A couple things from experience working on front ends. I first encountered "death wobble" back in the 80's on 70's Chevy 4x4's. They used a solid axle and Ford didn't. Fixes were 2 fold. Caster setting of (min) 3 degs+ , 4 deg + is better, and a steering damper on the center link between the wheels. Camber and toe set to factory specs. On some trucks we have made custom bushings or shims to get the desired results. This has resulted in 0 comebacks and very happy customers. Take what im saying for the price you paid for it, but if you disagree ask any custom motorcycle builder about front end geometry.

[@brentbosworth8845]

YES, This guy know what he is talking about! Caster angle HAS to be at least 3 degrees positive and ALL your wobbles will stop. You will need new bushings on the top of the axil for this. Good mechanics will also tell you they will need to replace those bushings with aftermarket ones. Don't just ask for them, let them say it and you will know you have a good garage. GL !

Claiming this has been solved without showing actual proof is not an accurate description at all.

As a licensed technician with most of my career spent working on Super Duties for a living, I appreciated this video. It was the most accurate, and non-bullshit video I've seen in a while. And thank you for addressing the fact that dampers are just a bandaid. Also, fwiw, that RH lower TRE is always sloppy a brand new one will have a bit of play. That drag link end was whooped though, and almost guaranteed the issue. Shocks, jounce the front end with 2 or 3 big bounces, and watch the vehicle. It should settle after 1-1.5 oscillations. A roadforce is mostly just to chase hard to catch issues, or imbalances. Cross rotating your tires will help isolate it too.

Finally, someone who knows his shit. 99% of all Death Wobble cases can be traced to either a worn part, or bad alignment, Most likely both. Usually adjusting the Caster to 4* or more cures it once and for all, but you need the proper shims. Factory max is 3.4* Struck a bullseye on the trailer issue too, corrosion or loose pin in the harness somewhere. To best envision Death wobble, find a shopping cart with one of those wonky wheels. Thats exactly what the truck is doing. Changing the angle the wheel pivots at on the vertical to have the top lean back a bit more corrects it. Downside is the steering is stiffer and returns to center much faster, which is what you want! If you have this, forget the dealer, forget Carmax, find a GOOD alignment shop that deals with trucks and have them replace the spindle cams for more caster adjustment and lean that baby back. You wont need no stinking steering damper!

As a Chassis Fab specialist and someone who has fixed this issue on a number of SD, it is in fact the panhard ball joint and bushing 99% of the time. If you can rotate the panhard bar by hand even just a little it's time to replace both ends. I your case I would upgrade to the Heim Joint setups out there since you pull with it 50% of the time, little $$$ but worth so you're not having to replace the ball joint every 30-40k.

[@danieljones317]

@@einfelder8262 personally, I think it's bad design. The setup has way too much inherent flexibility, for one thing. The axle is heavy enough to override any correction that the bushings can give. That being said, there is one sure fix for it. First, do away with the rubber, across the board. For the parts that have to deal with direct shock, go to a polyurethane bush that is double the durometer of the original rubber bush. Leaf spring eyes, especially. The panhandle bar bushes should be replaced with something even less forgiving, such as delrin or nylon, and the should have a way to lubricate and seal the unit. Delrin for the axle mounts of the stabilizer bar, and polyurethane for the end mounts, if not doing away with them and using ball joints. The upper and lower ball joints replaced as a matter of course. Tie rod ends inspected, and possibly replaced. Wheel bearings replaced as a matter of course. If there is a steering damper, it should be replaced with one that has more damping effect. Rebalance the front wheels, and if the tires show any uneven wear, even if they are not out of balance, they should be rotated out, or replaced. I, personally, would also be inspecting the frame for cracks, especially around the welds. A frame that is rusted thin will have more flexibility, and can help to exacerbate the oscillation due to lack of resistance to flexibility. Even body bushings and mounts should be inspected, as that can set up harmonics.

[@BreakerBreaker1320]

My 2016 had it. I added a front receiver hitch and stiffened up the frame and it is gone. Nothing else was worn enough to replace. It doesn’t matter what anyone thinks, these frames on the front end are not stiff enough and the excessive movement prematurely wears out the steering assembly because its not heavy enough. Once I connected the front frame rails with a 2” receiver hitch, the death wobble has been gone since. I also lowered air pressure to 55 psi because these trucks require E-rated tires with an incredibly stiff sidewall. Once you put the weight of your vehicle on the front end, you can see the issues but in the air on a lift, you are not 100% going to be able to diagnose worn links in the steering assembly unless it is terribly bad. Replace the drag link on that truck with a heavier aftermarket unit and get rid of that split collar oem unit.

[@Cookie-Dough-Dynamo]

Any old timers here? My dad's old dodge, the one with the steering BOX, had a worn box with tons of slop. No death wobble. It just drifted left to right constantly. My old ranger, two blown ball joints in the control arms and worn out steering rack and your rod ends. 360,000 miles. No death wobble. This is a design issue. I would bet the geometry was set in such a way that the toe and castor are too neutral. The components don't load up to a safe position while driving. Instead, because of the light/neutral geometry, the slop in the components load and unload causing the death wobble.

[@robert5]

You are right, too little caster in these trucks so when the steering parts start to get loose there is not enough caster to stabilize the front end. Less or neutral caster is the cause along with the other worn loose parts.

My ‘08 Jeep Liberty had a “death wobble” when I bought it used a few years ago. I got it pretty cheap because of the wobble. The problem turned out to be the front left brake caliper sticking and grabbing when it warmed up. Replacing both front brake calipers fixed the problem. Nobody ever talks about how the brakes can cause this problem. An easy to get out of your vehicle and check the temperature of your wheels after the wobble appears to see if there’s a possibility of a sticking caliper.

