The manual lockers and manual xfer case always worked, every time.
it needs to be in perfect sync, otherwise you need to move the truck to sync it
or try again. this is not a flaw, it is a fact of the particular system
if they designed it to engage always no matter what, go ahead and add $2000 to
the price of the truck because you'd need a re-engineered tranny and xfer case
and in fact it does always engage, you just need to be a) moving and b) changing speed and not constant accel
