2018 2 door JL
Now the dealer has replaced the SS again, citing they cannot find anything wrong...I also have video documenting the wobble. The third SS has resolved the wobble for now, but my confidence is not high that it will not return.
I had considered spending the money and throwing beefier aftermarket parts at the problem, but I plan on standing my ground and making them fix the issue. It's not like I saved money and purchased a used Jeep with worn parts...this is a new vehicle and FCA should make it function like one.
I guess the question is what have they checked? Alignment, wheel balance, all front end bolt torque? all need to be correct or problems occur. If you have slop in steering you may also have a steering box needing replacement like so many others have had to do.

I guess my rule of thumb is if I lifted it, I gotta correct geometry, if I did not dealer needs to fix it.

My 19' Rubicon will be delivered in a couple weeks. I daily drove a lifted TJ with up the upgraded heavy duty steering linkage. I never experienced DW.. Im planning to add a lift to my new rig at some point, along with steering upgrades. Can the steer smart linkage be added to the stock height rig or is it only after installing a lift? I like being proactive on items likes these. Ive seen someone post something a out a add-on support bracket for the drag link? Is that worth checking into?

2018 JLU
Also, my '18 JLU hard top sport has a standard transmission, was built I believe in April 2018 and purchased late October. It is completely stock. The Bridgestone all-seasons car tires it came in with are run at 36PSI per the Jeep's monitoring system. The spec sheet from the Bridgestone page says these tires weigh 34lbs. I bough a used set of JL OEM rims to mount my former 2012 JK BF Goodrich k2's 33" (285's) tires. I think they weigh about 48lbs. I have not install the larger BFG set on the vehicle yet to see what happens once the new aftermarket SS is installed with everything else original.
On 2/27/19 I had the SS replaced at the dealer with the Rough Country made unit the dealer ordered from the aftermarket vendor. No change. The wobble is minimal, but not gone. As I said on my other posts, the biggest impact made to improve the wobble was when the dealer replaced the track bar. A new OEM SS (three of them) would take care of the minor wobble for about 100 miles and the wobble would come back, but just not as violent as before the track bar was replaced. The Rough Country SS install now has a little wobble after going over a bump above 60mph, but I have only put about 10 miles on it to know if it will remain the same or deteriorate with time or miles. The vehicle is drivable so that is an improvement from when I had the very severe wobble. But it is not completely fixed. I think I will take it from here on my own. Jeep had failed to address it and the fact that a company would agree to purchase a part form the aftermarket on my recommendation to solve this issue tell me that my dealer wants to do what they can to please me, but Jeep has no real solution to implement and is leaving the dealers and customers to fend for themselves.

FCA has had multiple NHTSA recalls related to steering suspension issues on Ram 2500/3500 trucks that seem to be very similar in symptoms and repairs to the JLU ( tie rods ends,track bar,drag link,pitman arm). Is the engineering that hard or is it just cheaper to wait for NHTSA to force you to do the right thing? I think it was 6 model years on the ram before the issue was resolved.

*Don't own the JL yet....

Someone mentioned it earlier, is the trackbar on the JL seriously hollow?

Sure I agree, and people with stock setups should not have to put aftermarket steering components to be safe.
Also, obviously this is a step you take after going through the usual list of suspects (ie algnment, tire balance, mopar finger tight bolt technology)

However, new Mopar parts are appearing, and current speculation is there will be a recall or tsb shortly. People who have lifts, or not waiting for a new mopar part and having to convince dealer to install it, might want to fix sooner.
Big difference between a recall and tsb. There are already tabs out there for steering concerns. And if they actually did a recall it wouldn't cover any vehicle that has already been modified with other steering and suspension components.

The factory stuff is ridiculously undersized when compared to the yeti. My DW is 100% corrected. Shimmy is gone as well. I canā€™t recommend their stuff enough. If everything checks out with suspension components and things are installed correctly but you still have DW this stuff can make a huge difference.

Read another poster that had Yeti and Metalcloak parts and didn't help him. No one has an all-in-one solution.

Thatā€™s why I have been very careful to not state or imply this isnā€™t a guaranteed fix. I had a MC track bar. Itā€™s sitting on my shop bench. Nothing wrong with it but when I switched to yeti I wanted to have everything match. I sell someone local my MC track bar thatā€™s having issues with they factory one or needing an adjustable one for a great deal.

Did you end up backing down the caster a couple points?

No. Itā€™s still at 6.5/6.8. I put it on the lift yesterday because I noticed the shimmy was getting worse. Pulled the tires off an retorqued everything and installed the decorative caps. This is perfect now. The tie rod and drag link end had loosened slightly. The clamps were a bit loose after the alignment. Everything is tight and right. Iā€™ll drive it a week and check it again but Iā€™m sure itā€™ll be good now.

Worst part of installation was separating the drag link from the pitman arm. Going to get an air hammer with it. The other stuff just falls out.

I am experiencing the death wobble. It started about a month after I had the dealer install the 2" Mopar Lift on my 2018 JLUS and 33" BFG K02's. It started subtlety with shake in the wheel back and forth over bumps. It got worse until I experience the full on death wobble as in the video. I experienced that twice and had to come to an almost complete stop on the road for it to stop.

The dealer said the stabilizer shock was leaking and couldn't find anything else wrong so they replaced it under warranty. The wobble went away for a couple of weeks but it is back again and I have to go back and have them look at it again. Not sure why the dealer is trying to band aid with a stabilizer as I'm sure they know it will only mask the problem and will get the snot beat out of it over time. Maybe they will keep replacing them until the vehicle is out of warranty?

I'll see what they say on the second go around but if they give me the run around then I'll probably replace the steering components myself because I'm not going to run my Jeep that way if I can fix it - dealer or not.

Will do. I'm going to the dealer this week and will report back what comes of it.

99% of these DW reports are most likely due to geometry and alignment being FUBAR. I have had several wranglers, and have yet to experience DW. All have been lifted with quality parts and aligned regularly. Heck, my JK had a BDS lift and was still on all of the stock bars and bushings. I traded it in with 180K miles and never once experienced DW. It saw plenty of off-road duty as I survey gas lines and coal mines.

Having said all of that, most of these aftermarket parts, such as the Yeti offerings will improve ever aspect of the jeeps front end. These are far from perfect from the factory.
