So how did the total swap go? Did the all the new sensors work? Did they fix all the chaos that your jeep was having?

So I have some good news.

I swapped the front wheel speed sensor, used the JK one, which fits right in perfectly. The JL one has a green rubber ring.

Then I went on to check whether the wheel with JK sensor in, is reporting half the speed compared to the other wheels. BINGO - it does.

I had a spare JK rear wheel sensor, so tried to swap that, but apparently JL and JK rear wheel sensors are quite different, JK one is a lot bigger. But I figured it wouldn't be so hard to make the hole that the sensor is pushed through a bit bigger, since the rear wheel sensors are exposed anyway, unlike the front ones.

Here are some pictures how the look and where they mount into the axle.

I just ordered 4 new JK sensors and I will install them. I think this is going to be it. It makes total sense now why my traction control and transmission was going mental. Will keep you posted.

Hey, I am currently doing this swap and I ran into the rear speed sensor problem. I drilled a bigger hole for the sensors but it is still throwing my jeep into limp mode because of the rear speed sensors. Do you by any chance have any pictures of how your wheel speed sensor is sitting by the tone ring? Or a picture of how big of a hole you drilled? Maybe I'm doing something wrong but from what I read on this forum I did everything correctly.

I just completed a JLU swap to my 2013 JKU,, I followed your guide here and so far all worked perfect. Im having one issue. my flashcal from superchips that i have does not have the 3.45 gear ratio that i need for my new JLU axles.. what did you used to update your jeeps computer?

What did you use for the drag link? The end that goes into the pitman arm looks like it is a bit bigger.

Hey. Everything worked out just fine as described previously. I have been driving my JK with JL axles since then, zero issues whatsoever. No handling issues, no death wobble.

The only issue I have, which I have a solution for, just need some time to do it, is JL's OEM draglink and tie rod are very poor in terms of quality. It's very likely you you will run into this too.

Hi Viajab,
How are things with your JL axle install on your JK? From older posts the speed sensor swap cured electronics issues. What about the pitman arm and such? I'm looking at doing an aftermarket LL Dana 60 hybrid axle swap on my JK.
Would like some more feedback if possible.
