New to me 2010 Wrangler 4door

Just purchased this Jeep it has many options but no LSD. Do not plan on serious off-roading just some Beach and Snow. Would it be worth searching for an OEM Trac-Lok center for the rear? Do they even sell just the Trac-Loc or must I get it used? Or just rely on the ESC?
thanks

I would expect most people to say get lockers.

But, unless you have wheels in the air often, LSD is just as good. Especially the Detroit True Trac. Tap the brakes and they will lock up for you offroad. Great manners on road too. Best thing to have for snow. Can 't say about beaches - no sand around here.

The OEM Trac Locks are clutch driven LSD. Detroit True Tracs are not, and are much much better.

Thanks for the reply Grog!
I think I'll go with the Trac-Lok OEM, I don't plan on ending up with a wheel off the ground situation where I drive.
Now the question is where to get that.
Can they be bought aftermarket or Dealer only? How about used? Would this be an easy addition for me? My Jeep has the Dana 44 with 3.73 gears.

Unless you're very sophisticated, you'll need a shop/dealer to do the install.

For the OEM limited slip, I'd expect you could order it from any dealer or maybe order it piecemeal from here if you know what you're looking for.

BUT . . . .

Help me out, why go out of your way to get the OEM limited slip aftermarket? It will almost surely cost much more and not be as good as the Detroit product mentioned by Grog, so what's the plan exactly? I'm confused.

The OEM limited slip is available ONLY for the rear axle, but here is a Detroit True Trac for the front and here is one for the rear. That would be miles ahead of the OEM set up and getting it installed by a good shop would probably--based on dealership installation costs and the mark up associated with Mopar products--cost less than getting the OEM limited slip installed in only the rear by a dealer.

For what it's worth, I want to install limited slips too eventually (or maybe lockers . . .), but I'd never even consider searching out OEM parts for something like this.

Finally, just an FYI, your Jeep's onboard computer does "simulate" a limited slip. When a wheel slips, the Jeep applies the brakes to that wheel, thereby preventing the otherwise open differential from transferring all the torque to the slipping wheel. That's on both the front and rear axles. Works pretty good, though I'd expect it couldn't hold a candle to the Detroits.

Oh, and WELCOME TO THE FORUM.

Thanks MTH. The Jeep still has the full remaining Warranty, I don't want to void it. There is also the Aussie version but I cannot find it for the rear.
I have read that the ESC uses a lot of Power which it does not have in excess.
From what I see the Detroit would run over 1 grand for the units plus installation. Just the rear would cost less depending upon finding one (used?).
Do you have any actual experience wit the ESC no LSD and power?? That knowledge would help my choice.

Living up in LI like you do, and with snow, would not get an Aussie. Lockers are deadly in snowy and icey conditions. LSD is much better.

I would bet that a similar set of Mopar LSD would cost more. Mopar- you can buy better but you can't pay more.

I have heard people getting Detroits for about $350 a diff but have never seen it that low. Just about any mod you do, even Mopar parts, will void the warranty, but only for the parts you replace. So adding in an LSD will void the warranty for the diff, not the rest of the power train.

I have the OEM lsd in my rear diff and it is pretty useless. Same with the computer traction control. When I regear will add in Detroits and pay the labor once.

Thanks Grog, I appreciate your thoughts. I am going to wait at least til I use it more in the slippery conditions.
I have had LSDs on all my Jeeps and other vehicles for years and they worked well. I will just have to see. Perhaps when you put your lockers in you'll sell me the your LSD.

Big picture, your warranty works like this: Aftermarket parts themselves aren't warrantied by Chrysler (though they may be by their manufacturer), and Chrysler won't warranty anything damaged by an aftermarket part. That's it.

Thus, an aftermarket LSD won't "void" the entire axle warranty or some such thing unless in causes damage. Given that a limited slip is unlikely to "damage" anything, warranty issues aren't really too much at play here. Up to you of course, but if I'm paying for the parts and work the OEM option just isn't going to offer me the bang-for-the-buck of the the Detroits.

The Aussies are lockers, not limited slips. Here's a recent thread on them. It does look like they only make fronts for the JK. I didn't know that. (See here.)

You may be right, but I'm not sure what you mean by "power." Are you saying it uses engine power somehow? I don't think so. It just applies the brakes when a slip occurs.

I have to believe a new OEM set up would be about a grand installed aftermarket as well. Maybe $800. Used stuff is always less expensive of course, but you've got to find it.

Just driving around this winter. We got some snow this year and everything was fine. I'm not sure how much of that is attributable to the ESC though. I never felt any loss of "power."

I just came across this in a recent post by J.B. on 2/4/11:
ESP Partial Off
This mode is entered by momentarily pressing the ESP
OFF switch. When in Partial Off mode, the TCS portion
of ESP has been disabled and the “ESP/TCS Indicator
Light” will be illuminated. All other stability features of
ESP function normally. This mode is intended to be used
if the vehicle is in deep snow, sand, or gravel conditions
and more wheel spin than ESP would normally allow is
required to gain traction. To turn ESP on again, momentarily
press the ESP OFF switch. This will restore the
normal “ESP On” mode of operation.

ESP Off (4H Range Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneuverability
due to trail conditions. This mode is entered by
pressing and holding the ESP OFF switch for five seconds
when the vehicle is stopped and the engine is running. In
this mode, all ESP and TCS stability features are turned
off except for the “limited slip” feature described in the
TCS section. After five seconds, a chime will sound, the
“ESP/TCS Indicator Light” will illuminate, and the “ESP
OFF message will appear in the odometer.To turn ESP
on again, momentarily press the ESP OFF switch.This
will restore the normal “ESP On”mode of operation.
This really explains use of the ESC to emulate the LSD.
I think I'll try this and see what happens.
Thanks for your help MTH and Yours Grog

Here's one more for you, this is from the 2010 Owners Manual:

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, brake pressure is applied to the slipping wheel(s) to provide enhanced acceleration and stability. A feature of the TCS system functions similar to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that is not spinning. This feature remains active even if TCS and ESP are in either the “Partial Off” or “Full Off” modes. Refer to “ESP (Electronic Stability Program)” in this section.

The Traction Control works by detecting that one tire is spinning faster than the other and applies the brakes to slow it down.

LSD works by detecting that one wheel is spinning faster and applies power to the other one.

The one experience I had with traction control was in a mud hole, and I was driving through it and my front tires stopped moving even though I was pressing the gas. they did start again, and luckily I got through, but computerized traction control is not your friend. Try it, and then ping me and tell me what you think.
