Updated front trackbar with stiffer bushings coming to help cure STEERING issues 68394087AA

Exactly. These factory alignment angles are not unique to the JL. They are founded in 100 years of producing millions of vehicles. What is it that people believe are novel or unique in design features in the JL that would be cause for different alignment geometry? I believe nothing is unique in our suspension or steering design that would warrant different alignment geometry.

I'm of the belief these issues are all about the details of the design, such as joint integrity, bushing spring rates, stiffness of steering links, stiffness of the Panhard (track) bar, etc..

solid axles were mostly leaf spring designs other than fairly recently. The 70s ford bronco had springs and we used to make fun of its wacky design. I remember one writer of a 4x4 mag (what read read pre-internet for yuou young guys :P) claimed coil springs are only good for pogo sticks.

But in any event, ya the stock suspension appears to mostly need a lilttle thicker tubing (no it does not need to be solod for most people), and better bushing. Everything has a quality yield, and the bushing appear to be way under a reasonable point.

90% in school gets you an A, on mass product its an F as you end up with 1000s of angry customers (this is one of the first things I teach young engineers out of school)

I am experiencing the exact issues laid out in this star case but have a January 2019 build date, so my dealer would not cooperate and even investigate the toe or explore replacement parts. (My build date was outside the range covered in the tsb, but built prior to this release. They also ignored that a new track bar should be available). This was my 2nd attempt with this dealer.

First attempt, I called with roughly 600 miles on the odometer was told that an FCA wide mandate is that you need 1000 miles on a vehicle for the suspension to break-in before they could look at anything. Not sure if anyone heard this before.

I just bought a leftover 18 JLU this past weekend and it had a ton of play in the steering and is sketchy on the freeway. I took it in and they replaced the track bar after finding a TSB. It fixed the slop to the right only, still two or more inches of play to the left.

I’m trying to wrap my head around how steering play could be isolated to one side only.

Not sure, it only becomes really obvious above 55 or so

broken steering stabilizer can do it, as a wild guess I would think steering stabilzier has a physical issue + another part like drag link has mush.

I brought my Jeep to the dealer for another issue at two weeks/500 miles. The steering isn’t good and they checked the components and did an alignment. They didn’t bat at eye at the low miles regarding suspension.

So I've put maybe 400 miles on the updated trackbar and steering stabilizer on my sport s. No lift. Death wobble is minimized but I still get some of what I call front wheel hop on big expansion joints. Jeep hops a bit to the right.

I am sorry to hear you're having such a tough time, n1vek. Are you thinking about working with another dealer? Either way, I can escalate a case who'll help communicate your concerns and work toward a solution for what you're experiencing. Send me a direct message if this is something you might be interested in.

I call BS, it’s happening to Jeep’s right off the lot with miles in the single digits.

I still have not had a single instance of DW with my 2019 Rubi. 5,400 miles on it so far. about 500 of those miles have been solidly off-road due to my job. I keep the alignment in check and tires are at 35psi cold.

I just bought a 2019 JLU Rubicon this past Saturday. I drove home (about an hour) and it was like driving a 1970 Lincoln on the Interstate. I thought it was because of the wind. I have since driven with no wind and whether going 40 mph or 60mph it is a full time job keeping it in my lane. It is constant corrections and not little ones. I have play in the wheel. I love the Jeep but hate the steering issue. I had a 2012 JKU Rubicon and it was nothing like this. Calling the dealership tomorrow after reading ALL of this info. Also sent a PM to Jeep Cares.

Something is not right. Mine cruises nice and straight, and only during wind gusts do I really have to fight with it.

Crossposting from another thread, but I took a video of the input/output for my steering box.

Does this look like excessive play? How does this compare to other users.



Edit: Corrected privacy on the video.

I was the same at that mileage. My steering wheel shimmy didn't start unitl about 7000 miles, so hopefully you stay solid.
