With auto hubs, what is the advantage/purpose of the "lock" setting over having it in the "auto" setting.
I knew someone would.pee em off and put manual ones on
hahaha i couldn't resist.
NO the wheel does not have to make a rotation only the drive shaft, diff and axle needs to rotate to lock them in.Umm, doesnt the wheel have to make 1 rotation before it locks in, after you have engaged 4wd, which wont happen if you are already stuck.
This is the time that you need to get out and lock the front hubs with the spanner.
