So you’re going to adjust pinion angle over caster? You can’t dial in both. The more you lift the more they’ll be in opposition to each other. These axles like 6°+ of caster. You can’t have that AND ideal pinion angle. Caster is way more important in getting these things to drive correctly. The pinion/caster relationship is not the same as the JK.
Well yeah that’s how it works. Caster and pinion angle are a compromise. Set your caster where you want it, drive it and see how it works. If you get vibes you back off the caster till the vibes are gone. When you do a gear swap you do the process all over again as gear swaps greatly affect the drive shaft rotation speed. Pinion angle that was fine with factory gears may not be with 4.88 or 5.13 gears. No different then it was in the JK world, same base specs. Currently I have 5.5 degrees caster and no vides I’ve had it as high as 6.5 degrees. No issue with FAD locked at 50-60mph here. “Toe in” is also a factor as is front end geometry for the vehicle to drive and handle properly.
Is this true of the Rubicon X 4XE? The order guide indicates it had the DJV axle, but what about the HD front diff and steel knuckles? I know it has full time 4wd as an option.
Being a Rubicon X, If it has the 35” Tire package and 4.56 gears then it will have the heavier diff housing and steel knuckles.
That's great. But is it serviceable? You can't currently buy Rubicon differentials or locker actuators. I'm not buying another jeep if I can't buy the parts.
It’s all the same internals as regular Rubi on diff.
4xe Rubixon X is not on 35s and is not 4.56 gearing.
Which you can't buy...
You can buy the sensor now for a kidney, lol, (cheaper than the whole axle I guess) I’d imagine you’ll eventually be able to buy the actuator…….
Talked with a Dana Aftermarket sales rep a couple weeks ago. They said there is a issue with field servicing the electrical parts and that's why Jeep nor Dana sells them and that they have no plans to change that policy from what he knew.
So then it’s not a Rubicon X. It’s my understanding that all Rubicon X have the XR 35” tire package.
I’m sorry, but please go to Jeep.com and build a 4xe Rubicon X. It IS a Rubicon X, and on anything but a 4xe, that would include what was the XR package. The 4xe does not have 35s on the Rubicon X.
Well that’s sad … what does the X give you on a 4Xe that a regular Rubicon doesn’t have if you don’t get gears and 35” tires?
I think it's just steel bumpers and some interior enhancements.
