You don't know the difference between locking hubs and a locking diff???
I do now after thinking about it.
I confused the difference with what my 4X4 GMC has - an open front differential, but engaged remotely not via hubs, but via a more reliable mechanical system that I installed to replace the electrically activated solenoid system. The solenoid system could have been prone to failure in the middle of a water crossing when one might need 4X4 the most.
Do you have a reference for stating that Ford 4WD HD truck front drive systems aren't offered with a locking differential option?
