I COMPLETELY FIXED my 2015 F2Fiddy’s death wobble on Saturday…….I traded her in on a 2021 Toyota 4Runner TRD Off-road Premium w/Predator package. Now I’ve got a truck that’ll last forever and not cost $300/oil change. Loved my Duty 6.7 and miss her a little, but definitely glad I did. PS i never had death wobble. Had an 8” BDS suspension kit and 38’s and never had any issues with that thank God.
Bill, I recently added Sumo Springs Front SSF-109-40 (Blue) and Rear SSR-109-40 (Blue) on my 2005 Excursion EB 6.0 4×4 and they are great. I HIGHLY, HIGHLY recommend them. They replace the OEM bump stops and improve the ride quality.
My F350 had the death wobble from high speed left turns. Ford couldn’t fix it after numerous attempts. Local mechanic put stiffer front shocks and fixed it.
Have y’all had any complaints/solution’s to the way F450’s handle? I’ve had an issue with my 2022 F450 where it kind of wonders around and if it catches the outer edge on black top (where they re-pave the road over top of the old one) and it’s difficult to controllably bring it back onto the road. It also gets sucked into the rumble stripes they put out to let you know your on the edge of the road. This is all made worse when your hooked to gooseneck trailers as well. (Don’t know about bumper pull, I haven’t had one hooked to it yet.) Would all this have to do with caster? Or would this be a different issue I need to chase? This series has been SUPER informative and I really appreciate you putting the time and effort into getting this kind of information out there!
"Death Wobble" started in 1988 when the F-Super Duty was introduced….Drop-axle with no caster adjust built-in. There were many recalls on that issue. For anyone that has not experienced the true "death-wobble". It is not just a wobble. It is literally a steering wheel lock to lock oscillation that would break your arm if you chose to put your arm through the steering wheel spokes when it happens. It is all geometry. Even we techs of the time knew that. Ford threw many parts at that problem. Frankly, I can't believe that it is still an issue. The front suspension engineering of those trucks is BS and Ford always knew and still knows it.
12 degrees is Mercedes level. I think 4 degrees is appropriate.. 12 is way way too much for a truck. Just for fun measure the height of the truck with wheel on center and wheel at lock. It is going to be inches… No need to lift the truck that much by turning the steering wheel. 12 degrees is silly too much.
If it comes back after all this, make sure to pull the front wheels off and change the universal joints. This is a part that is missed and has been found to play a major component in depth wobble.
I replaced my rear leaf springs in my 2005 F250 with those Michigan springs, and they’re already rusting less than a year later. I live in the south and they’re rusted worse than the original ones were after 17 years.
Not too happy about that. Guess I’ll need to coat them.
Nice video as usual Bill, wondering if anyone knows who makes or where a fella can get a set of the fender protectors like are on the Excursion. I like the low profile and have been looking for some like that for a while but everything I look at sticks out too much.

Every time Bill makes a video school is in session

FIRST!
Love you guys.
Pro vw diesel guy here used y’all to learn the power strokes.
Great video!
Are you concerned 12 degrees is excessive?
So weird how my comment was deleted?
If it comes back after all this, make sure to pull the front wheels off and change the universal joints. This is a part that is missed and has been found to play a major component in depth wobble.
Really interesting seeing the troubleshooting on this one. Glad you got the chance to drive the vehicle for so long to verify the concern!
That's dudes beard is impressive

I noticed with Motorcraft alternators don't last.
