Yeah I haven't lifted a truck since I was in my 30's and that was 20+ years ago. Sounds like the deciding factor in this issue. My son is a diesel mechanic and I asked him about it. He had never heard of it on a stock truck, but had on a lifted truck. I have however, experienced it on a motorcycle. Not fun at all. Thanks for the replies and keeping it real.

 

My father-n-law experienced the DW on a motorcycle, too.... 35 years ago. Severed his spine and left him paralyzed from mid chest down. Got to ride in a wheelchair until we buried him this past thanksgiving. DW is a serious thing.

 

I was curious as to why you would say, try to keep the comments truthful, as if suggesting that some people are lying about the causes or if it actually exists. Strange, but now that you brought your sons feedback about it into this, it makes more sense. This is not a diesel only issue, and the deciding factor is not only having a lifted vehicle. The gentleman (Rprice32) above is an example of a stock vehicle exhibiting the problem. In his case worn parts were the contributing factor.

It might help you to understand that the term "Death Wobble" is just a nickname, Ford refers to it as sustained steering wheel oscillation, and has acknowledged that it is a real thing. They have released several TSB's on the condition to address and try to fix the issue on Super Duty trucks with non modified suspension.

Like you, I too have experienced what is called a "tank slapper" or "head shake" on a motorcycle. It is similar in a way to what is being called "death wobble" in a truck but the direct cause is different. "Speed wobble" on a skateboard is also similar with a different cause.

If you truly are interested in what causes the so called death wobble, there are many threads on the subject. What you will find are varying opinions and various causes because various things can contribute to it happening. Not because people are lying. While lifts and larger tires can exacerbate, contribute to, or in some cases cause the issue to arise, they are not the sole cause of it. And you would be very much mistaken to believe that completely stock Super Duty's with stock size tires are not capable of exhibiting the problem. Again, I would refer you to the Ford TSB's and FSA that address it on stock Super Duty trucks. Your son may be interested to read them as well.

 

Sorry to hear that. Must of been a Harley. Installed "Glide Pro" swing arm and motor mounts on my Road King, big difference.

 

I had a 1985 Honda Goldwing I bought second hand that had death wobble. I had my daughter young riding in back when it happened ...70mph on highway. Sold it the following week.

 

Bone stock 2019 F250 with 18” wheels, I got it bad. The larger tires and lifts will make it worse, but stock trucks are getting it all the time.

I will say this, I have an adjustable track bar and dual SS going on next week. Talking to steering/front end guys, the track bar will help the DW more than the SS. My front end alignment guy tried to shy me away from the Dual SS as he said it makes these trucks sticky, but based on feedback on this forum, I’m going with the Super Lift dual system with Bilsteins and a Ready Lift front track bar.

 

It was the Honda Gold Wing. He liked speed (he was a dirt track racer). Saw two friends on their bike, so the testosterone kicked in.

 

I'll use the warranty if it happens to me...... I signed a waver when I bought the truck saying that any altering of the truck will void my warranty....

 

So I have a 2020 F350, 6.7 with 7,000 miles on it. It's had bump steer on it since new. I have just dealt with it until a couple weeks ago I went and put on a single fox stabilizer. It didn't seem to help at all. It still shakes the steering wheel as often as before. Do you think it would be fixed by going to a dual stabilizer kit? Or, should I take it to the dealer? Closest dealer is over an hour away.

Thanks,
Jesse

 

I have dual BDS SS's with 37's and 4 in. lift. I've hit many expansion joints on angles and never had the death wobble. I'm far from a gearhead but the dual stablizers certainly aren't hurting.

 

I would take it to the dealer. They should provide a loaner you can take while they make the fix....

 

I also swapped the oem for the Fox 2.0. At the time I was on the stock wheels and tires and it helped for sure. Unfortunately now that I am leveled and running 37x12.50r20 the steering is very loose and I get a decent amount of vibration through the steering wheel. This single unit simple cant handle the added weight of the larger tires so Ill be going to a dual.

 

After reading this thread and my long highway drive this weekend 3 am now convinced to add this to the stock one... after they put a new one on. I was thinking that it was not properly balanced along with the bump steer till this weekend.
It handles terribly. I told them about the bump steer back in nov/Dec and said I would make an appt come Spring. He knew what needed to be done and I mentioned the wiggle and he said maybe balancing issue.
Not even 2000 mi yet

Anyone think I can put this on myself, being a strong mid aged woman ?

 

Assuming you’re talking about the dual SS. You seem to be a confident DIYer or you wouldn’t have suggested doing it yourself. I’d say, going by that, you can do it. If you’ve yanked wrenches before, then go for it. Let us know how it goes. If you run into an issue, you most likely know someone close by to give you a hand.

 

Thanks, I just watched an install and it doesn't look too hard. I have a torque wrench that I've never used, now I'm glad I kept it.
I know no one but if I can get the solid bed cover on alone I think I'll be good.
Now to pick which one.
