hubs stuck on after batteries disconnected

[Stranger]

my truck is a 99 f350 4x4 dually manual trans build date 05/99
my SOTF has not worked in a year and i usually just manually lock the hubs for 4wd
everytime I disconnect the batteries , when i reconnect it engages the hubs
in the past i have locked 1 hub, drove in reverse 50 feet , unlocked it and when i droove ahead it would disengage.
this time it is stuck
I have tried locking either hub and reversing , straight or turning side to side
and back forward after turning the hub back to auto , straight or side to side and no luck.
is this common ? how can i cure this ?
should i just go to full manual hubs ? what brand is offered for a dually that are good ?
any help is much appreciated !

I would just go with Warn manual lock outs. the auto hubs are nice just cause you ALWAYS have 4wd at the twist of a knob. But the Warn lock outs are the way to go once the stocks ones $hit the bed...

If you go with Warn make sure they are for a dually. The standard Warn hubs will not work on a dually.
