Lockers/limited slip and ESP

Hey all, new to the forum. I apologize ahead of time if my topic is discussed somewhere in the backwoods of this forum.

Two questions.

1. In the 2010-11 Rubi when the axles are not locked are they open, meaning do they give power to the wheel with the least traction.

2. Thinking seriously about a Sahara and putting a Detroit locker in the back and a limited slip from the same company in the front. Will it mess with the ESP in any way?

1. It acts as an open differential when no locked (cuz it is).

2. I considered automatic lockers. You'll want to do some serious research first. They have distinctive advantages and disadvantages. I went with a Detroit Truetrac in the rear. At some point I will be getting a selectable locker up front (prolly an e-locker).

I'm not a pro or anything. Just speaking from my personal experience.

A Detroit locker (auto-locker) WILL cause ESP/ABS issues, as it will cause what the sensors would consider odd handling characteristics if it locks while going around a turn in 2Hi. Even a fairly tight LSD can cause this (my ECTEDs [front/rear] do when off, and they're not THAT tight). Best bet is, as stoneaxe said, going selectable up front- that's where you're MUCH more likely to cause an issue, BUT, autolockers are very likely to cause a problem- Mark W.

I have the factory LSD in the rear of my X,, and I plan on getting the Detriot tru-trac mechanical limited slip for the front eventually. As far as ESP, I hate it and just shut it completely off..

BUT,, saying that, using the steering wheel dance to turn it off does not actually turn off all the electronic assist stuff, it basically just turns off the stability control, the BAS which helps off road traction by braking the spinning wheel still works, as does ABS.

You can only engage the Rubicon's lockers when in 4Lo. In 4Lo ESP is off.

Also, the Rubi spent hundreds, if not thousands, of hours in development to have them work seamlessly with the onboard electronics.
As for advantages and disadvantages, the biggest one is the Search button- it works! Mark W.

Perhaps we can give some info besides search based on your use or what you know rather than give the old search reply. After all the poster is new, he/she may not know what to search under.

If you havnt bought yet, and want to use off road. Go for the Rubi off the bat.

Or deal with head aches latter... all while paying out of pocket for it.

Actually if you are going to get VERY serious off road, you are better off with a sport or X and modding it yourself. That way you are not taking off the expensive Rubi stuff to put on aftermarket stuff.. But for 99% of any off roading a Rubi is great, and really for most people, like me, a Rubi would be nice but just isn't necessary, my stock X with factory LSD rear gets me anywhere I want to go.

But if you can afford it, Rubis are sweet.

I would imagine that Chrysler engineers but a shit-ton of time into working out the electronics and drive train on the Rubi.

Check out youtube. Do a search on limited slip differential. There are some demo videos that show the difference between limited slip and lockers in action.

Detroit (Eaton): Differentials

Sorry if that's not helpful.

I'm new, but I go way back with off-roading and This isn't my first Jeep ('11 Unlimited Rubi). We have had a couple of snows this season and I have yet to put my Wrangler in 4wd (except to get through the 36" drifts in my 1/4 mile driveway). The stability control is very good and I would never want a LSD instead of it. After all, I have 4wd for when it's needed. If my choice is LSD OR ESP, I'll choose the latter.

ESP is standard whether you have a LSD or not. I have the optional LSD and also have the standard ESP.

Sorry, for my newby-ness. I was told the LSD was no longer an option on the '11 Rubi's. Something I read somewhere said they scrapped it in favor of increased reliability under harsh conditions.

My point was based on this belief.

Anyway, I apologize.

So, would an after market LSD work with the ESP? Seems like it should.

Why would a Rubicon need an LSD when it has Lockers ?

Can you even have both LDS and Locked diff's ?

I could go Sport right now but rather save up a bit longer for the Rubi.

For me personally: "It's better to have it and not need it than to need it and not have it".

There are two schools of thought to this, and both work. One is to buy a rubi and don't have to deal with as many mods, the other is to buy a sport and with the money saved mod it out to suit your needs.

Take your choice. But even a Rubi will want a lift and regearing if you go bigger tires.
