I recently installed RK 3.5 lift...the instructions give you dimensions of what to set all the arms up to but by doing that my axle was not centered so i decided to center the axle and not use their setting but now my airbag light is on and every time i go around a corner my rear axle locks and releases...i dont know if its the computer locking my breaks or the limited slip but the dash light up when its doing it with the traction control

Sounds like your steering wheel is not centered. Did you adjust the drag link?

i adjusted the drag link and centered the steering wheel

Did you put larger tires on or re gear? You might need an AEV procal or a programmer.

I also have the airbag light on, but it has nothing to do with the lift or axle position. I'm getting it into the dealer for a warranty repair because there is a fault in the electrical. My friend's 2010 also has this issue.

I'm running 37's....

but the problem goes away if i uncenter my axle

CJCAVITT

well i find it odd if i set my axle back up off center it goes out and only turns on when i center it.

When you uncenter the axle, are you adjusting the drag link? The JK computer is calibrated to a center point. When you add a lot of lift and the axle is really far off center and then you recenter the steering wheel, it is not recalibrating the computer. That is what the AEV procal will fix. Get it all aligned and then the procal will re calibrate the steering center. It really should be done on an alignment rack, but that is your call. The wheels need to be perfectly straight forward and then you adjust the drag link until the horn sounds. The steering is now calibrated.

I also have heard of quite a few people who have broken their clock spring by turning it to far one way when trying to adjust the wheel or while having the drag link disconnected usually if the wheel has been off centered by a half turn or more one way and you turn the wheel the shortest way to center it can make the wheel off one direction by one full turn so when you drive it and make a full turn the clock spring gets pushed too far and breaks if that makes sense

yes i adjust the drag link both when centered and uncentered...i had no idea the pro cal had anything to do with the steering, good to know. I havent had it aligned yet as i was wanting to figure this out before i went and did that but thanks great info...
