dwindeck Most every jk will lean a bit (1/4") to the passenger side after a coil suspension lift. I'm wondering if the factory coils are slightly different to compensate for this. If you look, you will see that the engine, transmission, transfer case are all off center to the passenger side by at least two inches. Now add the fuel tank, skid and fuel and your adding x number of pounds, not a huge item but your 30+\- pound battery is also on that side. I weigh right at 200, so I used 200 pounds of weights and put some in the drivers seat and floor area, this changed it 1/8" so it still had 1/8" lean to the passenger side. So as the fuel goes down that side would raise although very minimal.

I'm sure different coil lifts from different manufactures will drive slightly different, and the shocks you choose will make a difference also. I am one, that does believe AEV when they say their coils and shocks are tuned to work as a pair. And that the testing they do, do to get it right is greater than others.

As far as your axle being off center and tires sticking out, they should be perfectly the same. I'm surprised at the amount of difference your seeing/saw. Use a straight object (4' level would be best), make sure all tires are aired to the same pressure, with the straight edge resting on the ground/floor, place the straight edge against the center of the tire/wheel and measure from a spot on the frame or coil bucket to the edge of the straight edge. Make sure your taking your measurement from the same spot on each side. I would do this front and rear, do it a couple of times to make sure where your measuring from, and to make sure what the measurement is. Anything less then 1/8" I would accept, anything more and I'd figure out why and have corrected.

Also, if you haven't, put it on an alignment rack. The machines (if the shop has the newest models) today can measure most every angle you could think of, and to very small amounts. They would also be able to tell you what additional parts you would need to make it perfect. Keeping in mind you can spend allot of money on things so the alignment specs look great, but you may not notice it, and you could drive a cross the street to an exact machine and it will read something different or around the block and back to the same machine and it will be different. He'll go sit in the seat while it's on the rack and the readings will change! But if your like me, just "THINKING" it's right make my jeep drive 100% better.

Good luck, and post up with any fixes!

GETN4LO Wanted to add my story to this thread in case it helps.
1. Got a 2013 10A Rubicon Unlimited in May
2. Within a week I had a 2.5" Rubicon Express Lift Kit installed and some 35" tires
3. I didn't notice the lean at all but then I was probably only looking at the height and tire size (which was awesome!) I attribute this lack of attention to be something akin to Beer Goggles.
4. Driving down the road one day, I noticed the lean. Probably more pronounced on the 10A Hood due to the molding.
5. Took it back to 4x4 shop. Here was their process.
- swap springs (no change)
- replace springs (no change)
- told me to live with it. (no change in my disappointment)
6. Took it back saying "I paid a lot of money and I want it right)
- They added a 3/4" spacer to the front right spring but it had little affect from what I could see.
7. took it back and said "there has to be something wrong still"
- The put a procomp adjustable track bar in as the front axel was sliding to the left too much. It was easy to see the driver side tires were sticking out from the fenders about 3" and the passenger side was only about 1" out.
- After the track bar was installed, the lean was down to less than 1". Better, but not right.
8. Over the last 5 months, it seems to have gotten worse. At least to a point where I notice it and every time I get in, I know it isn't right. Every wobble I think it is the lean. When I stop fast and the wheel wants to turn a bit, I think of the lean. I recently rotated all the tires to increase stability, nope...lean issue lingers over everything I do. I want to take it back in to the shop and see if the track bar needs adjusting again as it is back to being pulled to one side too much.

A buddy has a Teraflex Lift on his 10A and hasn't noticed anything yet in the 4 months he has owned it. I for one enjoy working and customizing my rig too much to let it slide and want it corrected prior to the Rubicon Trail trip in August. If anyone has any suggestions on either a replacement lift for the rubicon express kit or other options, please let me know. I just want it right.

I have the same springs and my 10A is dead nuts even side to side. What reference points are you measuring?

2five22 Once upon a time when the CJ ruled the planet and the Jeep had semi elliptical leaf springs, they all leaned on the drivers side. The more the driver weighed, the more the lean over time.
04-22-2014 11:33 AM
Cajun-in-tx Any advice here. I had a lift installed and I am noticing the same thing. I have my 1k post lift inspection at the shop that installed it and plan to ask them about it. I'm not sure if it was like this before the lift to not but I notice it now all the time.

