How to make new cucv reliable?

[realm]

What are the parts most likely to go out on a used cucv with 100k miles?

Already done:
Oil change
New fuel filter
Auto trans fluid changed
Undercoated everything
New glow plug relay
New Alt belts

On my to-do list:
Radiator flush
Tcase fluid change
Diff fluid change

What else may likely fail and leave me stranded?
Glowplug card?
Fuel filter base?
Injection pump?

STARTER!!!
ALTS!!!

those things seem to fail when you need them..

I don't know about yours but mine likes to burn up fuses, wires and alternators every once in a while.

Sounds like you are off to a good start.

Hope you changed trans filter when you did the fluid. Other than that, these trucks were fleet maintained, some of the stuff that breaks on them may have already been fixed. I leave mine stock and take it as it goes, They can be very dependable if you use them as they were intended.

These are the things I do to a cucv that I get and don't know the history of:
Change all fluids and filters. Replace the starter relay under the dash. Replace the glow plug relay. Make sure ALL of your glow plugs work. Test your batteries. Put in a new mechanical lift pump and rod. Replace rubber hoses, especially on the vacuum pump. Steering stabilizer shock is probably still original and not doing a thing, get a new heavy duty one. Inspect or replace vehicle shocks. Inspect all front end components including the axle u-joints and hubs. Have the rear drive shaft balanced and replace u-joints on front and rear shafts. (Many come from GL bent or dented and if they're not, it will still ad life to the joints). Have YOUR starter and alternators rebuilt by a reputable place that specializes in starters and alternators. You will notice a big difference. If an M1009, remove the access panel on the tailgate and clean, lube, and adjust all parts of the window mechanism. Now you have a good baseline and confidence in your CUCV.

Im going to put a starter brace on mine and replace the old starter bolts with new GM ones.

Your cucv has 100K miles on it? How long has it been out and road licensed?

Among the many things already listed:

Pitman arm, sway bar bushings.

Hub service

Ensure you have good connections on your windshield wiper motor and maybe even get a spare.

Get the best brake pads available and shy away from cheapies, especially if you plan on hauling or towing a lot of weight.

Those little light adjustment clips were always breaking on me until I finally had each of them replaced.

Oil and transmission cooler lines were always leaking on me until I had them replaced.

Fuel indicator is prone to malfunction

The speedometer cable piece that goes into the bell housing is prone to breaking.

Radiator failure.

This is in addition to what has already been mentioned.

The easiest way it to time travel to 24yrs ago when these trucks were new .

haha i think i agree with johnfire. I think just keep it up on normal maitenence and it should be fine. I havent worked on too amny of the older diesels, but your from tennasee so you have less chance of it rotting out like i do

Well so far adding to my "done" list is:
-replaced underdash relay with HD one
-replaced starter with gear reduction one & bracket
-Fixed slight valve cover leak
-Fixed small radiator crack
-Replaced radiator hoses/clamps
