Locked or unlocked?

[ChiXterra]

When 4wd is disengaged, the auto lockers are supposed to be disengaged. With those disengaged, shouldn't you be able to spin the front driveshaft? Or is not a true lockout? My 4wd is disengaged, and I am not supplying power to the front tires, but with the front off the ground, the driveshaft will barely turn, before it locks.

The hubs can lock and unlock independant of the transfer case. If there is some parasitic drag on the hub it can lock on the shaft.

The hubs lock if there is power to the drive shaft.

So, if you're driving and you put it into 4WD, the front drive shaft will start spinning. When the tire starts to slow down, but you're maintaining speed, the hub will then lock in, keeping the tire going. Once the hub is locked in, it will stay in until there is no longer power to it to keep it locked in.

This is also a problem with automatic hubs in that they can lock and unlock under certain driving conditions.

But, if you're parked, in 2WD, and you turn the drive shaft, the hubs will engage, not allowing the drive shaft to spin.

This is where manual locking hubs come into play in that no matter what the drive shaft is doing, you can choose when/where you want the hubs to be locked in.

Exact answer I was looking for!
