2012 250 death wobble

I've spent roughly 4 hours this evening reading forum after forum post and watching multiple youtube videos, trying to find out what could be wrong with one of my company trucks. Employee is telling me that it has graduated to being a full time uncontrollable wobble.

My mechanic has changed out a laundry list of parts, (don't have all that info infront of me right now) but it's been almost everything we could think of. About the only 2 things we HAVE NOT DONE yet is: New trac bar, and have the caster angle looked at.

Can anybody elaborate to me what caster angle is/what this does? And how I ask my tire shop to perform this and what I expect them to do? (I want to sound intelligent when I do this is why I'm asking!)

Lastly, does all of this sound correct? Have there been any new findings in the "death wobble" scenario, or has it been the same verdict for years upon years? This company I'm now managing, my boss traded a 2011 off because he couldn't get rid of the wobble after installing a lift..... just traded a damn truck with less than 20K on it because he was tired of working on it.

With my 2012 F350 I have had the death wobble when i hit a bump every once in a while. Now keep in my mind my truck is on full air ride suspension. I get the death wobble if my shocks are too soft or too stiff (Rancho 9000 adjustables).

Maybe your shocks are worn out?

My 2012 DRW developed the wobble around 40k miles. I tow heavy thru the Rockies and it scared the crap out of me when it would happen.

I took it to Ford in Tucson, Az.. the said the front end was fine that it probably was the tires. Tires still had decent tread.

I replaced all 6 and no death wobble for the last 5k miles.

I fix 90% of these by REMOVING one degree of caster with shims. They 60 $ a peice and 2.5hours to replace shims AND align. Caster will be in red on the machine but itll be good. The other 10% are usually a steering damper. Death wobble repair should begin with shims and check tire pressure
