JLUR - right rear tire offset?

[JLscorpio31]

So I actually went back to my Jeep yesterday, loosened and tightened all the suspension bolts while it was on the ground. Then I had my wife push the body of the Jeep in the pass side from the driver's side. There's enough play in the eye of the track bar to move it a tad. Doing that gave me a difference of 1/8" to 1/4". Perhaps you could give that a try?

Otherwise, I don't see how the track bar would bidv your warranty? They would have to PROVE that the bar caused some kind of warranty issue that you were trying to get a claim on. Even that being said, you could have just reinstalled the OEM track bar before bringing it in for a claim. You're supposed to loosen it during the install process so I'm not even sure how they could confirm that you had an adjustable one or not anyway.

true, some or most people don't realize to tighten and torque the control arms after setting the jeep on the ground, this will most definitely affect your suspension stance/drive.

Update to the dreaded offset on my JLUR with MOPAR 2" lift - it took me a while to find the cash but just had the SteerSmart Yeti XD front and MetalCloak Durotrak Track Bar, Solid Chromoly, Rear adjustable track bars installed today. I know that some people believe that I was a bit OCD on this issue...cant blame them... I am. Some will also want to dispute what my initial driving impression is after only 100 miles having them on...but here it goes.

First the obvious....the body of the Jeep is now centered on the axles. That makes my eyes happy. Which in turn doesn't have me bitching about it in my head when I drive. More importantly I no longer have a 1.6 degree leftward thrust off the rear and i no longer have 2 degrees thrust offset to the right on the front. They spent some extra time dialing it in so I am pretty much zero on both.

The alignment is a huge difference in steering performance. Wandering has gone from miserable when passing a big rig on the freeway to the new norm of "didn't even notice it". I encountered the CA Inland Empire winds today for a few miles and this would normally have me in fits trying to keep the Jeep in the center of the lane and not look like I am drunk. Today, I got the occasional push from the side that I would expect from any gust of wind but the amount of effort to bring it back to center was not much more than any of my other cars so I would say at the moment that the adjustable track bars on a MOPAR 2" lift did more than just center the body on the axles...they allowed me to correct the crab crawl so I can drive like a semi normal OCD person that I am.

Now....believe me it still drives like a JEEP. But now drives the way it did before I had the lift and I love it.

Ok i noticed im having the same issue on my 19 JLU. My rear driver side tire sticks out further from my rear passenger side tire. If it matters, unlike most on this thread, my Jeep is still stock height but with 33 inch A/T tires. Any suggestions?

Lift will shift both front and rear to the drivers side without adjusting the track bar length.

So NO lift kit and 33 inch tires will throw the rear off a bit?

No lift and 33's should not be an issue. its the lift that causes the problem. If you are offset with no lift and 33's you will want to find out the thrust angles front and rear and make sure the alignment is spot on. If you are using after market rims, measure the offset in the rims to make sure there is not a defect there. 4 wheel alignment with thrust vector will tell you if you are out of spec. I you are...then your dealer will need to get you back into spec....might mean an adjustable track bar. Your will also need to take consistent photos of right and left side to prove the shift has is present. Once you can document it....they have no choice but to fix. it. DM me and I can tell you what I had to go through to get mine fixed.

This is crazy. All this just because of slightly bigger tires? Man i wish i new all this before i bought the Jeep. I would have just kept my Mustang.

Anyway, ive only had it less than 2 months. Everything is still stock except for the 33s. I still baby it. Havent even done any minor offroading yet. My alignment seems fine while driving. Not sure why thrust angles and alignment would be out. Not sure why any of these problems would exist. Except maybe a wheel defect. IDK, Then again im coming from a 2016 and 2019 Mustang GTs. Im used to muscle cars, not 4x4s. This is my first one, so im clueless.

I had the same problem moving from sports cars to a JEEP but the unique solid axil and the way the body is attached to the suspension takes a bit of getting used. The axels will shift, can shift, and can be just off when new/received. They can be off a little to as much as 1/2" to either side and be almost in spec.

Due to the geometry of the suspension shifting the axels in a direction will change the Thrust Vector since the pivot point of the axel is not in the center of the suspension. When you shift the axel the axel will shift one wheel forward and the other wheel back...this angle is the thrust angle. So by measuring the thrust angle you can determine if your axel is out of alignment. There is no adjustment for this without a new track bar Lifts will cause the front to go one way and the rear to go the opposite...making things just crazy to deal with...thank goodness for adjustable track bars to correct this issue.

33" tires are stock on JLURs...which one did you get?

I have a 19 JLU Sport S

Ok...I think I would try some of the early advise. If you changed the tires...there is a chance your body may have just shifted on the suspension from just being up in the air. So good time to go back and make sure the suspsension is tight. Might want to just lossent it up and shove the suspension in the direction you want it to go and then tighten things up. Put the JEEP back on the ground and see what you get. According to what you are saying is the only thing you did was upgrade tire size. The tires themselves are not going to have any affect but the lifting of the JEEP and setting it back down if the suspension to body was loose could. Worth a shot.

Tires don't change the geometry as it only raise the axle line from the ground plane.
Lift changes the axle relative to the chassis and the horizontally fixed track bar is not adjustable and will pull the axle off center.

Ok i went to a dealership today and had my alignment specs checked. They said all my numbers are good in spec and the rear doesnt adjust.

Well you didn't change anything on the suspension. Why wouldn't it be in spec?

Eliminating causes why some tires are sticking out further than the others
