93 Rodeo manual trans 4x4 proper shifting question

Greetings:

I recently bought a used `93 Isuzu Rodeo 5-speed manual 4x4 with no
operator's manual in it. I am not sure about the right way to shift into
4x4 from 2x4 . I also have a `03 Jeep Liberty auto trans and that shifts
into 4x4 while movingon the fly as long as kept under 50mph.

How does this work with a manual transmission? Should the vehicle be
standing still? Do you need to clutch? Any advise would be greatly
appreciated.

Thanx.

if the auto hubs aren't engaged, you have to stop and clutch. if
they are already engaged ( i.e. had had in in 4wd already, but didn't
back up after) you can slip it in and out as needed. if the rear
wheels aren't spinning you shouldn't need the clutch to slip it back
into 4wd (again only if the hubs are still engaged).

thanks bret. but i did't know about the engage, disengage, reverse thing.
not sure i understand you. could you detail that a bit more?

ok..

if you have automatic locking hubs (look at the center of the front
wheels, they say auto (or something to that effect) they are automatic
hubs, if there's a dial, they're manual hubs) all you have to do to
get from 2wd to 4wd is to stop ( clutch disengaged) and push the xfer
case lever forward into 4hi and then take off. the rotation of the
front axle will cause the hubs to engage, which engage the front
wheels. to disengage the hubs you need to stop, pull the xfer case
lever back to 2hi and back up at least the length of the vehicle.
this will cause the front hubs to disengage the front wheels from the
front axle.

if you don't back up after you pull the lever back, you will not
disengage the front wheels from the front axle; under this condition
you can push the xfer case lever back and forth (engaging or
disengaging 4wd) w/o stopping.

now if you have manual hubs, forget everything I said. to use 4wd,
turn the hub dials to lock. you can now engage or disengage 4wd w/o
stopping or clutching in most situations.

aha. i do have auto locking hubs and should have mentioned it, excuses
excuses.

sounds like rolling forward engages and rolling backwards disengages. so
the last item of confusion is: what happens if you go into 4x4 and shift
back to 2x4 without backing up to disengage the hubs. and then lets say,
for instance, that you park and then forget that the hubs are/were locked.
would that cause any problem or needless wear of parts? in other words, is
it best to always disengage the hubs if not using 4x4?

if the hubs are already locked, i can shift to/from 4x4 without clutching.
even if rolling? or must a manual trans always be standing still to get
in/out of 4x4?

thanks for your patience. you have been a big help.

correction.

what i'm asking in the second question about if i'm already engaged and
shifting back in and out of 4x4 on the roll, is it okay to that without
clutching?

so let's say i'm going 40 mph and come upon slippery road, hubs being
engaged, i simply push the lever up to 4x4? no need to disengage clutch
while doing so?

in most cases you won't have to push in the clutch to get it back into
4wd.

well it's a little more complicated than that, more like axle moving
faster than wheel engages it and axle not moving and wheel moving
backward disengages it.

well you'll back up at some point, usually out of a parking spot. the
only thing you have to worry about (leaving the hubs engaged) is
rolling back a little bit on a hill start and half disegaging the
hubs. this will make a godawful racket and you can stop it by quickly
throwing the lever into 4wd and back out. then you can get to a
parking lot and backup to disengage them..

yes, usually.
