I know this has been discussed before. But I am seeing increasing signs of the DW in our 2012 F350 6.7L 4WD. I see that dual steering dampers is being put forward as a cure. I have a Bilstein single damper but it is over 5 years old.
So has anyone out there tried the dual dampers, did it work and which system did you use? Thanks.
Lastly do my 5+ year old Bilstein front shocks need replacement too?

Don't forget the upper and lower ball joints, they were the culprits in my 3/4 RAM. Death wobble scared the heck out of me at 60 mph. Took truck to the dealer, they said the ball joints were within spec, went to a Napa garage and the guy wouldn't let me drive home, the left upper almost fell apart it was so worn out.

Death wobble is a result of worn out/broken parts.

Steering dampers only hide the problem.

Check:
Ball joints
Wheel bears
The ENTIRE steering set up/system.
Tire balance
Lug nuts
The ENTIRE suspension set up.


Death wobble can be any combo of the above, so you must check them all.

I'm a big fan of Bilsteins.

Bilsteins are good for at least 100,000 miles.

I have a good mechanic finally I'm going to take it in and let them to give the suspension a careful check at the beginning of June.

My 2017 had the DW issue. I took it in at about 45000 miles and Ford replaced the steering dampener under some kind of extended warranty. It would get shaking quite severely. I tried speeding up ..... letting go of the steering wheel or jabbing the brakes ..... seemed like the only way to get it to quit was to come to just about a complete stop. Anyway after the dampener was changed it handled nice.

"Death wobble is a result of worn out/broken parts." Not true! Everything in my front end is new and I just had it aligned and tires balanced. 200 miles later, I got my first DW Friday when I hit a pothole. Craig

Some points:

1) What is YOUR definition of death wobble, then?

2) You say, "Not true!"
Please back up that claim so we all can learn.
Your point tells us nothing that re-enforces your claim.
I smell a huge assumption on your part.

3) Is literally EVERYTHING that affects your front suspension and steering system new?
IS THE RIG NEW???

My 2012 Super Duty has 213,000 miles on it and it still has all original suspension parts except for shocks. My truck experienced the DW scenario twice in close proximity around the ~80k mile mark when I was running BF Goodrich AT tires when they were about at the end of life. Once I changed out those tires to a different brand it hasn't happened since.
