Step Inside: People Who FIXED Death Wobble

[JC7]

Currently have the MC 3.5 GC. Going RK on wife’s and more than likely will swap to the RK on mine too. Nothing against MC but want to evaluate both equally. Planning on offering RK for our Jeep shop.

Cool. I was going to say if you’re having issues then switch it up. I’ve gone evo and am looking forward to seeing the difference over stock.

Evo has a heck of a product out too. There’s some top tier products coming to the market

No lift on my JLUR PS - I agree it’s not the stabilizer. At this point hoping longer control arms or track bar are the fix.

Have you seen my thread “this is Death Wobble”? DW on a stock Jeep sucks and I can only imagine how frustrating that is. I have a feeling these electric power steering units might have something to contribute towards the issues.

Haven’t seen but will take a look -

Ultimately if the longer control arms and new track bar don’t work, is it then onto steering box? What’s left?

We’re replacing everything with steer smart. It’s frustrating. For you there’s even less places to look. I would recommend against anything RC though. I’ll let you know what we figure out Thursday and hopefully it’ll help others along with your journey

Dealership wanted all dough country told them stabilizer at least fox or falcon - they’re the ones paying and replacing all so can only push so much on what aftermarket parts they’re installing. Like I said, if the longer control arms and track bar don’t fix everything not sure what’s next...

DW is so frustrating because it seems like everyone that has it and has fixed it, it was something different that fixed it, but I’m sure you’ll figure it out, because it sounds like you’ve got a good dealership that’s willing to go the extra mile to get it resolved. That’s rare.

It’s only because I got FCA involved after a nightmare with first dealership - they may be going above and beyond now but welcome you to look at my previous posts. I’m still working to resolve everything and this goes back to November...

Looking forward to knowing if it gets fixed with the yetis.

Is this guy on to something? I honestly don't know but it makes some sense.

When I lifted my TJ 20 years ago teraflex gave specs for lengthening the control arms and it was spot on. What we need is a chart showing how much to add over stock for various lift sizes for each model ( sport, sport s, Sahara, Rubi, Moab).

Mine is all stock. At about 10k miles I had some steering shimmy when hitting uneven pavement. Steering shimmy will make the steering wheel shake but is not death wobble. Changing if the steering stabilizer eliminated this problem. After the repair I had some stiff steering issues in cold weather. Had the TSB performed to correct this and at 19k miles all is well.

I’m sure the stabilizer will fail again until FCA’s vendor figures out the product longevity issue. I’ll just keep having it fixed under warranty until they resolve the longevity issue.

I have a 1948 Dodge Power Wagon. Its built like a tank; 11 leafs per side, solid axle, 5.83 gears, the freaking lug nuts are inch and a half! I rebuilt the front end with all new components and it was fine for about a year, then one day I got the death wobble... I checked everything, alignment, etc, with no solution... until I checked my tire pressure. It was in the low 20s. My tires are 35 inches tall and a rim and tire weighs 140 lbs. Most of the people experiencing this also have tall tires, KO2,s and such. Tall tires are heavy, have a lot of rotating mass, and a lot of sidewall that can flex. I believe you should run more tire pressure to stiffen up the tire. So, as an experiment try running 50 psi and see if there is an improvement. It fixed my problem. If it helps you can try 45 psi, 40, etc.

I remember seeing a video a while back - anyone remember parts they used? Dealership is doing fox dampener, rough country longer control arms and track bar.

If I'm not mistaken, they tested it w/o a dampener, after replacing the other componet and no DW

Mopar just released a new JL track bar for 2018 and 2019 a few days ago. I'm not sure what the differences are or if it is just a vendor change.

On the other topic of using non-Mopar parts to fix things, my concern about aftermarket parts is that most dealers say "you altered a component in the steering system, you are on your own now on DW". Yeah, I know there is a law that says they can't do certain things, but it is open to interpretation in certain situations. Yes, there are some dealers who will even put aftermarket parts in for you, but those are VERY rare in my experience and doesn't make sense to drive 3 hours one way to find a dealer who will. Then you have to go back to that same dealer for all future steering related problems since the local dealers won't touch it now.

Also, I found the product description bulleted items in this Synergy MFG drag link VERY interesting. I'm tempted to try this as it seems all drag links "flop" when you pull up on it. That can't be good and most JL owners are saying they all do it, but no one knows if that is a good or bad design. But still, this is interesting:

https://www.synergymfg.com/synergy-jeep-jl-heavy-duty-drag-link-kit.html

• Increased tubing wall thickness improves drag link strength and steering feel. Offers a more direct connection to the road/trail compared to stock.
• Bar is fully welded, unlike the crimped OEM design.
• Pitman arm side tie rod end is a single plane design to eliminate unwanted drag link flop. Drastically simplifies installation and only allows necessary degree of movement.
• No factory drag link components need to be reused.
• Includes Synergy HD Metal on Metal Tie Rod Ends with a Single Plane version at the pitman arm side to completely eliminate Drag Link Flop.
• Drag Link is CNC formed from 1.5 inch x .250 wall DOM tubing
• Both ends of the bar use pinch bolts instead of jam nuts to simplify installation and adjustment.