On my 2015 F250, the trailer connected and disconnected issue is the (I think 32-pin) connector for the canbus system that is attached to the parking brake frame via a christmas tree fastener. The TSB was to move the connector to the dash frame with a ziptie after inspecting the pins on both sides of the connector for damage. IT was common enough a problem new that the there was an alert as early as 2014 before they even did the TSB.

[@mcgizzle7835]

Hey JR I had a similar issue with the trailer disconnected. It wound up being the trailer itself. It was a bad electrical connection point on the electric trailer breaks.

ive done 4wd conversions using that dana 60. when we rebuild them we use an aftermarket kingpin insert to add about 4 more degrees of castor from factory. castor is super important, most manufacturers dont put enough in.

[@BroncoDriver77]

Had an issue with the trailer connected/disconnected on my 2012 F-250. Replaced the trailer lights/brake receptacle on the truck and still had an issue. I switched trailers and the issue stopped (2020 trailer had issue, 2008 trailer did not have an issue). The way the system works is the truck sends a signal through the trailer brakes and back to the electric brake controller to indicate a trailer connected. The resistance was in the trailer. Replaced the factory crimp/splice connectors on the trailer electric brakes with solder connections and heat shrink. Towed that trailer from Maryland to Indiana to Texas with no issues.

I bought a new 2004 F-150 in '04 that developed a death wobble during the first year of ownership, so bad it was difficult to steer on the highway. The whole truck shook and wobbled. After taking it to the dealer a number of times, and much research, without success, I started taking wheels off one at a time, checking for problems. Finally, while looking t the rear brakes, I noted signs of heating on the emergency brake drums, inside the rear disc brakes. The cam that turns to apply the emergency brake was rusted in place, and would not release. As I drove, the pads heated and expanded to bind in the drums. They would heat, bind, stop, cool, loosen, then repeat... All I did to fix my problem was to remove the shoes, break the rust on the cams, then loosen, and lubricate them with disc brake pin lube. I still own my truck, now in 2021, and have not had any problems with the death wobble since. My theory is that while launching a sailboat, and backing the trailer in much further than with a power boat to get the depth needed for the 4' keel to clear the trailer, and hull to float, I had put th rear end of my truck into the water beyond the height of the rear wheel hubs, then come home and parked my truck in my steep driveway with the emergency brake on for a few days, as it was not my primary driving vehicle. Now, whenever I have a rear wheel off, I check the cam to see that it is still moving freely. Try the SIMPLE THING FIRST!! The problem is just finding it.

[@kevinhitchcock7062]

My 07 F250 4x4 did at about 50 miles on it. It was brand new. Ford said it was because I put Nitto Terra Grapplers that were a little bit bigger. I put a stabilizer on it and it helped a little. Truck didn’t come with the stabilizer shock.

Check out the front axle u joints, mine were seized and you couldn’t hardly drive it. Everyone said bad front end components, I put into 4x4 and drove in circles in my gravel parking lot , which forced the u joints to flex and break loose and the problems went away. Take it for what it’s worth, it worked for me.

[@markperalta2995]

The panhard rod ball joint has excess play. At 7:00 of the video, you can see the panhard rod at the level of the white paper sticker where it intersects with the upper differential cover bolt. You will notice the sticker having significant movement in relation to the bolt. You should see no movement by just looking at it with your bare eyes. That ball joint looks inadequate to solely handle the lateral forces of that big rig. Or maybe it just ran out of grease inside, causing the premature wear and excess play. Also check the upper mounting bracket of the panhard rod for unnecessary play. Also, that steering damper is not at optimal placement (drag link-to-frame setup). The steering damper is most optimal when mounted in a tie rod-to-axle setup. Hope that helps.

JR, check out increasing your caster shim. Any auto parts store has them, Ford doesn’t have enough caster in the super duties. I have a 19 250 Platinum. Look at Carli caster shims for the degrees, then go to Napa or where ever. This alone solved my death wobble with only 700 miles on it.

I’m a Ford technician and the steering dampener is definitely a band aid but its one that Ford issued a recall on. That is typically why it gets replaced all the time. I do quite a bit of front end work on Super Duty trucks. Track bars and drag links are pretty common on heavily used trucks.

[@johnpeters9793]

Small correction.....Ford actually calls it an extended warranty on the damper. Not sure why, but I got the letter. Anyway, my 7500 mile F-350 did it a couple times a 1/3 of the way into a 2500 mile trip. Never did it again. I'd imagine there can't possibly be anything worn out. Made it home and the dealer did the damper. Haven't driven it any substantial miles since. This is my 3rd 4WD Super Duty.....1st one that's ever done it.

Amazing how many death wobble videos are on YT and all of them can be fixed by smart repair and standard maintenance... So glad you addressed something that seems to have gone to the Wayside, and that is the knowledge that customized vehicles require customized attention. When did we become such a group of bolt-on Warriors that cry whenever the vehicle doesn't perform it's basic stock functions because of modifications that should have probably not been made in the first place. Thank God I grew up working on old school cars having to fabricate parts and understand how to make them work instead of buying them off the shelf and bolting them on. There's nothing wrong with bolt ons, just have to realize what the modification is doing to the vehicle and how it may affect everything else. Honestly, do you think the Six Million Dollar Man could have really had bionic legs and a bionic arm yet his back and spine was all human.? LOL
