To get an open diff to act like a posi is not that complicated. I used to do it in street racing also. In an open axle the power simply takes the path of least resistance. To get both sides to power you equal the pressures either by no pressure or a ton of pressure on both sides.
I learned that If you stand hard on the brake you overide the unequal pressure of the ground. Then you throttle through the brake in short bursts. This momentarily locks both wheels enabling you to climb even if one wheel is in the air.

Like I said I was getting quite good at it. What I did not take into consideration is the stress I was putting on the spider gears. They were not meant to work this way.
Now reading the specs of the true track the power takes the path of most resistance. In otherwords if one tire is in the air, the wheel on the ground gets the power. Definitely a better LSD alternative. So in the picture of the Jeep the wheels spinning are the ones with the most traction. As I said, watching how this thing worked was quite impressive. He just came through the exact same area as the green Jeep. Both got hung up, its a very tough section. Most rigs don't make it locked or not.
a limited slip is better than nothing, but in no way replaces the effectiveness of a real locker.

while the brake trick may simulate a light LS, it in no way "locks" both wheels.
you're putting stress on the brakes, not the spider gears
where did you read this? that is not how a trutrac works.

The brakes do not stress at all. The stress is in the carrier. And is exactly how I broke the
Spiders.
I read the specs from Eaton on the truetrac. I was mistaken the truetrack is a true LSD. What I read before was obviously wrong.
Probably will go with a lunchbox?

A. No one on here has ever even tried to make an open axle work.
Or
B. You have been locked so long you forgot.
Either way I would rather have a locker and you guys about have me talked into a front lunchbox locker. But if its going to rachet/kick/Buck on the street I will pass.
I want to be able to drive it every day not worrying about tire wear. and go on a 20hr road trip if I want. If it will do that then I am in.

Front lunchbox lockers you will only notice when turning into tight parking lots. Tire wear isnt even noticable. Rear lunchbox lockers, again, only noticable when tightly turning. However i have been in a couple rigs where i can only assume the locker was worn a bit, and it had a tendency to bang on rare occasion and unload when going in a straight line.
If they were truly dangerous, then so many people wouldn't be running them and be happy with them.

I dont have a front locker right now in my J10. it sucks. If you get a tire hanging, then that axle is useless. Its not a debate, its a fact. Not to mention the instances where you even have all 4 tires planted and still need more traction than the 2 tires with power provide.

More like you have 50 different people saying one thing and you going against it.
And now look at you, with a broken axle due to your "secret" way to magically lock an open axle.

Only 50? I need more of a spread than that!
And yes my secret "only to cherokee forum members" came back and bit me. The stock spider gears will not handle the abuse. From what people say on here not too many people break stock spider gears?
Alright already, I will be a locker and lollypop guy, I officially
