OK, so it has a rear locker (or 8)...what about the front?

This article covers different levels of the ESP. BLD is one aspect that is always on.

I believe (in the above link) their referring to the Brake Assist System (BAS) as another acronym for BLD, or maybe it's more encompassing. They show its impossible to disable the electronic LSD in a table below the pictures.

This link below echos the other article giving examples of how ESP partial modes work. http://blog.chryslerllc.com/blog.do?p=entry&id=270 Because they love making acronyms the call BLD also ELSD. Then back to BLD.

They are all "cousins"..but yes....BLD is different.

I think it is like this:

ESP keeps you from losing control (steering wise) by applying the brakes to certain wheels before you spin out on the highway after hitting a patch of ice.

Traction control keeps you from spinning your wheels by applying the brakes and reducing the throttle.

Anti-lock brakes are anti-lock brakes.

BLD locks one wheel (in the air) so more torque can be applied to the other.

It is all software that eats up brake pads....

rightsideup I have an '07 with the 4.11 lockers but that was the first year and you had the option of ordering that way. Now I believe you can only get the Rubi that way.

I can tell you from experience that the BLD does work in 4 lo.

I've had one wheel 2 feet off the ground coming over an obstacle. Let off the gas and just try to crawl and the computer uses the BLD to work the ABS and traction control to vector some power to the wheel with traction. It's not a locker or an LSD, but it can be useful.

I have a Sahara and that couplers with my new 4.10s and OX selectable in the rear should get me through most places I want to wheel.

Rooster76 BLD=break lock differential. It's an electronic LSD(limited slip differential) controlled by the computer vs physics. Even in 4-lo. It's on ALL JKs even with the Trac-Lok mechanical LSD option installed. If one wheel on an axle is spinning it will apply some break to it, that transfers torque (power) to the wheel with more grip. You need to understand open differentials for it to really make sense. Watch this and you will understand. http://www.youtube.com/watch?v=K4JhruinbWc

TRAC-LOK (LSD) is an option for all JKs but rubicons. With the anti-spin rear/ Trac-Loc/LSD factory installed it would transfer more power over than just BLD and most likely quicker. It's main downfall is that it uses clutch plates that after 100,000 or less can wear to the point of being useless. They can be replaced. Eaton TrueTracs are a better aftermarket LSD choice. Both can work better in a slip situation with just a bit of break added.

LOCKERS are only good for offroad, and if your stuck. Unlike LSD you need to be aware when to use them to minimize axle/wheel damage. They will slide you down an off camber slick hill. Currently all rubicons have one on each axle (track-lok LSD is not an option). Also Moab editions can get a rear locker as an option(or LSD). They are much better in very large differences of traction. This is especially true if a wheel is in the air where LSD is useless if you don't apply some break.

The TracLok works great in mud and sand and I prefer it over a full locker here on the Gulf Coast of Texas. I run one in the front pumpkin also and there is nothing cheap about it's performance in this environment. I go wherever I point the front of my Jeep.
BLD means brake lock differential

All JK's have BLD.
Brake Lock Differential - it is software that kinda, sorta, almost simulates a mix of a limited-slip and a locker.

jcrawler93 sometime they come with limited slip on the rear

They didn't seam to be the brightest folks. Especially the ones that were standing under it trying to flip it back over.

panthermark Don't...understand...this...thread...

Oh...and one version of the Sahara does have an optional locker....the Moab.

JEEPDON MY Sahara DOES have selectable lockers; Dana 44's front and back; and a 4:1 transfer case!!!!! HAHA At least I can wheel in comfort!!

Yeah but, how do we know that's not a Sahara with lockers? That's the question!

Are those lockers "Anvil", or is it just the showroom lighting?
