A code for the right front sensor was shown at Oreillys. Is that the wire running behind the rotor then up the side of the wheel well?

Yes ,that's where it runs . You might as well change the hub assembly as you were hearing noises when turning left . this makes sense too because the right bearing would load up on a left turn .The new assembly will come complete with a sensor .

Is there a keeper of some sort that holds the actual sensor in the hub? I've got everything off and the Allen screw. Soaking it with some pb blaster now. Is it just a careful twist and pull?

There's nothing descriptive in the Service manual besides undo the nut and remove the sensor. I've never actually taken one out though .
I find it easier to change the whole hub .If your hearing any grinding , howling squeeling type noises , your probably going to have to change it sooner or later anyways .

It is a tight space to get the sensor out. Alot of times the old sensor is broken in the process of getting it out but you will just have to take your time and wiggle the new on in and into place. I know some people have filed the plasitc housing down a little on the new sensor to squeeze it in.

I broke it then drilled the old one out. Only had 4 in the state. Luckily two were in Little Rock. Going to get it now.

Hopefully this'll get me going again and my 4wd Low will come back on. If not I'll take it to the dealer to redo the flash for the recall. Got my fingers crossed this works.

Installed a new sensor and the light hasn't came back on again. Haven't drove but a few miles. 4wd low still doesn't work so I'll be going back to the dealer so they can fix that issue.

Where did you buy the sensor from? I need to replace my right rear sensor. Glad to hear the lights went off. How far have you driven it? Sometimes it takes a little drive for all the lights and messages to clear.

I ended up getting the same exact sensor with a Chrysler stamp on it from AutoZone in a Duralast box for $29.99 with lifetime warranty. I know on mine the fronts are the same but rears are different. Rears were only $15.99 at O'Reillys and AutoZone. I haven't driven but a couple miles. Came back and tried to engage the 4wd low in Neutral but it still said to service 4wd system. Taking it to get reflashed tomorrow at dealership.

Ill have to call the autozone up the road and see if they have any in stock. I've been too lazy lately since the lights only come on every so often. Still pull the code U1418 even with no lights or messages.

Its easy work for sure. Luckily they don't cost too much. The fronts are higher than the rears but not too bad. The auto zone duralast auto zone part was exactly the same as the original other then the part number ended in D instead of B.
The part number for the front is a (Duralast)SU8584. They are the same for the front. Not sire what the rears are.......yet

That seemed to do the trick for the brake message. Put 40 miles on it and no lights came up. I'm sure I'm just dreaming but I reset my avg mpgs, which I don't trust too much, but it was saying 23.5 at 2000 rpms going down the interstate today. I've never seen it say that. It usually says 15-17 avg mpgs. I hope I'm not dreaming and it'll change for real.

I was driving down the highway yesterday and all of a sudden it sounded like my axel broke into a million pieces. The DTC code was U1418 and a noise was coming from the right rear, I took the old one out and the noise was instantly gone. Put the new sensor in today and the code keeps coming back after multiple clears with the programmer. I've unhooked the sensor still no luck. Says check electronic break system and service 4wd.
