This would be perfect for the sand too. Its just a poor mistake on Toyotas part not to have installed a traction control switch just so we don't look like fools driving around on a beach in 2wd and getting stuck!

Honestly, I don't think you'd break it by going 100 mph and engaging the locker. If you're on pavement and going basically straight-ish, the axle shafts are going at about the same rate. Having the mechanism slide over at speed doesn't seem like it would be much different than if both axle shafts were stopped... as long as they're maintaining a relative alignment.

However, if you were on wet pavement, and were revving up for a drag race burnout, and you cut loose and got ONE REAR WHEEL SPINNING... and THEN popped the switch... you'd probably eat the splines off of the mechanism.

I suppose this would also hold for a 100 mph tight turn. Any situation where the differential is actively in use to let the shafts be driven at different rates would be dangerous for the mechanism to engage into.

Of course, the FJC isn't in danger of accidently being involved in any 100 mph tight turns.

Will the FJC go 100 mph?

It'll do 100 in a turn in the dirt! Uhh... just a rumor, I don't know that. :worried:

I can achieve close to 200 mph myself, even without a vehicle, but I have to hold a head down position while skydiving to do it.

I'm guessing the terminal velocity of the FJC is probably a lot like that!

Cornering control, of course, is almost totally sacrificed in freefall.

how does this hack affect the MT 4x4's ?

In HI LOCK it should be like it is in LO LOCK. In 4 HI the transfer case is like an open differential between the front and rear driveshafts which means that any one wheel can spin and can cause loss of traction. Locking the rear diff. will mean that you will either spin both rear tires or one of the front ones. You will gain a small amount of traction but not near as much as our AT. The main benefit will be the turning off of the traction, vsc and abs controls. You should still be able to increase the fun factor with this mod. Perhaps someone has tried this on their MT FJ and can comment with authority.

I have discovered something new with this mod that may be helpful from time to time. With the 35 inch tires I'm running, I find that the traction control seems to be more sensitive and the ABS is less sensitive. I have found myself going sideways a few times with the ABS still turned on. If I wait until the truck is going faster than 40 mph and then turn on the rear diff lok, after 5-10 secs the VSC TRAC light will come on. You can now turn off the rear diff lok and release the differential and still have the traction, vsc or abs controls disabled. The only problem is that you have to restart the engine to clear the lights and re-enable the controls again.

I did this hack, and doing donuts in closed parking lots hasn't been any funner

I run 35's also. When I have been using my locker hack I also have been using my trac/vsc/abs cancel at the same time.

I'm still sorta confused. The reason AT's will see more traction than a MT is because you all are primarily in 2wd mode vs the MT which is always on 4WD?

Aside from all this, I wish I had a school or something around me that can teach me exactly what this rig can do. I'm new to all of this 4x4 stuff, lol. The transfer case stick is like a mystery stick to me. oh well... I'm a sports car guy (originally) but the FJ makes me smile in very different ways.

Sorry for the confusion, I don't know why I got on the traction issue. I tend to forget about the MT FJ's out there. They drive quite a bit differently than the AT ones. The main point of the hack is the defeating of the traction controls so that you can do what ever you want, when you want.

Kick ASS!!!

I did this hack per 31moppie instructions and the red locker light just blinks. Is it supposed to come on solid?

Blinking generally means it's armed to come on but hasn't yet. It seems to come on when it likes, I've found that's usually rolling at a very slow speed. The light should be solid though when it's locked.

 

[Layonnn]

it says in the manual, and it works in real life, when you turn on the rear locker and it doesn't engage right away try turning the wheel slightly left or right. while going very slowly.

I was going to do this Hack tomorrow, with a switch!

But I have a question:

You said this hack disables Trac, VSC and ABS.

I would like to have the ability to have the Rear Locker In 4 High and leave the TRAC working. As stock, the FJC, in 4 high does not have VSC but does have TRAC.

I shot some video in 4 high in deep sand and I could see both front tires digging and spinning.

I did a quick test and got side straddled, 2 diagonal wheels off the ground, in 4 low without A-Trac or Rear Locker and I would just spin the free two tires.

I put into 4 high and I could here the familiar brake chunking and the FJC pulled itself off the side straddle.

I would think that would be another great ability to be in 4 high and have Trac working up front and the Rear Locked! Is there a way to do this?

 

[Tim Scully]

Sweet!!! You guys keep testing this high speed diff engagement thingy. I need some more spare parts. A totalled FJ or two would come in handy around the house. After you blow the side of you carrier off while going 60+ mph and engaging the e-locker you'll be glad VSC and ABS are off.

 

[31moppie]

It is normal for the light to blink until the unit engages. Turning slightly from side to side as previously suggested should engage it and turn the light solid. You should see the three yellow lights immediately. VSC, ABS, and TRAC.

 

[Audiox]

My lights don't come on, just the blinking locker light. I think I'll put it back to stock. The last thing I want is my FJ sitting in Scully's backyard!

Thanks Timmah
My opinion exactly. I'm waitng for a snow-bound northerner to crown off the road into a tree and then complain.

It amazes me what people think this thing is for.
