WOW! Are Isuzu parts that expensive? Your shops labor fees are very
suspect unless there is something unusual about the Isuzu that would add
that much labor. I had the 1/2 shafts replaced with new ones on my 1993
Nissan for $300 total, parts and labor.
If the CV joints are not damaged or making noises (like clicking in
sharp turns) then just clean, repack and replace the boots. ALL the
boots, not just the one(s) that are damaged.
First... CV joints are very robust and generally don't wear out unless
abused... like operating for fairly long time with damaged boot
allowing grease to sling out at highway speeds and dirt/sand to get
in. Or, when using huge tires, lifted suspension and high horsepower.
Your didn't say if your vehicle has any such mods... but I doubt you'd
have need to ask this question if it had! Also, it is fairly easy to
tell when they are worn out... either by clicking noises or
examination when disassembled for cleaning.
Second... you didn't say what model/year Trooper you had... vehicles
w/out full-time 4WD turn the front axles and pass torque a small
fraction of the time, only when operating in 4WD, and usually at low
speeds. So the front joints are basically good-as-new.

Not sure about the Trooper but thats not how the Amigo and Rodeo's are.
They are part time 4WD but with permanently locked hubs. With the
transfer case disengaged, the tires still cause the axles and CV joints
to turn. A bad design that many have remedied by replacing the hubs
with manual hubs to allow unlocking.
Turning the front differential too? all that extra mechanical drag
must be a drain on gas mileage.
But even this way at least it's not being asked to pass torque with
the transfer case disengaged although the grease will be flung out at
My '94 Rodeo isn't set up like that, it has auto-locking hubs. While
many swap those for manual lockers out of reliability concerns, I've
had good luck so far at 120K miles.
Isuzu stated they went with the permanently locked hubs in the late 90's
because of those reliability issues with the auto locking hubs. The
general public wants pushbutton 4wd (I don't!). My '93 nissan 4x4 truck
was sold with 140K without trouble on the auto locking hubs. I had an
89 trooper where the auto locking hubs disintegrated.