I actually haven't made it out. I threw a tape measure on the front of the Jeep the morning I was supposed to head out and it was around 1/4inch lower on the passenger side now (versus the 1inch or so before).

I'm going to wait until Friday, measure it again, and then determine if I need to make the 1.5 hour trip out to the dealer.

01-23-2014 09:36 PM
mortuar Side note though - I thought my passenger front was sagging... but when I take a step back and look at it (and based on how it handles in turns), I think maybe the front driver's spring is too stiff. It sits with very little rake on the driver's side (almost looks like it has a leveling kit). Also seems more bouncy on that side when hitting bumps on the highway. I'll let them decide that at the dealership when I take it in, just wanted to share that thought.
01-23-2014 09:33 PM
mortuar I talked to the dealer where I purchased this 2014, and he put me in contact with the service manager at the dealership. I explained to him what I am seeing and he told me that's one of the most strange things he's ever heard of in regards to a brand new stock JK suspension.

I'm scheduled to take it in early Saturday morning (a 1.5hr drive) so they can stick it on their laser alignment machine. He told me there should be *zero* sag on any corner of the JK other than normal settling. He said this is indicative of a poorly wound spring, wrong spring, or spring not seated correctly in it's perch - and this is the first he's heard of it with a brand new stock/unmodified (now just about a week off the lot) Wrangler.

I'll let you guys know how the service appointment goes. I honestly don't see how sticking a puck on the side that sags to compensate really makes any sense. The suspension on a vehicle with less than 100 miles on it should be pretty square... I can't think of a single valid reason for it to be any other way. I've owned 4 previous JKU's (one X, one sport, two Rubicons) and none of them sat leaning like this. *shrug*

rmkscott My 10A has the same sag on the passenger side front. I installed a 2.5 coil lift and it's still 1" lower in the passenger front. The lift manufacturer even sent me new coils and it still is just lower on that corner. I Installed a 3/4" spacer yesterday and it helped so guess I will have to put a 1" spacer on that spring.
01-19-2014 09:27 AM
dwindeck Just looking at mine, I can't see the difference...but put a tape measure on it from a level surface to points on the frame and it's there.

dwindeck Most jk's will lean a bit on the passenger side. If you have ever looked, the engine, transmission, transfer case are off center to that side. Add the fuel tank and fuel
To that also. Mine and a friends with almost identical lifts bumpers ect. sit 1/4" low on the passenger side.

Your JK is saying LIFT ME! Please LIFT ME! give me a new suspension.

Measure the left and right coils from where they sit, up to the frame, to know how much its leaning. Then you can get spacers closer to the amount.
Anyone just swap the coils between passenger and driver sides to see if it evens out after a bit???
01-18-2014 02:06 AM
mortuar What ever happened with this OP? I just bought a new 2014 JKU Rubicon a day ago, it has ~140 miles on it now. Sags on the passenger side about an inch - and I'm at about 1/2 a tank of gas. It's super noticeable too - especially how the hood lines up (or doesn't, rather) with my garage when I park. I thought I had a tire that was going flat at first.

My rear fenders are identical heights off the ground. My passenger fender is about an inch lower from the ground - and it's super apparent when looking at the distance between the top of the tire and where the fender starts.

I've owned 4 JKUs prior to this... and never once had this issue.

I had a $62K 2005 Toyota Land Cruiser that leaned 1/2" ... I complained and that was their exact response, with the added statement "the specificaton is 0.5" lean tolerance."

I asked them for the engineering and assembly drawing that stated this specification. In the end I just laughed and cranked the front driver side torsion bar so the damn thing sat level.

If you look at mid-2000 Land Cruisers, you see this lean. I believe it's designed in help with front impact stats.

My 10A sits level side-to-side with my odd-ball 10A rear springs.

HK_Runner My 2012 leans a bit to the passenger side as well- .5"-.75".
06-09-2013 01:32 AM
m998dna Mine started at 22.5" at all four corners when brand new and the front settled in and lost .5".

The following is from my post on 4-22.....

Mine measures 22.0" front and 22.5" rear... center hub to bottom of fender lips.
