Loose steering feels like it has play and drifts

Congratulations. Take a look at 24.25 inch lower front control arms. That modification is arguably more impactful than the new steering box. It's a $60 DIY project.
In my ICON 2.5" suspension kit, these parts are already changed and the original steering was always catastrophic. Now with this new box it's finally normal, the reactions are exactly those of a vehicle with rigid axles (it's my third car of this type, raised and with bigger wheels, so I'm a bit used to how the behavior is on the road).

FCA had already changed my box for an "AE" ... which was always a disaster. Now with this second change for the successor of the "AA", so the "AB", I found a Jeep that should have been as it was when I bought it, especially for the selling price that was way too high...

So did you have an AA box and then an AB box? I was told there wasnt a difference (just different manufacturing areas, thus no updated TSB), but it seems like yours drove better?

There is no difference between the two except they changed a taper on the shaft to help in assembly. Every box ever made gets its final adjustment done by hand. There is a large “acceptable tolerance “ on the final over center adjustment. I have two of the AA boxes, and an AB box. Every one of them are adjusted different from the factory.I have had one of the AA boxes in the jeep and it drove so, so, the AB box is in the keep now and drives great.

Placebo is a thing.
Longer LCAs/positive caster makes the biggest difference in straight line stability.

My original box was changed for an "AE" while I had asked for an "AA", the problem was still very present, I saw strictly no improvement.

So I was forced to take a lawyer to get an "AA" (as clearly described in the service bulletin) and they changed it a few days ago for an "AB".

I have no information on the difference between "AA" to "AB" ... I only have a letter from FCA explaining that they will take the repair under warranty, and that the "AA" is now officially replaced by the "AB".

I can only say that this second change of box (original -> AE - > AB) has finally corrected the original serious problem

My ICON 2.5" kit had these two bars changed, and my steering was catastrophic. On fast road very dangerous and when crossing on narrow road, for example, also very dangerous.

Now the same car with an ICON kit, the bars changed and finally the new box, a test of 400 km make me notice that I can finally drive my car calmly, and without risking to deviate on the right or the left on the road.

2020 rubicon
Just had to chime in here , took our 2020 JL rubicon in for the Jeep “Wave” oil change and when we dropped it off we mentioned that it has always had a pull to the right issue and now at 11,000 miles it wanders consistently at all speeds ! Dropped it off at 7:30am Got a text that it was ready for pickup at 1:48 , when we got there the tech stated the oil change was done and they installed a new steering box and it will drive like a new vehicle!!! We were shocked!!!! I popped the hood and the aluminum(raw aluminum color) box was gone and it now has the black steel steering box and YES it is definitely a different vehicle!!!! I heard some of the horror stories about dealers not doing anything so I was prepared for a fight but all it took was a mention during a routine oil change and boom ....it’s done ✅. Very Happy here !!

You were really lucky, or just a very good dealer who serves his customers and is aware of the real dangerous problem.

I am happy for you

I've been waiting months for two different dealers to contact me and you take it in for an oil change and they knock it out???

@JeepCares I'm going to need you to contact some dealer in the Denver area to assist me. I'm getting nowhere with the ones I've been to. I actually have a fulltime job and fighting dealers over this TSB is becoming like a second one.

Bert, I can't tell from the description of the mods to your JLUR. Do you have longer front lower control arms?

Yep, front and rear. My alignment is spot on. I have a great mechanic who takes care of everything I need and the Jeep is *perfect* other than this sloppy steering gearbox. I plan to upgrade some other parts of my steering (rpm 2.5 ton and dynatrac balljoints but I’m in limbo until this crappy steering gear is replaced. I’ll have my mechanic do it if it continues into spring but have some long trips planned and I’m not driving it with 3” of play in the steering. I also have a fox ats stabilizer. If I decrease the stabilizer damping it’s downright dangerous to drive. That was my first ‘fix’ to make it drivable w/o being all over the road. I’m just tired of constantly correcting the steerinf and I’ve owned a lot of sfa vehicls so it’s not just my perception.

I hear you on that situation. The dealer I am getting my 392 from is so much more flexible than the large chain of dealerships that I bought my 18 Rubicon from. They were big enough not to care about anything other than the sale of the Jeep and didn't even care about the next person who was going to get it. It ended up going to a dealer in Comstock NY, and I left there with a Raptor that is an amazing truck, not a Jeep, but a truck so you can't even compare it to a Jeep. It should have some of the features available that the Raptor comes with, kinda makes you feel like your getting your money's worth. This is just my opinion based upon going through the same issue and thinking money thrown at it would fix what the dealer should have done. Sidenote, The electric steering pump was not retaining the pressure it required and was turning on and off due to a issue with the software which in turn caused it to drive perfectly fine o time and then be all over the road and have a serious death wobble
I would see if there is anyone here on the forum that has had positive results with a dealer in your area, it may be a pain to travel to another dealer but in the long run it may be worth it. There are some who have had to go that route to get positive results.
Or you can do like others have chose to do on this forum, and that is simply throw every dollar you have at the Jeep and hope one of them sticks to the problem OR it can be changed out under a TSP at no cost to you. the other option is to believe it is a "Jeep Thing " and have your $50k plus Jeep truly be a white knuckle drive every time you take it out on the street. You shouldn't have to be so stressed everytime that you take it out for a drive especially when there are thousands of other Jeeps out there not having any issues at all or the owners are simply not on any forum trying to get help in resolving the issue

Nope, I LOVE this Jeep and have it exactly how I want it now. It’s literally perfect other than the steering gearbox and it’s PROVEN that’s a problem by all the positive reviews on this forum after having it swapped out. It’s a problem with rhe dealers here in the Denver area. Customer service is non existent. The CO Facebook Jeep groups are littered with complaints about local dealers.

I have a long list of things I plan with this Jeep but need it replaced before I do. I’ll rip it all out and buy a PSC hydro setup if I have to. This Jeeps not going anywhere anytime soon. The problem is fixable but I shouldn’t have to pay $700 (or $400 for the part) to do it myself.

I may try another dealer but I can’t take days off work to drive hours all over the front range looking for a dealer that ‘might’ be sympathetic. I need to know one will actually order the part, not tell me they are, refuse to provide any kind of ‘receipt’ then say they don’t know what I’m talking about when I call for an update weeks later.

Once you (finally) get the steering box replaced you'll marvel at the handling. I have the new box, 25 3/8" LCAs, and a passthrough steering damper, and my JL steers like a dream.
