I talked to a Dodge technician earlier today and he said there's a place in the PCM entry which must be updated when changing the axle ratio. This is important as it will affect some engine set points and the ABS computer. They've done a couple at his dealership. He doesn't believe you'd get a problem code if you didn't update the computer.
NOTE: If you have a 2012 you may have a ZF axle.
There's a ring and pinion kit for the Chrysler-built axle (05015371AE
) that includes a new pinion seal (68056356AA
), a front pinion bearing (05072498AA
