| Total Toe** | Caster | Cross Caster* | Camber - Left | Camber - Right | Cross Camber*
Sport | 0.20° +/- 0.20° | 5.35° +/- 1.00° | 0.00° +/- 0.50° | -0.25° +/- 0.50° | -0.25° +/- 0.50° | 0.00° +/- 0.50°
Sahara | 0.20° +/- 0.20° | 5.05° +/- 1.00° | 0.00° +/- 0.50° | -0.25° +/- 0.50° | -0.25° +/- 0.50° | 0.00° +/- 0.50°
Rubicon and 3.0L Diesel Sport / Sahara | 0.20° +/- 0.20° | 4.80° +/- 1.00° | 0.00° +/- 0.50° | -0.25° +/- 0.50° | -0.25° +/- 0.50° | 0.00° +/- 0.50°
Note: Caster values required to be greater than or equal to 4.0° for all variants
* Cross Alignment values are determined by taking the left side value minus the right side value.
** TOTAL TOE is the sum of both left and right wheel toe setting. TOTAL TOE must be equally split between each wheel on the same axle to ensure the steering wheel is centered after setting toe. Positive toe-in and negative toe is toe-out.

Just food for thought, with a 2-4” lift run as must caster as you can without vibration (5-6 degrees, there will be a sweet spot) with adjustable lower front control arms to get a better street manners. I recommend getting lower adjustable control arms with the mopar lift, it makes a big different getting another 1/2 to 1 degree. When I install these at the dealership I only do them with adjustable lower arms. Also if you don’t use 4hi on snowy street roads or for whatever reason vibration might not be an issue because unlike the JK the JL front driveshaft doesn’t spin in 2wd with the CAD.

What adjustable lowers are you using with the Mopar lifts that you install?

I normally use Rock Krawler front lowers. I like their arms and customer service for the price.
I heard rough country makes adjustable camber bolts you can use on the mopar lower control arms as well

So is the JL axle the same setup as a JK. 6 degrees at the ball joints with 90 degrees on the axle flat spots?

From all the data that I've seen it appears the Caster for Rubicons seems to be in the 4.0 range (not much higher), and the Sport much closer to 6. So although the listed spec for Rubicon is 4.8 +/- 1 and the Sport is 5.35 +/- 1 the REAL difference in stock Caster is much more than 0.55, it's much closer to 1.5 to 2 degrees.

For Rubicons running stock suspension (and plan to keep the suspension stock) the longer Mopar LCAs (from the 2" Mopar lift) will put your Caster up in the Sport range to provide much better on road tracking w/ much less chance of wander.
Also if you lift your sport 1.5 to 2" the longer LCAs will restore your proper stock Caster set.

Does the Willys have the same specs as the Sport?

Did you ever get an answer to this? What specs do the Moabs follow?
No - haven’t seen a reply just yet. I’ve heard some informal yes, no, and in between, but nothing I would consider definitive yet.

Just an FYI the castor I found to get rid of all the shimmy in my steering wheels on bumps was around 7 degrees...the JLs love castor and the rubicons are terribly anemic stock. Add a littel spacer lift and it gets way worse...its the reason a lot of people get "death wobble" on stock JLs sometimes...I use some Teraflex alpine lower adjustable control arms because they use factory style clevite bushings and not flex joints...zero maintenance and no rattle or wobble over time.

This may be a dumb question but you like 7 degrees of positive caster? And I believe that if the flat spot at the axle is 90 degrees, then you have 6 degrees caster. So you bring it in one more degree? I ask because I am getting a lot of feedback coming from my steering.
