Possibly going to look at a 1986 M1009 CUCV tomorrow, the guy wants 1500 for it but he says the fourwheel drive is broke, rust in the normal spots, going to need new tires soon, speedometer is broke and says that it starts hard in the cold and needs a shot of starting spray to start when cold due to something about needing the updated glowplugs and relay, it also has about a 100,000 miles. I read on a website that the engines in the M1009 wear out around that many miles, is that correct or is the website wrong, seems hard to believe that a diesel would only last a 100,00miles
If i were to buy it I would need to repair the four wheel drive to be usefull truck for my purpose and probaby have to do something about it starting in cold weather being i live in WI My question is if its stilll a decent buy even with all the things wrong |

It won't make it past 100k if you keep using starting fluid on that engine. That's one of the worse things you can do to the 6.2l engine.
The stock glow plug system is prone to failure but it's not hard to figure out and there's a couple of ways of updating/bypassing the stock setup. Other common causes of hard starts with the CUCV family of vehicles is a bad filter base (bad o-rings or the plastic nipple for the water sensor getting broken) and the return line check valve on top of the fuel pump going bad. |

I have two of them, doesn't sound like that great of a deal..... I agree, there are many M1009s around that are lower mileage and in better shape than this one. The up front cost will be higher than $1500 but the one the OP is looking at sounds like it's been rode hard and put away wet too many times and could easily soak up a couple of thousand getting back into good running condition. |
| I have a friend who has one of those CUCV it has been a bigger money pit than his Deuce has been even though he did a wheel conversion on it. I'd really look hard into finding one that has no problems. You might pay more for this but its worth it in the long run. My buddy has spent the last 4 months tracing starting issues and lights, he got it fixed for about 1 week then it stopped working again. He only to discovered 3 weeks ago that all of the wiring inside has to be replaced, he is retired Vietnam Vet the guy only wanted something that was easy to maintain and fit his persona. |

It was perfectly modeled after genuine decals except that it was all in white chalk. I laughed so hard when I saw that.

The 6.2 is an underpowered pig of a motor with longevity issues, but if you get it young enough you might stand a chance at making a driver out of it. That's what it looked like when I read the stats, which led to my questions above. It's hard to find a diesel 4x4 with 40 to 60,000 miles for $2,000, unless you are talking about CUCVs. The 6.2 is no powerhouse and the truck lacks creature comforts, but if you carefully pick out a nice one they can be a heck of a deal. |

I bought mine because I wanted a solid beater, 4wd, and diesel. Ability to run filtered WMO/trans fluid/hyd oil/etc. is a plus. You'll get that with any older diesel though. I really wanted a M1008 but the 4.56 gears just wouldn't work for what I need, so I ended up with a M1009 for $2,500 with 49k miles on it. I put about $500 in maintenance and parts in it and would trust it to drive across country now. Even with the factory sized tires it does surprisingly well in mud. The common problems are easy fixes. I'm tempted to buy another at auction, do the fixes, and maybe turn a profit on it. |

Not as sexy or fun as a Deuce, but a bit more practical. |

If you plan to do any distance driving, and have the stock tires, swap out the 4.56 gears in your axles for 4.10s. These trucks were intended for a top speed of 55mph and are geared to reflect that. At anything above 55mph, the 6.2l will be screaming, and you will have terrible mileage.
Don't worry about it affecting towing ability. I was able to haul 13,625lbs across the country when I PCSed to Fort Benning. That's almost twice the GVWR, which is 8500lbs. Those 6.2s may not have a lot of ponys under the hood, but they have torque to spare. PS. I was getting 13mpg during that trip. That's the lowest I ever got. PSS. Make sure to install a battery disconnect that is accessible from inside the cab. If that infamous "starter relay" under the passenger side dash ever gets stuck in the on position, you'll be very glad you did so, 'cause the only other way you'll stop your starter and other electrical system components from going critical, is if you can unplug the battery's fast enough manually. Ask me how I know.

It will eventually fail even if replaced with a new one. |

My M1028 with a fresh driveway paint job. 
It has a built 700R4 in it, I can cruise at 75/80 all day long... 6.5 turbo sitting in the box to be mounted up soon. |

I never said it wasn't a mite on the high side of the tach, just that it would do it. Unlike a Deuce which just chugs along, the M1009 can go with the flow of traffic on the highway without getting run over. |

To whomever said they'd consider buying, improving, and flipping one... The .gov site has several of them in the midwest and west going for $400-700. I know several people that would gladly pay $3500 for one that was turnkey. Not necessarily cleaned up or anything, just reliable. That's what 100dollarman does and they move fast for him.
Hell, I'd be in on a group buy

Shit dude, you might as well buy one that runs, and works, for 500 from the auction.
The ONLY appealing thing about these trucks, is that they USUALLY have a decent body, and they can be had for a grand or less at auction. If this one is rusty, there is no point. The 6.2 is a piece of shit, so you might as well take that 1500 bucks, and go buy a CUCV at auction, or buy a decent civilian truck. |
| If you aren't mechanically inclined id look for a K5 blazer with a Chevy 350 in it. Much more common for the average joe and if you throw out all the CRAP and go with a simple ignition and carb set up short of machine shop work there isn't anything you cant do on it with a a small investment in tools. Yeah diesels are great but there have been so many SBCs build used motors , parts and accessories are really cheap. |

Finding them in running condition at the auctions is getting harder and harder. Most of them are listed as not running, no keys, parts missing, etc.
Unless you feel like driving there with a trailer and hauling it away, you're better off to pay one of these guys that buys them up and puts the time into them. |
