Well I went to the NHTSA and filed a complaint. If the cause of this is extremely poor quality factory parts or bad design, Ford should be held accountable. Also found out there is a class action lawsuit on going for this.

 

Thanks!
If the Bozo’s here can fix it, Ford certainly can.

 

In order for Ford to actually FIX this issue, they first have to admit they have a design flaw, or poor parts source, or whatever. Now, if they admit that, they now have to actually fix every truck with the above design. And that will cost big $$$$$$$$$$

 

Not to defend Ford on this. But Its there in the other straight axle 4X4s too.
The popular consensus I think is that there is a dozen different cumulative reasons why it is possible. But no hard and fast specific component failure that can be pointed to.
The Steering Stabilizer masks the effects of whatever is actually at fault. And can do so very effectively. Bigger tires magnify it so over the years most guys who went over 35s seemed to go to dual stabilizers.
The geometry is possibly at fault. When you climb under and see angles that are not perpendicular to the ground you know there is possibility for handling issues. Every aspect of front end geometry has to interact properly with every other or you feel something.
That said. Since aftermarket stabilizers have proven to adequately mask whatever really is the cause... I see no reason Ford should not step up and just buy from the manufacturer that gives them the best deal on one that's already working...
The bump steer that I felt from mile one was the fault of the stabilizer. The shaft moved without resistance over 1/2".... That's right out of the factory. That's a defect. I doubt those stabilizers cost Ford 10 bucks a piece.
I paid $250 for my King. You could get a Rancho or Bilstien, direct replacements for much less than $100. Ford buys hundreds of thousands of these. They could likely get something comparable to Bilstein for 20 bucks a piece. Or the King unit for $100...
I was immediately disappointed with the steering feedback on my F-250 after 2 years of driving a 2017 F-450 for work. I know now that its a different front axle altogether. But I expected the 250 to feel better than the 450 due to being lower weight rated.
Now with the new stabilizer it feels comparable to the 450.
Why wouldn't you spend a few extra bucks on a 60 thousand dollar and up truck to have satisfied customers? Even charge me for it... Its not like they are shy about over charging for other crap...
As an owner... all I can say is whatever.. I love the truck... I spent my money to make it better. Shocks are next. Then tires... I didn't get the factory spray in liner because I heard they are not prepped correctly and are thinner than Linex. So Ill pay Linex to do it right. Doesn't make the truck suck or make me want a Toyota...

 

Happened to me while towing my camper on I-84 coming out of PA into NY. Hit one of those concrete pads that precede each bridge and I thought the truck and camper were going to end up in the water. Got the TSB and had it fixed yesterday. Time will tell if it's a permanent fix or not.

 

this is one of the best posts i have read on this. my 2020 has had iffy steering since day one. It was ok but not right. I tightened up the steering box and that helped but still not right. So I looked at the alignment, Humm no toe in. So I put roughly a 1/4 turn on the tierod and that is about 1/8" toe in on the ground. Truck now drives like it should. BUT while I was under it I checked everything and the steering stabilizer is wet with oil. So that will be replaced with a King unit. I truly believe the stabilizer is a bandaid for a limited design and I fixed many of these straight axle units. I will be replacing the rubber mounted track bar with a solid jointed style. Along with the shocks and I believe this will make it a solid truck from there. Should I have to do this? No but it is not worth my time for trips to the dealer. I just fix what experience has done for me in the past and I KNOW it is done right! Cj

 

Jim, the trailer could be contributing to the problem. The only time I experienced Death Wobble was while towing. I thought I had blown a tire. It was one of the first trips with my new WDH. I didn't have enough force going back to the front axle, so it may have been a little light. The front shocks (Rancho 9000XL) were also set too low, like on 3 of 9. Once I changed how I configure the WDH and set to the front shocks to 5 of 9, I've seen no recurrence of Death Wobble, even after hitting some nasty bumps.

Get this Kit!!! For stock ride hight trucks. I put this on mine, Death Wobble Gone. DW developed at 40k miles, installed this kit (with blisteens), and upgraded the steering stabilizer to Fox, after 30k more miles. No DW.

 

Anyone have the link to what King shock you can use to replace the stock stabilizer? I have a 2020 F250 7.3L Tremor Thanks!

 

I have been lucky......neither my 1998 Jeep Wrangler with 115,000 miles or my 2017 have developed the the steering wheel oscillation, better known as the death wobble.

i got my extended warranty on the TSB last week.

 

Welcome to the club. It happened to me around 29k miles 2 years ago. I took the truck to my dealer and they replaced the steering damper and adjusted the caster. After I got it back, I added a Pro Comp dual stabilizer and replaced the crappy stock tires. I've got 47k on the truck now and the death wobble hasn't returned.

 

Was looking into this kit,my truck only has 600 miles but wouldn't mind adding for peace of mind

 

I have 11,000 miles on my 2019 and have rotated the tires 3 times and also just had the tires balanced. 3 tires needed balancing. One was off 6 ounces and the others were 4+ and 3. I also replaced the steering stabilizer(Rancho) and shocks with Rancho 9000. The original stabilizer had 1” of play. Be proactive is the way I see it to keep from having the dreaded DW. My truck also felt smooth at high speed before I had the tires balanced and rotated. I never had death wobble but did feel more bumpsteer and the old one was bad.

 

Update, I brought the truck in and they were very conciliatory. Said they knew about the issue. Returned after the fix and I was told they replaced a defective steering damper. The service guy told me Ford had a bad run of dampers and assured me it was fixed. We shall see.

 

a bad run of stabilizers LOL. bob that bad run has been going for quit some time with no end in sight
