Caster Angle Off

2506 13
Put my RK lift on this weekend and got it aligned today. They said the caster angle is off and even if I adjust the LCA's all the way down they will still be off. Best way to correct it with AEV Geometry correction?

If an alignment shop doesn't know that they can get adjustable ball joint sleeves for it I would find another alignment shop. Adjusting the caster with LCAs changes the driveshaft angle. You should set the driveshaft angle with the LCAs, and set the caster with balljoint sleeves. If the sleeves won't get you enough then you can get the rest with LCAs.

huh,

wtf is a ball joint sleeve?

never heard of it.
It's a sleeve that installs around the balljoint that allows you to change the steering axis in relation to the axle housing. It may just be an offcenter balljoint for the JK instead of a sleeve. Either way, it's out there.

the best way to get caster back is to install adjustable front lower control arms. there really isnt a better way.
No, the cheapest and easiest way to adjust it is with LCAs. The best is with balljoints.

If I remember correctly the offset balljoint is to adjust the camber not the caster. The caster setting for a lifted Jeep is different than the stock specs, what degree angle is he trying to adjust it to?
They can adjust either of them or both depending on what offset you get and which direction they are installed.

If you're at +6.6 and the pinion angle is OK I would call it a day. That's a ton of caster.

Hey JMC, you installed the RK 2.5" MT lift, yes? Same as me?

I set my LCA per the RK instructions. I had mine aligned at the dealership and they didn't mention anything to me about not being able to align it properly. My steering wheel is a little soft and I get some slight wandering on the road, but it's nothing I didn't expect going up to a 35" tire. Just by looking under my Jeep I can tell my pinion angle has changed (obviously) but it's driving just fine so far.

Correct, offset ball joints correct Camber, LCA's can adjust Caster. Just did the offset upper ball joints today, along with replacing the lowers.
