LSD or No LSD?

LSD is redundant, Brake Lock Differential does what it does but better.

I'd keep what you have, especially with things @alphawolff has mentioned about build quality of the '24's. Your Jeep is still practically new.

This statement looks/sounds like a guy trying to convince himself. I‘ve had the trac-lok LSD on numerous Jeeps and the one on the JL is just as good and performs as solidly as the previous ones did. Never experienced a problem with none of them.

There's a 112-page thread of people having problems with the Trac-Loc destroying their axles: https://www.jlwranglerforums.com/forum/threads/knock-in-rear-with-dana-44.16921/

The trails looook soooo beautiful with LSD. Oh wait, wrong LSD.

I say skip the LSD and go for the magic mushrooms

I am considering a trade of my '21 2-door Sport with LSD for a 2024 2-door Sport... I might just keep my '21, which has zero issues and only 13K miles on the 3.6L...

Given current build quality and the fact that you have no issues w/ yours, I would ABSOLUTELY NOT trade it away.

And you don't realize how much you use & like LSD until you suddenly don't have it.

LSD is redundant, Brake Lock Differential does what it does but better.

I can tell you the difference is night and day between the two. My JK came with LSD, ya I love those for a long time, and the day it quit on me I notice it. When you need traction in snow LSD just make sure the power is split, BLD try to move power around until something grip. One deliver right now the other fumble around until something work.

I am considering a trade of my '21 2-door Sport with LSD for a 2024 2-door Sport. Unfortunately, LSD is no longer an option, so I'm thinking that I might just keep my '21, which has zero issues and only 13K miles on the 3.6L. I do venture off road fairly often, usually overlanding/trails on flat and hilly desert, and often with loose gravel and sand. I don't always need the LSD, but it's nice to have when you need it. However, I've read that the stock LSD config on the JL is apparently prone to failure.

Given my use case, I'm leaning towards keeping my '21, but just curious what you all would do in this situation.

To what extent have you used, and what is your opinion of, the Brake Lock Differential feature? You'd still have that one pinch hitting for the now-absent LSD in the '24.

To be clear, LSD > BLD.

This.

The JL axles have no carrier break. All ratios work with a single carrier. The JL axles have a much more narrow range of gear ratios to support (3.45-5.38) than the old Dana 44 (2.73-5.89). Those really tall ratios in the 44 need a huge pinion head which means you have to move the ring gear out quite a ways.

As far as swapping in a limited slip, I'd still go with shorter gears like 4.10 if I were going to all that trouble.

Is this true for the Dana 35 as well or only for the Dana 44?

All JL axles. M186 (d30) and M210 (d44) front, M200 (d35) and M220 (d44) rear.

I can for once offer some first-hand experience (feel free to draw your own conclusions, of course):

• Installed f/r truetracs and regeared my Sahara about a year ago (maybe two?)
• Couple weekends back I attended an offroad bootcamp class and there was a non-LSD stock sport. They took advantage of the different vehicles (4Runner, Bronco with rear locker, Rubi, non-LSD stock JL sport and my JLU with the true-tracs) to show us how differently each system behave in a sand pit.
• As expected, my Sahara with the truetracs was the only one that made it out of slippery situations without engaging anything extra (there was nothing to engage, either!).
• All made it through all obstacles, but the BLD in the non-LSD Jeep definitely wasn’t up to the task on the first trt and required picking a different line, for example.

TBH, I never really notice it that much, especially as the LSD seems to preempt BLD engagement. Regardless, I agree that LSD > BLD, so I will probably stick with my '21.

Nope. Not trying to convince anyone of anything, but instead trying to understand what people think of the stock LSD and if it's worth keeping. Seems like the consensus is yes, which is what I had expected.

I like the LSD as much as you do, but there is plenty of discussion in the forums regarding the (somewhat) failure-prone config that Stellantis chose to install in the JL. Might be worth reading if you haven't seen it yet.

...BLD try to move power around until something grip. One deliver right now the other fumble around until something work.

It's worse than that... BLD applies brake to the wheel that's spinning, making the engine apply more power to the other wheel. The problem with that is, if you're stuck in snow or mud, the BLD anchors the one wheel--that's the brake lock part--so now the other wheel has to propel the vehicle forward with one wheel braked. So then it in turn starts to spin. And then it gets brake locked while spinning the other wheel. They just bounce back and forth that way.

And if you're in 4WD, the other axle is doing the same thing, and you're just digging a deeper hole, two opposing corner wheels at a time. The only time BLD is useful is if you've exceeded your articulation capability and have a wheel in the air. Then it's useful. But no more so than LSD.

BLD is stupid AF. Change my mind.

...I like the LSD as much as you do, but there is plenty of discussion in the forums regarding the (somewhat) failure-prone config that Stellantis chose to install in the JL. ..

Fixing the LSD a time or two on your otherwise mechanically sound JL is still cheaper than buying a new JL that doesn't have it.
