Death Wobble solution?
Looking to get a 2015 or newer F350 to replace my 99 F350. My 99 F350 has leaf springs on the front end so I've never experienced the "death wobble". It's making me a bit hesitant.
Does anyone know of a solution for this condition?
Has anyone experienced death wobble with airbags in the front coils? I've seen replacing the track bar with one without the rubber bushings. And also seen a kit that provides caster adjustments.
Any info and experiences would be awesome and I apologize if this has already been covered in another forum.

Regular inspections and maintenance. Death wobble is caused mostly by loose or worn parts, poor alignment and oversize tires exaggerate the problem, even leaf spring trucks can get it. If you get it on close to stock size tires, there's most likely worn parts such as ball joints, tie rod, wheel bearings, steering box, bushings, etc, etc, could be anything, or a combination of things, in the front end. With oversized tires, it could just be the steering /suspension isn't strong enough to control the wheel, in which case it's time to upgrade to HD components. Bigger tie rods, bigger drag link, HD ball joints, steering stabilizer or even hydro assist.

I'm not sure that the newer coil spring straight axle suspensions are any more prone to death wobble than the older leaf spring suspensions, If you look on line their a plenty of death wobble complaints with leaf spring suspensions. I'm not sure whern or why this started, I know ford has been using coil sprung, radius arm with track bar suspension on their half tons since the early 70s. I don't remember death wobble being a problem back then.
Another words I would not let death wobble stop me from buying a newer truck. Its a small number that have this issue.

I'm guessing it's a matter of all the suspension bushings and steering components hitting a point where there still individually in spec, but stacked up there's just enough slop to cause issues once you hit the right oscillation frequency. I've wondered if adding more negative caster to make the steering less twitchy might help.
