'16 JKU not level L to R

In 2017 I bought a new overstock 2016 JKUR. After owning it several months I noticed that the passenger side is about 1/2" lower than the driver's side when measured at the same places. For example from the same place on the front fender, or even to the frame where the front control arms mount.

I know it's not an issue with the stock springs as I recently swapped them out for a set of new JKUR Recon springs and while it came up about 1.5" the passenger side is still lower by 1/2".

Is this typical? If so is it by design? I can imagine that having only a driver on-board would level things out (I did not test this yet). If not by design, can I adjust or "fix" this? Being OCD this bugs me.

Apart from the JKUR still not being level, I can recommend the Recon springs for those wanting a little more height without wanting a full lift kit. My wife didn't even notice the change, so that's a win in itself.

Passenger side is gas tank. This is typical.

Normal, I have heard it referred to as the "JK lean" on the forums.

Its normal, but still dumb, and not the tank. Run yours empty and it'll still lean. I fixed mine by dialing in some preload on my adjustable swaybar links. Some guys use spacers.

Or, if you are one of these people who names their junk, call yours "Eileen".

Thanks for your replies. I'm going to take a few measurements to figure out the amount of lean F/R, and then order the appropriate levelling spacers to square it up.

Fix it so it sits level as soon as you get in it now it will lean left. A full tank of gas adds 114 lbs to your vehicle. Your rear door and spare tire weight are also carried on the right hinges of the vehicle, that is easily another 100 lbs. The right side of the Jeep always carrying more weight.

This is driving me nuts too. I’ve got nearly 3/4” difference (Right hand drive Jeep) after fitting TeraFlex levelling spring kit. I’m going to fit a 1/2” spacer on the rear coil and see if I can get closer.

Mine is 1/8" lower passenger side, but many cars I owned where 1/16-1/8 lower on one side.
I think is to compensate drivers weight, 185lb (x0.75) of gas on the right side + 50lb battery and roughly the same in driver seat on the left.

It is common. There are different theories as to why it leans, the gas tank being on the passenger side is one and some seem to think it has to do with the spare tire being attached through the tail gate hinges. It may have something to do with the simple track bar suspension. Whatever it is, it is common. And if it bothers you spacers should be able to fix it.

Does your RHD model still lean to the right?

Do a more methodical measurement. Remove an end link from the sway bar (or with a Rubicon, electronically disconnect it. Now put a jack under the rear diff and lift it enough to get the rear tires off the ground. Now measure. If it's exactly the same, something else is causing the lean. Is your front sway bar bent? (mine is). Is there a spring not set in the rear? (I had that when I put in a Terraflex spring spacer) Is the rear sway bar bent? There's lots of places for things to go wrong.

If things are still leaning, check that the front springs are in the end capture on the axle. If everything looks right, I suppose you could go to a race shop and do this with scales under both front tires to see if there's some huge difference. And/or swap front springs side to side to see if that changes things. Oh....look at the front spring tags. Are they the same number?

Yes it does.
With a RHD Jeep, it’s quite different underneath too. Trackbars are flipped in the other direction too, which makes me think it’s not the cause.

When I levelled my old TJ, I noticed that you have to think about levelling them diagonally, corner to corner. A spacer on the rear driver side (positive) also affected the front passenger (negative). I’ve got one front and one rear spacer bought but it’s just a bit of a pain to pull the thing apart on my driveway again!
