2015 JKU - ESC, TC, ABS, typical tom foolery
Little back info: I lifted the 2015 with an RK 2.5" kit on 35's. Everything was replaced except the arms are factory. Has been this way for a few months with zero issues, except the damn factory 3.21's were sucking.
Last week I decided to swap my 4.10 axles from the wrecked 07 into her (Terra44 front, stock rear). The Terra44 did take the impact on the passenger side, but everything I could do to check it all out showed me the axle was good to go.
And now I have traction control fuckery when taking off until about 20mph***. Seems to be the worst when turning right and taking off (like pulling out of driveway onto road). After the jeep gets above that 20-25mph shit the dash just yells FU, the ABS, Swerving light, and Hill Decent lights flash for a few seconds then go solid and she drives just fine. After driving for about 30 more seconds, the dash lights all turn off. Next stop sign I come to the process repeats.
I've recentered the axle with the adjustable RK track bar. I've recentered the wheel a few times with the Procal. Still no fix. In my 07 when I had a failed speed sensor I would get a code for implausible wheel speed input or something like that. Pulling codes now doesn't have anything like that.
For shits and giggles though, I replaced the 07 rear wheel speed sensors with the ones from the '15 rear axle but didn't have time to retest it last night. My buddy is bringing his SnapOn scan tool so we can monitor-live the system and see if we can't see an irradic wheel speed sensor.
Being that the front passenger side took the hit that totaled my 07 I'm betting that hub's tone ring is fuckered, or I may have damaged the sensor when swapping the axles.
*** when I start up from a stop and/or making a right turn from a stop (stoplight, stop sign, etc), the traction control will kick in and I can't move. After about 10 seconds or I make it to that 20-25mph mark the lights all kick in and I can drive again. If I'm making a left turn from a stop I don't have an issue the couple times I tried it.
Just about all threads on this subject where someone asks about pretty much the same shit is never followed up with a fix... so I don't have high hopes asking here, but figured it's worth a shot.
So other than what I've done, and what I'm planning to monitor tonight, is there any other suggestions on what to look for? Everything is torqued, everything is centered. Its completely centered around my swapping of axles so I'm pretty sure it has to be speed sensor related, the front ones just suck as they require swapping the unit bearings to fix that, so hopefully monitoring their signal will be a smoking gun.
