Can anyone tell me the distance from the plastic grill to the back of the vertical rib on the brush guard? I'm mocking mine up to fab brackets to attach it to my new winch mount and I think it's too far away from the grill currently. My original CUCV bumper is long gone so I can't fit check...

I've had Warn Premium hubs (part number 20990) in my 1009 for a few years, and they seem to be basically junk. I still have the front 10 bolt which is not known for being a particularly strong axle in a full size diesel truck, and these hubs are by far the weakest part of it. I've had 3...

I was driving my 1009 the other day and the brake pedal got pretty squishy. Upon returning home I noticed the reservoir for the rear brake circuit with completely empty of fluid. I haven't found an obvious leak which is surprising, but there has to be a leak somewhere and I'm sure I will find it...

My 1009 is a heavy pig. I knew that. I haul a lot of stuff around in it on the regular. 33x12.50r15 tires and a full size spare, huge steel plate bumpers front and rear, winch up front, full 27 gallon fuel tank, full 10 gallon water tank, a big steel truss welded on the rear axle, 24v fridge...

I am having overheating problems with my 1009, and would appreciate any help. It has a new badger diesel rebuilt IP, new injectors, and starts right up even in sub-freezing weather. The engine runs great, sounds great, and makes good power. But if its hot outside (>90F) or if I try to pull...

Hopefully this is a quick question for the CUCV electrical experts. I have a 240 mA current draw on the 12V battery connection with the key off. With the 30A headlight fuse removed that is reduced to 35 mA, which is about what I would expect for a CUCV. I have reviewed the TMs and both of...

The starter cable on my 1009 was routed from the 24v bus bar under the frame and to the starter when I got it. This seems unusual and I'd like to return it to the factory routing, but haven't found a diagram in the TM showing what that would be. Can anyone share a description or photo of how...

I'm replacing the injection pump on my m1009 and after cleaning off all the grease I noticed the timing mark was significantly advanced, about 0.100" Why would the previous owner have advanced the pump like this? To compensate for a worn timing chain? The truck ran fine but the IP was leaking...

I got a bunch of 6.5 parts several years ago, and am finally getting around to installing them on my 1009. I have some questions about assessing engine condition and I am sure I will have more questions as I work through the swap, and will document everything here in the hopes it helps someone...

My 1009 has been a daily driver for 5+ years, and the engine runs fine. Never had any shavings in the oil at oil changes, no knocking while running, or any other evidence of extreme wear. The "Low Oil Pressure" warning light comes on with the key, and goes out immediately after starting the...

I am getting ready to do a 6.5 turbo swap into my M1009 and am starting to collect parts, and have several questions. I've seen Diesel Care in Memphis recommended by Cucvsrus and others on here, and their IP rebuilds seem to run between $450 and $750 depending on what you buy. They don't...

I have a 6.2L in my 1009 that is running, but has low oil pressure (25psi cold idle/45psi cold at 2500 rpm, 5-ish psi hot idle 30 psi hot at 2000 RPM), what seems to be a slow oil leak from the rear main, low power, and just seems generally tired. I've been running the truck like this for going...

I have used NAPA Gold 6096 for my 1009 for years, but recently finished off my last case of them. I'm shopping for some new ones, and there are several options I was hoping to get opinions on. Napa 6096 - probably the best, $21/ea + shipping https://www.fleetfilter.com/filter/46096.html Delco...

My m1009 has a set of Goodyear MT/Rs in 33x12.50 R15 that are about worn out, and I'm looking to replace them in the next few months. That tire is no longer manufactured in that size unfortunately, so I need something else. I drive on the highway a lot getting out to the trails (150-250 miles...

I drive an 1986 m1009, manual swapped, air lockers in both axles. 33x12.50r15 Wrangler MTRs. In 10 years of winter off roading and highway driving in Utah I've never seen a need for chains. Roads are always fine for a careful driver with 4x4, and if the snow is deep and loose enough off road...

Has anybody ever seen a lift pump leak externally? I replaced it in 2018 and the truck starts and runs fine, and I don't have oil getting into the crankcase. There is a small amount of diesel dripping down off the bottom of the engine, and I know the injector pump is leaking (saving up for a...

I'm having a terrible time trying to get the front brakes working on my m1009. Both front calipers won't fully release and are constantly dragging. I just replaced the calipers thinking they may have had corrosion I the bores or something. Also replaced the pads and had the rotors turned and...

This is the 4th 70s/80s GM master cylinder replacement I have done (all on different vehicles, and all work well), and I have never bench bled a MC. Just put it on, connect the brake lines, vacuum bleed at each wheel using a venturi vacuum bleeder, and then take a break for half an hour or so...

I've been looking at F-13 and F-14 in the -20 TM for about 2 hours, but I dont understand what the diagram is saying. All passenger side marker and turn signals on the truck work. The driver side parking light and rear turn signal works, and the side marker light flashes when the turn signal is...

Well, I am not sure what to try from here. I just replaced my thermostat for the second time with another Delco 132-55 (GM 14077122), and the truck still will not warm up above 160F. I have a Vintage Air system with a block off valve in the heater circuit, so there is no flow through the...
