Anti-Spin Differential Rear Axle - The rear differential can be locked with an electronic actuator so both rear wheels receive equal torque all the time for enhanced traction. Does this make sense? Does the LSD on these trucks have an electronic actuator to provide equal torque all the time...

I have a question for everyone. My truck is supposed to have the limited slip rear differential. With this differential should it even be possible for the rear axle to lock? What’s happening with my truck seems to be similar to what would happen if it had the locker differential and it were...

There has been no update as of about one week ago. As others have mentioned the manual states that 4WD auto can be used all the time. There was no noticeable difference between 2WD and 4WD auto on another truck we drove to compare to mine. My truck will not idle through a turn in 4WD auto.
