This issue just presented itself about 4 months ago with our 2019 JLU Sahara, with only 15000 miles on it I’m very upset to hear that low speed clunking coming from out backGetting louder and louder.Just opened up a case with FCA and sent JeepCares a DM. Also have a appointment with the dealer on the 29th

With everything that is going on with the Dana LSD axles, I’m getting pretty leery of them. At this point, I’m just not confident that their ever going to be any good. I’ve been waiting for a month for mine to be fixed, but I’m thinking I’m just going to Dana 44’s or Dana 60’s with ARB Lockers and call it done.
Rubicon take-offs?

My question to anyone able to chime in, Is the sound our Rear diff makes is LOUDER with our 1.5” wheel spacers on.
Anyone else experience this issue??

Just read the post, what I’m concerned with is if I Remove the spacers but then put wider wheels on later down the road, will the sound return?
I’m guessing the extra width and strain on the axle and bearings is what’s making the noise. Which is complete bullshit....
Not sure about the noise coming back, but I would be concerned if it has damage that remains after they are removed but you cannot hear it until it is close to total failure. I agree that if spacers cause damage/problems that easily the axle design is total crap.

I might just suck it up and change the whole carrier to an ARB or Detroit unit when we do the re-gear down to 4.88 and never worry about it again.

As of now the only option out is the ARB. or mopar replacement. I've had 3 shops check on other options.

I totally agree on this. I’ve researched it, spoke with my off-road shop and a couple of Jeep gurus and doing away with the LSD and going with ARB Lockers is the way to go. I’m going with ARB, but I do wish Eaton had E-Lockers for the JL.

I’d love to do Detroit E-Lockers and just put the factory locker switches to them, but I like the idea of an ARB for the multi uses of the compressors
It’s just ANOTHER $500+ on TOP of $1k not including the front and rear Gears

Absolutely, I would go E-Lockers if I could, but doing an axle swap, re-gearing and adding ARB Lockers and Compressor will put me around $23K, but it will get me a way from the LSD and solve my issue with the rear axle noise.

I have the same concern about putting on wide wheels.

I've been trying to get a decent recording of the sound with the spacers on, then I'll try for another recording without the spacers. I'm not convinced removing the spacers makes the problem go away completely.

The shop that did my lift/tires/spacers is stumped. They hear the noise while driving but don't know what the issue is. There is no noise if they put the Jeep on a lift and turn the wheels.

Well, I’ll see what my dealership does to remedy the solution.
They’ll probably say they aren’t required to do anything BECAUSE we lifted it.
Which has no way in the slightest of effecting the rear diff.
Which is why I’m going in, and not my wife, mainly because I understand the mechanics of it.

I've got just shy of 23k on the clock on my '18 sport with LSD rear. Just noticed the knock a few days ago and quickly found this thread. I heard back from JeepCares here via PM today and called the dealer. It goes in next Monday, so we'll see what happens.

I do have a 2.5" lift, 35s and 1.75" wheel spacers so we'll see how mod friendly my dealer is (they installed the 35s on stock wheels at time of purchase).
