Any reports of issues with steering in the 2019s?

[jamesj242003]

Thx, just had my car at the dealer a week ago for an oil change. Didn't bother telling them about the useless navigation, would they automatically check for current updates?

I don’t know about your dealership, but mine volunteered the information to me and said it’d be a good idea to ensure that my system was fully up to date. One other thing—-I reduced the pressure on all four tires from 38/39 psi down to 36 psi yesterday. Very surprised, but no more drifting at all on the highway. My Jeep only has 138 miles on the odometer and still driving at 55 mph or less during the break-in period. I won’t know the vehicle drifting behavior above 55 mph until I complete the break-in cycle . Stay tuned.

I have 285/70 17 KO2s and did the chalk test. 33-34psi was where the chalk line disappeared uniformly. I now run my COLD tire pressure at 31-32psi so that when warm my tire pressure gets to 33-34.

I was skeptical that this would make such a difference, but it has helped tremendously. My wandering and dead center are resolved. Now I start lifting it. Best of luck to my fellow Jeepers.

I have to try this.

My JLUR (came out the factory on Feb. 19, 2019) steering is very precise with no dead spots or free play at all, but it does drift slightly both to the right and left.

My JLU Sport S was finished on 2/19/19 as well. Steering is tight and responsive, no issues for me either.

If anyone is having a wandering, overly sensitive, difficult to drive, twitchy, or other term, steering issue, they should read the post above about tire tread contact and pressures.

When a tire is overinflated, the tread is crowned and not in full contact with the road. As the vehicle is steered or driven on irregular surfaces, it shifts the weight and side loads the tires. This shifts the contact to the side of the tires and a small steering input results. When 4 tires are doing all this, it gets pretty difficult to predict the effect on the direction the vehicle will steer.

I'm not saying there are no issues with the steering system in these JLs or your particular JL. But putting the tires at the functionally correct pressure is a simple thing to do before you start chasing steering system problems. I've found 31-32 psi at warmed up operating temperature works well in my JLUR with the 285-70R17 K02.

There are some of us that believe the factory recommended pressure range was designated by FCA to help meet CAFE fuel consumption requirements.

Do you know what FCA’s recommended cold tire pressure is on 285-70R17 K02?

37 psi as per the door sticker

2019 Moab with KO2's and the steering is great after setting cold tire pressure to 32 psi and getting alignment done. After about 1500 miles the vehicle had a noticeable pull to the right before alignment. Now it tracks perfect at all speeds.

When I picked up my new JLUR on 4/12/19, tire pressures were set to 41. Even on the test drive with factory PSI, the steering wheel felt tight with zero noticeable play. The asphalt road wasn't the greatest because you could easily see and feel where the asphalt had sunk over the years from all the traffic (that typical asphalt tire tread hump) so I wasn't sure if the drifting I felt was because of the road or the tires. But when I got home, I lowered the cold PSI to 35 and it feels fine, just like my 16 Silverado I traded in.

A cold tire pressure for K02 tires being recommended on this thread ranges from 31 - 35 psi. At what point are K02 under-inflated, so tire starts to wear unevenly (more on the tire shoulder than crown)? “Jeepjunkie” conducted a chalk test and determined that 31-32 psi cold appears to wear the tire evenly. I have mine at 36 psi cold now, with no drifting any longer on the highway up to 55mph. It’s possible that when my speed exceeds 55mph, the drifting may return due to increased tire temperatures. Am trying to determine the optimal psi tire pressure where I do not get any drifting while optimizing my gas mileage.

Unfortunately, I can sympathize with everyones issues. I picked up an 18 JLUR last summer right around August or so. Was fine for the first 30-60 days and then the wobble started. Keep in mind was running KO2s on Mopar wheels, no lift and no suspension upgrades with mostly highway driving. 4-5 trips to the dealership and it's clear the steering stabilizer isn't the fix, it just masks whatever the actual issue is - and even with a new track bar, longer control arms, and new stabilizer all aftermarket the problem wasn't solved.

Knock on wood, I picked up my 19 JLUR last week after the 18 JLUR went back - so far has been really great. Even have 35x12.5x17 KM3s on it and is night and day from my 18. Wishing everyone luck with resolving the issues they're having.

I can't explain it, but I've seen it first hand and it's happened to friends of mine too. You buy a product like a car/truck and although they are supposed to all be built the same, someone gets a lemon that is prone to issues constantly. Why? No clue but for example, I had two uncles that both bought Fords (same model) from the same dealer ( a cousin) and one was always in the shop while the other was fine!

I don't want to jinx my Jeep, but so far so good and if past experience holds true, then I have a "good" one and I'll be alright.

Wishing you well on your second go around. Picked up my JLUR about the same time as your 2019 model. Hoping I do not encounter the wobble after a short period of time. The slight drifting that I had was resolved with input from JLWrangler forum members by reducing my tire pressure.
