I may simply be having a brain fart (more than possible!)...but :-

With a fixed front locker, and manual hubs...

...is there any need for the TOD..at all?

When hubs are locked, I'll be in 4x4 mode..

When hubs are open, I'll be in 2x4, and dont need the TOD anyway.

Or..does the TOD need to be on, too allow full time 4x4 mode?

Cause if not...I can simply leave the TOD unplugged...(retire it!)
...and not have the front shaft rotating while in 2x4 'street" mode with hubs unlocked.

Please vote..

One..yes jo

Two...no jo ( and explain please!)

Three...yer nuts jo ( no explanation required .. but optional!!)

Thanks

jo
