This post supports your findings as well - https://www.jlwranglerforums.com/forum/threads/how-to-dial-in-your-steering.22188/I actually have something good to post about the wandering and loose steering. I'm just posting my experience with this issue and what I did. I'm not saying this will be the same for others, but it is something to consider.
I adjusted the toe-in yesterday and put 60 miles on it since and I can tell you that I'm very happy with the results, compared to how it drove before. Having increased the toe-in, it now tracks straight, therefore the seesawing action is diminished greatly! I took it on the Interstate for a quick test ride, but it drove so good that I did a complete loop around the city. Then this morning, I thought I would adjust it slightly more to feel the difference. I then drove through two lane back roads where I would normally have to be very cautious. It felt great!
On my Jeep, there was this phenomenon where it was tracking slightly left or to the right. That's where the seesawing came into play. This is now gone.
Here's what I did.
Jack up the front, under the pumpkin, just enough where the left front wheel is off the ground. The pumpkin is off center, therefore this side will come off the ground first.
Then, I took a marker and marked the position of the locking nut on the bracket. This will allow you to lock it back in place at the same spot.
Then, I marked the original toe-in position. Make sure you mark the tube and thread. The bracket moves freely once loose. Here, I already moved it slightly inward. This was yesterday.
This is the current position. I don't know if this is too much, but it's something I'll have to keep in eye on as far as the tire wear.
So, this is where I'm at with the loose/wandering steering. Dealer would not apply TSB/even though mine fell within build date, said it was normal for the JL. Have been waiting for a fix as many of us have and pretty much gave up. Thought I'd share my experience with others who might want to try this. The key take away here for me, is that I feel I have control.
Did you measure at all?I made an attempt at adding a little toe-in today to reduce the wandering at highway speeds, haven't been able to test drive yet because life, but i will ASAP.
for those of you who actually know what you're doing (unlike me), is this much adjustment considered to be a "hair" (as recommended in this forum) or a huge amount that will adversely impact handling / tire life? the white paint marks were aligned before i made the adjustment. thanks!
no, I didn't. I know that's the proper way to do it but i didn't have time today. I'll drive it tomorrow and if it feels any better then I'll measure it and decide whether to keep it where it is or return it to where I started.
you are a machine! i understand it's just a rough estimate but thank you for taking time to think through the math.
Hey all. I keep seeing post for finding a way to fix the tracking and loose steering. I tried everything and ended up with all items back to stock and getting the steering box replaced. Amazing result from new steering box and reflash. It's a totally different ride. Jeep knows there is an issue and all you have to do is have your service tech send jeep a case study and they will comply. Many JL owners are following this fix and loving there jeep. I was the first at our dealership last month and many have been fixed since then. Once your dealer has a fix they can push everyone through.
I'm not sure what the version was but my build date was 4/18. I'm being told that it doesn't matter the build date because the band new parts and jeeps are bad have to be tested and sent back if they don't meet the test. There is a torque rotation test that the dealer performs on the installed box and all new sent parts.
Yes there is a Star case for prior 5/18 build but others are using that case to get 2019 issues fixed as well. Jeep knows there is a problem, they just need pushed. I will check with my dealer tomorrow for any newer cases as I know they had several late models looked at.
