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 09:30 PM
brianb What gets me is there is no lean on new factory jeeps, change out the suspension and it leans...
06-22-2013 09:20 PM
kjeeper10 Al I know is the Jk lean is nothing new.

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 04:04 PM
J33P4M3 and everyone's raved about the Teraflex lift that I bought one, now these posts...

legitposter My JKU's front passenger corner sits noticeably lower than the driver's side. Though I have tiny 3/4" coil spacers installed, I don't think that caused it. It just plain leans. I've checked the stock spring part numbers for each side and they're the same. It just leans.

So yeah, it sort of just is the 'JK Lean' in my case.

Left Lean after TF Coil Lift

I recently installed a 2.5" TF coil lift on my 13' JKUR. Since the installation it has leaned toward the passenger side, the driver side is about 3/4" higher than the passenger side. I called TF support and spoke to a tech who described this as the "JK lean". It sounded like canned response he'd given hundreds of times. Funny, my JK didn't lean before the lift.

Anyway, per the installation guide, I torqued the control arm bolts while the vehicle was at ride height, meaning I lowered it to the ground and rolled it back and forth to relieve any binding. One thing I did not do is remove my 110lb spare - and the gate may have been open. this would have placed an extra load in the right rear corner. I have a suspicion that these conditions could have contributed to a lean.

If this be the case, simply loosening and retorqueing the control arm bolts could provide a remedy. I have two questions:

Does this sound feasible?

Which control arm bolts would be affected, inner, outer, both?

Thanks!
