LSD vs Auto LSD

Auto LSD is crap!!! We installed a TRD mechanical LSD along with rear disc brakes in our truck. Auto LSD uses rear drum brakes which do not hold in mud and slush and only last 2 to 3 months before the liners are totally gone....making Auto LSD totally useless.

 

I would be concerned about the manual LSD interfering with the operation of VSC, if the truck is trying to brake one or the other rear wheel to avoid a skid.

 

Two year old thread is two years old...

 

Wondering why you have not been happy with the electronic brake system or the drum brakes?

I have had rear drum brakes on 3 Tacomas totaling about 300,000 miles and have never had them fail or need to be replaced. The big semi trucks use drum brakes... they have a much larger braking surface area than disc pads do. Disc brakes are just easier to replace and service.

Far too many here have stated their AUTO LSD works great for getting up boat ramps or other slippery surfaces in 2WD... So, maybe there is something not working on just YOUR AUTO LSD??? Could it be???

Sorry your Tacoma wasn't working as good!

 

In 4 hi with low traction available, the power is cut in the engine. Going up deep sand hills with the pedal floored, first gear, searching for traction, then... buurr, revs come down power decreases forward momentum stops. No tire spin no nothing. Back up turn off all nannies, zing right up the hill we go. Tell me how that system works great.

 

Do you have pictures of the process and maybe even a price sheet of how much it cost to do the switch from drum to disk?

 

I got the kit from here.

I think you need an education..We use these trucks OFF ROAD!!!! A trip in the interior could be as much as 600 miles. The road is full of pot holes filled with water requiring hundreds of brake applications. The sandy slush grit mud gets between the liner and drum and is crushed..grinding away the liner and drum. At replacement the drum is so badly worn it has to be trashed. It's a job in itself to separate the drum from the liners as a lip develops due to wear and the liners get stuck behind them. You have to go through the tedious process of trying to back off the liner tension so it clears the lip to be removed. Disc brakes wipe instead of crushing and grinding like drum brakes do so they last much longer and are far more reliable!!!
The Auto LSD becomes useless when drum brakes become wet and worn.
I have changed rear brakes in as little as 2 trips on the jungle.
Cheers.

 

No issues here..works almost like a rear locker with Auto LSD engaged.

 

Imagine Auto LSD in this mess...that is abrasive muddy clay ..it eats drum brakes for lunch and dinner!!!

 

It is in the 2012s.

H4 TRAC on = Engine retarder and limited slip light
H4 TRAC off (press button) = Full engine power with strong limited slip.
H4 TRAC off (hold button) = Full engine power with open diffs and no VSC.

Basically, TRAC functions the same in H2 and H4 now.

Myself, after 5 years of driving with the mechanical LSD that was in the early Sports I can say it performs awesome both on and off road... except in the winter. The rear end tends to wash out on slippery surfaces, which is always interesting at highway speeds.


(edit: nevermind... When I first checked Milowilli's profile I was pretty sure it said he was in a 2012, but now it says he's in a 2005.... Which is even more confusing since a 2005 doesn't have any traction controls)

 

You not gonna win with David K he is stuborn as mule and he thinks we all live in California like conditions

 

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. *

 

I shouldn't realy bash Auto LSD but for hardcore Toyota users like me it's not the way to go sorry!!

 

I hate mud

 

Haaa where we drive it's a way of life if you want to get to your destination!!

 

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;
