I also tried this. The rear springs can be swapped in twenty minutes. The TF spring retainers can be a bit of a pain. The fronts are a little more involved.

m998dna I wouldn't add spacers to level side-to-side. You can swap the springs left-to-right to determine if the spring rates are out of spec. My XJ was dead nuts even side-to-side stock.. the same with a Rancho 3" lift and then uneven after I installed a 5.25" Rubicon Express lift.

I believe this is induced by several factors and not an easy problem to resolve.

2014rubicon I asked this same question several months ago. My 2014 JKUR leaned to the passenger side when stock. now have the teraflex bb leveling kit.. still leans. I understand this is normal according to MANY fine Knowledgeable people on this forum.. and yes I assume it can be corrected by adding more spacers to the lower side but me personally I`m not going to the expense or trouble to correct a 1/2" to 3/4" of lean...

terrabit I've also ditched the shock extensions and added Rancho 9000xls ... and bumpers with tire carrier. Tried three sets of springs, not including the stockers. Still leans.

TF trackbar bracket in the rear, Metal Cloak trackbar in front. Axles centered. Deliberately relieved all pretension in the stock bushings including control arms. Did not change at all.

Could try preloading in the opposite direction: loosen up the bushing bolts, use hilift to raise passenger side then tighten bushing bolts. Ghetto level.

That effect is commonly overlooked... My XJ has an odd rear passenger side leaf spring that never settled right - pushes the front driver side coil down.

The spring with the higher rate wins.

terrabit After a bit of research I've concluded that this is normal. Most say it's the gas tank and/or associated armor, I can't say, but it is extremely common. The preferred method to correct it is with 1/2" spacers on the passenger side. If you're planning on changing bumpers, spare tire configuration or adding a winch you might want to do that first. I'm looking at adding a 1" spacer for the back right and 1/2" spacers for the front right and back left to even things out. You could conceivably end up with different spacers at all four corners.

ecor Hey guys I have a 2014 2dr 3" lift with fox shox, had the lift for 3months, everything when in smoothly didn't notice any lean but after 2 mild wheelin adventure, there is close to 1/2 sagg on the driver rear side, I notice everyone is having the right lean but I have the "left" lean it's pissin me off any ideas?
06-23-2013 12:28 AM
2five22 I recall when CJs routinely leaned on the left [driver's] side.

So while I think many stock JK's lean, adding components can make it more pronounced.
I'm using stock rubicon shocks with extensions. 3/4" is a lot, it's very obvious.

J33P4M3 may be reconsidering my TF 2.5 for a RK 2.5 afterall...
06-22-2013 10:30 PM
brianb What gets me is there is no lean on new factory jeeps, change out the suspension and it leans...
06-22-2013 10:20 PM
kjeeper10 Al I know is the Jk lean is nothing new.

m998dna Seems complicated.

Good question. Springratometer?

I've always wondered how springs were inspected for quality control other than for length.

They do have specs.. Not sure how springs are measured against those engineering specs during and after production.

Maybe Teraflex has the answer.

Barmanvarn Subscribed. Now I'm gonna have to go out and measure. Ugh.

So when the seat is unoccupied, or someone weighing 150lbs or below gets in, then the driver side ends up not sinking as low as planned.
The only problem with your theory is that the lean did not exist before the lift.

Also, I'm 46yo, 205lbs and built like an NFL running back, or so I'm told.

And the higher you go with good flex arms, springs and shocks, the more suspension travel and articulation... and that travel doesn't always settle even when parked - especially on uneven surfaces.

Hence the suspension is working its magic.

I would remove the spare and unloosen all of the upper and lower control arm bolts/nuts. Also make sure the springs are seated properly in the perches.

Make sure the isolators are the same size side-to-side.

m998dna Side-to-side my 10A sits perfectly level as measured. So if your Jeep is leaning side-to-side then my guess is something was assembled wrong or has defective or inferior parts.

The gas tank theory is simply BS IMO.... if that were the case then it should re-level when empty... stock or aftermarket.

legitposter Are we positive the JK, as in the frame, is actually lower on that corner? Has anyone measured the actual frame distance to the ground? I haven't... Maybe the JK's body is just mounted to the frame strangely, unevenly, and therefore a perfectly even suspension will result in the passenger corner appearing lower.

I don't know... All I know is the wrangler is a high vehicle so any lean is going to seem more pronounced. I'd imagine most vehicles are uneven when measured at the corners.

DCR-13JK I have a complete Rock Krawler suspension under my jk and I have the lean. I have taken everything off and put back on three times trying to figure it out to no avail. So my remedy was to buy a teraflex 1" spacer for the front passenger side. It arrived while I was at the beach on vacation so hopefully get it on this coming weekend. The lean makes me sick every time I see it.
06-22-2013 05:04 PM
J33P4M3 and everyone's raved about the Teraflex lift that I bought one, now these posts...
