    I guess u didnt read my post below..Auto LSD uses the drum brakes to stop the spinning wheel. In our Application Drum brakes sometimes last one trip in the Jungle before they are totally worn out and need replacing. The road is full of muddy sandy waterholes that eat up drum brakes for lunch!!! Drum brakes operate on the crush and grind principal ..crushing and grinding anything that gets between the liner and drum. Wet drom brakes are useless so no Auto LSD functionality. Disc brakes wipe so they are more reliable and last much longer. And by the way i Built and modified a 2010 Tacoma and drove it in all sorts of conditions and the Mechanical LSD is Far superior. I installed a Mechanical LSD from an 05 into the 2010 with Auto LSD and also converted it to Disc Brakes.
    Trucks i build are not weekend warriors..they run into the Jungle several times a week and have to stand up to the severe road conditions. I have been doing this for years so i know what i am talking about..
    here is the 2010 build.

    Following are typical pros & cons for both disc and drum brakes:

    Drums
    Pro - Less expensive since they're already stock on Broncos
    Pro - Drums work better then discs as emergency brakes
    Con - They stop poorly when wet and can get clogged with mud
    Con - Stopping power can fade with repeated hard braking
    Con - Larger tires

    Discs
    Pro - More consistant, straight line stopping power
    Pro - Dissipate heat better to stay cooler
    Pro - Less affected by water or mud
    Pro - Easier to maintain and faster to replace pads then shoes
    Con - More expensive to install (but maintenance costs should be less)

    Most people will agree that discs are better than drums. However, stock drum brakes can be effective if they're in good working order and properly adjusted. Typically when people upgrade to disc brakes they're replacing worn out drums, so they see a vast improvement and are quick to credit their new disc brakes. Just keep in mind that when someone raves about their new disc setup some of it is due to simply having new parts. *

    Mine is 2wd, so I know the system works a bit differently, but...why would you be in sand or mud with TRAC on, when you could have A-LSD?

    ... right.
    I don't think your truck is intended for that kind of use. You might be better off with one of these;

    We have a 2011 truck with both Auto and mechanical LSD installed as the Auto LSD eats rear brakes in less than a month.

    ok so I have a 13 sport 4x4. in 4hi is the engine retarder on with trac on and then is turned off when the vsc button is pushed or is it off automatically when i put it into 4 hi. I know the '12's have this design, but what about the 13's?

    I had a mechanical LSD on my Dakota. The Toyota brake system is much better than mechanical. With mechanical both wheels must have traction in order for it to work. With Auto LSD the wheel with traction will get you moving even if the other wheel is spinning.

    Stick with what you have.

    What??? You can't be serious. Toyota would never design a system that would do that.

    Mech. LSD is a proactive traction control system. It provides power to both rear wheels before you lose traction. Auto. LSD is a reactive traction control system. It only operates after you lose traction, until then you only have one wheel drive. If I had a choice I would take the MLSD any day.

    You are half correct. Your Dakota had Truetrac, which indeed does have a problem when one wheel completely loses traction. However, Toyota used Hino LSD which works more like lock right, except it does not fully lock axle. Apples and Oranges.

    Yes I am correct..the sandy mud Eats rear brakes in less than a month. I am talking about Guyana South America..extreme conditions. When the brakes are wet and worn out...no AuTO LSD!!!!
