TRD OFFROAD Prerunner and TRD OFFROAD.

You would have a button...

 

is there any way i can put a lokcer in my truck?
02 dc 2.7 automatic?

 

Any 6 lug tacoma can have a locker installed in the rear. any 4x4 can have a locker installed in the front and rear.

jdhodge- dont hate on the auto lsd. it works really good and it worked better for me than an 08 with the mechanical lsd and open front...did you try the yellow wire mod?

 

which would be the cheapest locker i can put in my truck. not lookin to go hardcore wheelin but a couple of trails

 

in the TRD OR wouldnt the truck be in an auto LSD until you locked it? or is it running completely peg legged until you lock it in. I always assume get the offroad cus then it has auto LSD and when that doesnt get the job done you can lock it. The sport only has the auto LSD? correct

 

... than to need it and not have it!!!

(This was a seperate post I made about a week ago, but may help the viewers of this thread...)

The more traction your truck has the better!

First off, quality tires for YOUR conditions are the first step to gaining traction.

Next, add weight in an empty truck bed to increase traction over the rear drive wheels.

Third, up the level of traction (if you have the equipment to do so).

LEVELS OF TRACTION:

1) 2WD, open differntial. If one rear tire has LESS traction, it will get the torque from the engine... result, spinning tire and then stuck.

2) 2WD, limited slip (differential clutch pack* or TRAC and AUTO LSD). If one rear tire looses traction, the clutches in a limited slip differential or the rear brake on the low traction tire works to transfer torque over to the traction tire. TRAC has engine output regulation, AUTO LSD does not. While the transfer of torque isn't equal between the two rear tires, it does improve the ability to get unstuck. (*'05-'08 Sport TRD)

3) 2WD, rear locking differential*. When activated, torque is divided equally between the two tires. Both rotate at the same rate. Should only be used to get unstuck or cross a difficult surface. Steering ability affected as there is no longer any differntial action (allowing one tire to rotate more than the other, as needed in turns). (*2WD Off Road TRD)

4) 4WD, open differentials. Front and rear drive. The tires with less traction get the torque if traction is less than equal to the opposite tire on each axle. If both tires on the right side of the truck get on ice while the two left tires are on firm ground... the truck stops moving as the two low traction tires spin. Having front drive added to rear drive generally enhances the trucks ability over any 2WD only system. The weight of the engine over drive wheels is one part of the advantage.

5) 4WD, limited slip rear differential. This is one step better as the torque will be shared between both back tires should one lose traction. The torque transfer is not equal but anything is better than one tire spinning per axle.

6) 4WD, locking rear differntial. Both back tires have equal torque along with at least one front tire getting torque. Big improvement in off road ability and a very popular feature used by may companies. All 4WD Off Road TRD Tacomas have this.

7) 4WD, limited slip front and rear differential (TRAC in H4). A big improvement in that torque is shared across both axles. All 2009+ 4WD Tacomas have this.

8) 4WD Active Traction Control (A-TRAC). The ultimate stock traction system equiped on 2009+ 4WD Off Road TRD Tacomas. Provides the traction of front and rear lockers while in low range (L4) by automatically matching a non-traction tire's rotation speed to the opposite traction tire, when there is a difference. Steering control is not affected making A-TRAC superior for trail driving. The rear locking differential is also on the same model trucks should one wish to use it or both together. The A-TRAC will only be active with the rear locked up to 3 mph. A-TRAC used alone has no speed restriction.

9) 4WD with aftermarket front locker (and faxctory stock or aftermarket rear locker). For the true hard-core off roaders as nothing to them can beat front and rear lockers. Both wheels on each axle are gear-locked together for smooth equal torque to each tire. Steering is very difficult, so use of lockers is limited.

The above is my understanding and experience with 4WD, and I tried to base it on the facts as I know them.

I hope it helps some with understanding how traction systems work, and how well Toyota has done at creating traction vehicles.

Toyota literature does fall short on explaining the traction workings, so I am inspired to write guides here on TW to our truck features, specially when off road!
