If you have and old school 4wd, put it in 4Lo put the brakes to the floor then the gas to the floor. I guarantee something will break. A axle, a diff, a u-joint? You’re talking about hundreds of HP through probably 30:1 gear reduction.
That’s why you don’t use a locked 4wd on a surface with good traction. In this case the brakes seem to provide that resistance?
I have seen lots of things break off road. The root cause is most often the long skinny peddle.
My Nissans have a similar anti slip system and when the ABS engages the ECU limits the engine throttle. I wonder if Toyota was trying to juice off road performance and not limiting the engine enough?
People think mechanical lockers are for traction but their biggest benefit is when you articulate the wheel off the ground it doesn’t spin fast , usually causing a broken axle when it hits the ground again.
