I just left the dealer an hour ago i had my stabilizer replaced two weeks ago they opened a new star case today and said another version is on its way should be in by the 24th supposedly has an air port in it tech wasn’t exactly sure what they was showed him all the tsb’s and star cases i could find i am gonna just end up throwing the synergy drag link and tie rods at it im guessing. Not sure what else i can do at this point not overly impressed with this thing
New update, dealership just called and was advised to replace my stabilizer as well. They said it will be out on the 22nd. They did the track bar, now waiting on the stabilizer. They can't release it until then, so it will be in this dealership for a month at least by the time I get it back. Since Feb when picking it up over 45 days.

Guys - just wanted to add I have been dealing with this issue for months. After several failed attempts at throwing OEM stabilizers on my jeep, I finally opened a star case where my dealership took more time and appropriate measures to correct the issue. They loosened my entire front end and retorqued to spec along with an alignment. Most importantly they also installed a new Fox stabilizer which vastly improved driveability and eliminated the DW. I think the biggest culprit here being either my upper or lower control bushings were loose.

However my steering still continues to be loose and wanders at times but most importantly I feel safe driving it now. I am trying to get the new track bar and bushings installed as part 2 of this to help with the sloppiness but I'm confident Jeep is on the right path here. Worse case is I will install a new Yeti or Rancho myself and take a chance at voiding my warranty.

What are your toe-in and caster alignment specs? Try your toe-in at the max in-spec range of 0.20 total toe-in. You can increase your caster by using the longer Mopar lower control arms from the lift kit sold separately.

This is an update to one that was published in November 2018.

Just a quick report from me that i just had this TSB procedure performed and my damper was replaced. Seems to have completey fixed my issue.. hope it stays this way. Very happy!

I took my JLUR into the dealer since my steering wheel shakes after hitting bumps in the roads at slower speeds. I have the Mopar lift which was installed by them which is the reason I choose this lift over other companies to keep the warranty. They are saying they will not replace the steering stabilizer due to the 37’s inch tires installed. They want to charge 330 to install the fox 2.0 stabilizer which I believe is only $170 part on Quadratec.

Now should I get the rough country dual steering stabilizer or should I choose another one to fix my issue? I wish I would have bought the RockKrawler lift and not this Mopar one. Please advise.
I'd stay away from rough country personally. Installed their shocks on my 35" tire silverado and it rode like a fng tank. Two years later both rear shocks were blown and one of the bushings had literally fallen out so the shock was flopping around on the bolt. I bought 4 shock extenders and four stock height KYB shocks - WORLD OF DIFFERENCE in ride quality. Those KYB's were not intended for a lifted vehicle with a 90 pound wheel/tire setup but have handled them just fine for years. Will never buy anything but hard parts from RC again. My 2 cents.

There is a new steering dampner coming soon they just implemented the fix last week so it will be a few weeks to get a parts supply stocked up

And the saga continues... today the FCA tech rep decided to have the HD Fox stabilizer on instead of waiting for the new Mopar one due it next week. Not sure why the change, but whatever the reason mine received the Fox unit now instead of the new Mopar one they said I was waiting on.

I'm all for a faster fix, but this one now seems to have a constant pull to the right. I did a quick search and seems a few others had this with Fox stabilizers also. I am hoping it will settle in as I use it more. It does seem to handle bumps better, so that is an improvement at least.

They did not replace my drag link end that was also loose, and also forgot to rotate my tires. But that is an easy enough fix on my own if I need to.

I got a new damper a short while back, which helped, then Tuesday they put a new drag link and drag link tie rod end on it and it is now where I wouldn't call it a problem anymore. I'm still going to install the Rancho track bar sitting in my garage. I'm betting it tightens things up even more. I still want to drive it a bit, but at this point I'd say the issue is resolved. The steering tracks great and does not wander.

I hope others are able to get theirs to a good place and can get back to enjoying these great machines.

I also just noticed today that since the mopar lift was installed it looks like my drag link is now at some unknown point making slight contact with the front splash shield

Add me to the count of people that get the shimmy right around 9k miles. Dealer could not get me in until 5/9. Not exactly happy as I have a road trip that I had to leave on this week. Now I'm driving 1600 miles on the interstate with a vehicle that wobbles every time I go over a bridge. I have to slow down to like 30 before it stops. This will be a joy.
