You catch a case? Think the consensus was there are several factors that play in to it. Any worn steering component part may cause it, worn ball joints, track bar bushings, sway bar bushings, bad shocks....sorted any of that stuff out yet?

I've not had the death wobble, but I will say getting new bushings and balls joints helped tightened things up quite a bit. I was amazed at how much it had changed over the last several years do to wear. I would also check with Quigley and get the proper alignment specs. Turns out the place I was having my alignment done said the Quigley spec was slightly different than what he showed for an F350 of similar vintage and once he aligned it to the Quigley spec it was much less twitchy it freeway speed.

Thanks Good advise.
My 4x4 was done buy a fab shop called CBI in Idaho Falls only 2 years ago before I bought it.
it seem to only happen under 50mph. But it always feels like it's on the edge of happening, makes for a tiring day

Search this site for DW posts. Lots to read. Best advice is to avoid throwing a steering damper on it except as a very last step after everything is back to factory specs and aligned.

Well they aren't working for you. You may find that reading all the DW posts here will help as well as an alignment shop that truly understands the science of a vehicle moving down the road. As I said earlier restore the worn parts to a solid baseline, research the data here, and make one change at a time. Also find out whose system was installed in your truck.

A good way to check for worn components is to pull the front tires into a parking curb and have someone inside move the steering wheel right and left as you look at all the components. This will show worn track bar bushings, tie rods, etc. Be sure to have it in park and the emergency brake on. Good luck! Caster angle is also a culprit in Death Wobble many times.
