If I lock on side of the differential down, how fast will the free hub turn? Twice as fast as normal? or the same speed as the drive shaft? I have been told both.

I guess I can jack up one side of my pickup and spin the drive shaft and count the revolutions for shaft and wheel.

Kicking self for selling off my Taskforce trucks.
Still looking for an LCF or conventional big bolt in decent shape.
As of 10-26-2022, A 55.2 Taskforce long bed now the work begins
