A CHASSIS ENGINEER Solved My F-250 DEATH WOBBLE So CarMax Wouldn't Have To

3 жыл бұрын

An engineer reached out to me after I made the last video about my F-250 and said he could solve the dreaded excessive wheel oscillation. Roy knows this issue inside and out and had a few simple tests we could run on the truck to quickly pin point the cause of the death wobble. Within minutes we found the problem and spent the rest of our time trying to reproduce it, which happens to be one of the hardest problems techs face. If you can't properly diagnose it the truck gets a steering stabilizer and kicked back down the road to fail again in a few thousand miles as the stabilizer wears out. I also have it on pretty good authority that CarMax doesn't work on heavy duty trucks at all so all of this is actually being done at a Ford dealer down the road. Can't really blame the greatest car dealership ever, they're just writing a check.

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.

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!

Adaptive Steering or whatever my educated guess, especially if the issue is intermittent.

We can't fail a vehicle for loose ball joints in NY simply because some vehicles had them with slight up down movement by design and the state had to remove the rule because brand new cars were failing. As for the boots, failing for that is laughable. It's worth warning the customer so they can anticipated the cost or replacement within the year but not failure. You can also get grease showing like that on a joint that was simply overgreased, not torn.

Death wobbles can be the result of different parts going out. No two are the same. Replace the whole front end, and it might still wobble.

@@danieljones317 I own a Patrol, so am well experienced in death wobbles. Tyres are a major culprit, along with panhard bushes, bearings, rod ends. And yes, you can fix everything (seemingly) and they will still wobble, but it means you misses something like maybe castor correction.

@danieljones317 3 жыл бұрын

@@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.

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 Жыл бұрын

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 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.

I have a 2017 F-250 that had the death wobble at 29k miles. I replaced the crappy Continental tires (very worn), installed a dual steering stab and the dealer replaced the factory steering damper and adjusted the camber. So far, 20k miles later, zero issue with the wobble. I have the same play/knocking with the center link but on the steering box side and haven't developed the death wobble again. The center link seems to be a common failure and many places can't keep it in stock.

Another check to do is to see if the axle pinion flange is pararrel with the transfer case flange, otherwise, unless CV joints are used, the UJ joints can initiate the wobble.
