maybe its just i never really wheeled mine till i had the my full suspension on, combined with all the experience gained from wheeling my LJ with a burned up lsd through high school. I've never ran into the issue of lifting/unloading a wheel like that though. So when ATRAC actuates for me it has weight on both wheels. The times i do lift wheels i have my locker on so i dont notice only the front ATRAC working.

well everyone, I think I am done trying to figure out what Atrac is capable of.. I tried it this way, that way, every way possible. Going back to that hill in the video, it does do it better as long as I keep momentum.. momentum is key with Atrac. Unfortunately in some cases you do not want momentum because that momentum may just put in a wall or off the side of a hill.
Also, I found that in some cases when you are cross axled and only two diagonal wheels have any traction at all (example, Front Right and Rear Left or vise versa), you can get out of it by putting down some fairly heavy pressure on the brake pedal and giving it some gas at the same time. you want to release the brake pedal as little as needed to get the vehicle moving without letting the wheels with no traction run away and take all the power away.. This will get out of most cross axle situations as long as you are not going up a steep hill..
Also, if anyone wants to try that, if you let go of the brake pedal suddenly, while keeping the gas pedal down heavy, Atrac will be defeated instantly! Your wheels with no traction will just start spinning out of control.. atrac just gives up and has no idea what to do and how to stop it. you have to get of the gas and get back on the brakes hard and fast if you don't want your 4Runner to start ejection parts from all the shacking..
I did a lot of testing up different hills, and while Atrac is better than not having anything at all, my conclusion is that it plain sucks! and by sucks, I mean its too inconsistent, too violent, puts too much strain on the braking system, on the axles, and on the whole drive train..
Here is some pictures of my last run.. Take a look at the axle, thanks to Atrac. This is what happens when you run Atrac too hard trying to make it do things it doesn't really wan to do but I guess technically could..
If you plan to run your 4th gen 4Runner hard, I mean really hard, do not rely on Atrac or you may be walking home. Get a locker or something

Just curious if you were in 4LO when this damage was done?

welcome to the broken CV axle club. after i broke both front CVs at the same time and had to drive 30 miles home is when i decided i needed a locker. best investment i've made aside from the sliders. but for mild to some moderate wheeling ATRAC should be fine for the average user, i'm just not the average user.

Yep.. 4 Low, good momentum going up the last hill in the original video that the Land Rover ate right up.. No locker, Atrac only

Did you have a spare CV with you to do a field swap?
