WOW Some GREAT looking trucks and pretty dang awesome info here!!!

OK so far there is a TSB that addresses this; thanks AquaMancw waiting for an update on that and the idea the 6.7 is a heavier engine so more weight on the front axle of the Diesel equipped trucks.

Of those who have experienced the dreaded (announcer voice) Death Wobble.... How many of you are running the 6.7 vs 6.2?

Sounds like shocks and stabilizers are the go to fix...

 

My businesses have had many F150, F250, and F350 trucks, many years and models, driven by dozens and dozens of people, with everything from no load to overloaded, and when I ask them not one has ever had the experience of a death wobble.

 

Got my truck back, took it for a spin on the highway did not get any wobble, yet.

Looks like shocks, steering damper and camber or all the noted repairs that have "fixed" this issue. Hope you never get DW again!!!

Can you post the alignment spec sheet? Curious what they dial in caster, camber and toe to.

 

there you have it folks. ford is admitting theyre fully aware the '17-'19 trucks have death wobble. cut and dry in black and white

 

Yep, it can happen, just like it can happen to every other straight axle front end vehicle out there.

I've had the trucks listed in my sig below - The '12 F350 (stock suspension) was the only one that had issues with death wobble, twice in 60K miles, both times cured under warranty with multiple new front end suspension parts each time. BTW, if you ever have experienced DW, you will never say something like "I think my truck has DW" - It is such an extremely violent event that you will have no doubt what it was after it happens.

 

No Death Wobble for my 2017 F-250 XLT with 8800 miles. The suspension is completely stock, and no wheel/tire upgrades.

Just creaks in the doors when I lean my leg against it while driving.

 

2000 F 350 and 2017 F 350. No suspension mods and no wobble.

 

2017 F250 4x4 FX4, Camper pkg. never experienced death wobble, bump steer yes

 

2006 F250 XLT 4x4 SRW Short Bed Ext Cab Gas Stock Suspension: No DW
2006 F350 XL 4x4 SRW Long Bed Reg Cab Gas Stock Suspension: No DW
2006 F250 XLT 4x4 SRW Short Bed Ext Cab Diesel Front Level: No DW
2009 F250 Lariat 4x4 SRW Short Bed Crew Cab Diesel Stock Suspension: Yes DW
This truck like the others, was used for plowing. I think excessive front end wear was the cause, and there was no great solution. I replaced front end bushings and finally replaced the trac bar and that helped a lot. Steering stablizers also quieted things down. There was no way to fix the issue.

2013 F250 Platinum 4X4 SRW Short Bed Crew Cab Diesel Stock Suspension: No DW
2017 F350 Platinum 4X4 SRW Short Bed Crew Cab Diesel Stock Suspension: No DW

 

well like other people have said, somebody can get in a crash if they dont get it sorted out.

 

 

That is ABSOLUTELY the case.


Short version: My 2015 was flawless until 83k miles when it happened. Ironically, I was within a couple of weeks of trading it. My local dealer said nothing was wrong, so I replaced shocks and steering stabilizer with Rancho 9000s. It did it again on the way to trade it in. The trading dealer determined it was a worn steering stabilizer (though the new one was only 500 miles old.) Whatever....I just decided it as their problem and chose not to argue but knew they were wrong.

The reason I am so interested is because I can feel the same thing hiding inside this new truck. My 2015 KR had the towing package had race car-like steering and handling, no body roll, no bump-steer, no issue at all. This new truck has lighter front springs and exhibits front corner body lean/roll around the same corners I drove with the '15. I feel a lot of inputs into the steering wheel and on rough overpass transitions on the highway I can feel it wanting to wobble, though it hasn't yet. I have a lot of race car suspension experience, and have owned a numerous SFA vehicles. Obviously this is a design flaw, but truly curing it still seems to be elusive. My '18 has 5200 front coils whereas my new '18 has 5200. The shocks on the new truck seem much softer as well. So my plan is to upgrade coils to the same 5600 lbs that was on my '15 just to be able to compare, and then start looking into some caster correction, and lastly installing firmer Fox shocks and stabilizer. While I think installing shocks and a stabilizer is just masking the problem, I at least want cure the nose roll and evaluate the caster changes. I may even wind up at 6k front coils where you are. I think its a design flaw that cannot be corrected, but possibly isolated and contained.
