Oh so our diff is of the planetary type?? I thought it was the VC type. Just trying to learn about the car, not like they made a drivetrain brochure.

My dad has a tundra 2012 it uses an electrical switch to change drive modes

 

We have Planetary with a clutch, which is pretty good and very durable. You are the first failure on the forum.
Even with a switch, the tundra locks the diffs to create true 4x4.

 

No car can be driven on the roads safely with a fully locked diff, if that were the case when you turn 1 tire will spin faster and or hop when simply trying to park it. WRX has electronic solenoid powered diff lock.

 

I said an option to lock on slick surfaces. Just like every 4x4 truck. So if we add a wire mod, we create essentially what the wrx has.

 

The locking is in the differential not the transmission. Trucks have solid rear axles, and space to have a locker you need to have the system installed. Nobody as far as I know makes a locker for Lexus GS. The stock differentials have either open style diff or limited slip. Running a wire will not do anything for you. The wrx does have a rear electronic locker

Maybe there is a company that sells lockers, either electrical or powered by air.

If your looking to have your car "locked" for racing, there are ways you can do it. You can have a fabrication shop build you what is called a diff spool, a clamp style that locks the ring and pinion. Or the super easy way, and thats welding your diff locked, this way there is no going back to stock as the spider gears are all welded to each other.

 

Can anyone else confirm this? Is there model/part numbers to compare?

 

Yeah, I know about spools. I'm talking more about the 4x4 mode on many trucks and SUVS. The center diff locks, not the rear axle.

 

just put a gs body on a tundra frame and be done with it

We are having a huge snow storm today. There was a pile up of cars going up a hill. I didn't wanna stand there forever so I passed them all offroad) thankfully I didn't get stuck cuz I woulda felt stupid. there wasn't that much snow maybe 6-12 inches... Probably illegal but I woulda argued that standing on a hill full of cars struggling to get up isn't good cuz they might slide.

Then I was stuck behind some snow plows and they plowed a pile up to the hood on the side of the road. Drove through one of those(slowly) to pull into a Mcdonalds. That was fun.

Love getting sideways in a 2 lane turn overtaking some chevy malibu spinning tires.(carefully and safely) Lets them know who's boss.

and then I went and powerslided around a snow bank. I heard awd has lsd in the rear. I hope it's true but it does feel like an LSD because it can powerslide slide non stop.

 

This car must be a beast with good tires. No LSD but it has a very advanced traction control VSC system. Traction control works a bit like an LSD. And LSD though has the capability to act as a locker under very low torque (like 20ft/lbs), so both wheels spin together. If you have a powerful car on pavement or even hard soil, you get two tire skid marks.

On a very slick road, it is possible to go sideways when turning. Any more locking it become very dangerous.

After that the clutches in the LSD act in the same way the brakes in the Traction control system do.

But TC (like we have) could never have both wheels locked under any circumstance.Some cars actually have both.


It does pass a test where two side wheels are on glare ice and the others have traction, even with poor tires. It barely moves for a second, then you feel a clunk (center diff locking) and it moves away. When the center diff locks the two side wheels with traction can move the car. Now, if three wheels are on ice then the traction control system attempts. I found some areas to test it out, it seems to work, but it is difficult to test. Where I think it may have trouble is on an incline, with one wheel giving power. New Subaru can pass this test - three rollers, one traction wheel on a hill. Very few 4x4 system can pass it, would be fun to try. I may throw salt under one wheel of my sloped driveway to test if it snows here.

 

I swear I saw a post by you saying only AWD had LSD in the back.. But anyway I am 100% sure you can fit Torsen from 2nd gen GS into our diff. I've seen it done by people. Its usually the guys who work in the part recycling industry who can borrow any part to see how it fits up, lucky bastards

It's extremely easy, not just possible. . Car has plenty of steering angle to correct, just needs space to swing its ***.

Which traction control? VSC or the "drunk car". My VSC isn't working and won't be for a while. I don't even think car needs it. Does get sketchy on ice... I know with VSC it would do it's thing to prevent you from spinning even on ice. But whatever just use common sense.

Why not? If you fit up an lsd it shouldn't matter, no? Does it matter how power got to the diff? Through TC or a clutch? Maybe I missed the point.


so 1 side having traction is worse than both sides having no traction?
