wobble. Reading through some of the other recent posts it appears that most people get the wobble as a result of hitting a bump in the road. It seems that my brakes are the cause of the wobble but otherwise I have smooth braking without pull. My truck has 23K miles, 75% solo, 25% towing. 
Any suggestions appreciated
Thanks
