Axle U-joints, worn ball joints, worn tie rod ends, bad steering damper.......death wobble ONLY occurs when something is REAL loose.....Bar none...
Live spring and the steering linkage set up has been used for years.....I've had MANY old trucks with the set up and I've NEVER had death wobble. Probably because I've kept everything up to snuff. Those who complain about it don't have a very good serviceing criteria. 
Badly Warped Rotors will also cause this as stated above....been there done that and didn't believe it until it was proven to me on my own truck...

If the truck goes into "death wobble" just by hitting the brakes with out of round rotors, then there's something else VERY loose....Track bar ???
Then why did replacing the rotors on mine cure the problem...???? Also happened on my Jeep Wrangler....No Loose Front End Parts
I have experienced wobble due to other reasons...bad stabilizer shock and other worn-out parts on other vehicles as well....but don't count out the brakes.
I spent a bunch of money replacing front end parts only to find out in the end it was the brakes.....you can choose to believe or not

Worn suspension parts. On the 94+ Dodge trucks, start with the track bar then move to the ball joints, then the tie rod ends. If those parts don't cover it, we will give you the next list. Gene

Just as Poorboy says....And.....I wasn't saying out of round rotors wouldn't start something happening....What I'm saying is that if just out of spec rotors send the front end into the death wobble, then there is definitely something else that is NOT right. I worked on these trucks for 40 years....those rotors would have had to be out a mile!!!
Also....there is a discernable difference between the "Death Wobble" and just rotor induced shaking. The death wobble is basically non-controllable when it happens unless you get the vehicle slowed down. Believe me...you'll KNOW when it goes into the wobble...

It's not just 4X4s.... My '98 SST did for years if I hit the smallest of highway road cracks. I tried hd shocks and thought it did the trick until about a year later when it's worse "death wobble" occurred.. totally terrifying 
I swapped out the shocks to Monroe Sensa-Trac's and it's never happened again.
It's been maybe 7 years now

Not always true....if you noticed in my application all front end components were replaced first as I thought the same thing you are stating.....although after a complete rebuild it still wobbled until I replaced the rotors and that cured my problem.
Knowing this when my 2001 Jeep wrangler experienced the same problem I had the rotors ck'd....they were found to be warped and it cured that one as well.
Not saying it couldn't happen from worn out front end parts as I had one the I cured by replacing the Stabilizer Shock on a 4x4.....

The wobble I described being cured with new rotors was the same.....you had to basically come to a complete stop or slow down significantly for it to stop.....

at work we have a 99 4WD 1500 when you hit the brakes it goes nuts feels like tires are falling off . I havent checked it out yet looking for tips. truck has 237,000 Miles on it
My later model trucks have done this. I has a 2006 4x4 that started doing it at 18,000 miles! I had the rotors resurfaced and it was perfectly fine....until 30,000 miles.
My 2007 2wd started it at 175,000 miles. Again, new or resurfaced rotors were the fix. I refer to the problem as "Brake-Shake." I'm closing in on 200,000 and I'm feeling the shake again. To be clear though, I do drive aggressively. I've driven on curvy roads above the speed limit and need to slow quickly for the tighter curves. Brake pad life is still great though as long as I use OEM Mopar pads.

I've seen guys come into the shop with double stabilizers.....still have death wobble. Usually a combination of trac bar,axle joints, ball joints or tie rod ends being worn. Old 60's , 70's and 80's trucks that had no stabilizers. they still got the wobble. On the 60's and early 70's trucks with the closed knuckles, you would sometimes find that the brass cones on the top of the knuckles were absolutely shot. A couple of new cones and some shimming and it was fixed. My'69 was bad for this especially with the big 35's and 12" rims....it would wear out those cones every 5K or so.  If parts are worn, out-to-lunch rotors are certainly going to start things goin' !! Death wobble at 60 MPH is NOT a pleasant experience.......

Brake pulsation is not death wobble....its just brake pulsation,regardless of severity.on a solid axle jeep or dodge,death wobble is most obvious when changing road surface,and is almost , if not always the steer stabilizer shock.a track bar will make it wander,but not contribute to death wobble.
you are wrong.. DEATH WOBBLE is definitely caused by a bad track bar.. I have had it happen to me twice, both times in a 94 ram 2500 4X4.. First time I was about an hour from home , steared to avoid some debris in the road when all the sudden the truck began jerking back and forth very violently.. I thought something broke in the front end stopped and looked for something broke didnt find anything so I drove on home way under the speed limit just in case and had it happen again on a curve about 6 miles out.. Was talking to a guy that I work with that had almost exactly the same truck and he told me to check the track bar, I did and found that the ball joint end was so wore out the ball came out when it was turned to the right position.. bought a new track bar from Autozone and installed it, did good for about a year.. then coming home one afternoon I was coming around a curve in the road when it went into its death wobble.. the Autozone track bar had snapped in two in the middle of the U bend.. went and bought a new Dodge track bar and put it in and never had any more trouble..
