Just posting some pics I took with my FLIR camera of the engine bay following a cold start (~10 degrees outside). Thought someone else might find it kinda neat. You can also see the way the rear differential is warmed up (in this case) which is cool. That's pretty much it. No other point to this...

Been hearing a squealing sound that lingers after braking intermittently. Pretty sure its the rear brakes because I can influence the sound by pulling on the parking brake lever. When I took a look, I noticed that one pad is wearing faster than the other which is probably not being helped by the...

I've been messing with the position of this switch such that it always reads continuity and also such that it always reads open regardless of pedal position. I have noticed no difference in the behavior of the truck whatsoever. Let off the throttle and RPMs drop down to idle while rolling...

Someone sent me a PM and said it would be helpful if I could provide the list of parts I had to purchase to restore the deep water fording system after GP gutted some pieces of it for whatever stupid reason they do that. So in case it is helpful to anyone, here is what I had to purchase to...

Looking for some words of wisdom from a HMMWV expert for an extremely intermittent electrical gremlin that has only occurred maybe 5 times in probably 30 drives now. Basically what happens is, while driving or stopped, the tach drops to zero, voltage drops to battery voltage (no alternator...

So I did do *some* research before I drained, flushed and filled my truck with Prestone Any Make Any Model green coolant. Apparently not enough research because now I'm reading that Prestone coolant is basically watered down Dex-cool that is dyed green instead of orange. I idiotically assumed...

I installed all the parts that GP removed and I think I got everything hooked up correctly. The question now is how do I know if it is working? When the valve is in "vent" or "deep ford" there is no air whatsoever coming from the vent line that is teed off to all the various components. I even...

I spent a long time trying to find a good place to hide a switch that disables the injector pump as a theft deterrent to casual car thieves that don't know their way around a HMMWV. I wanted somewhere that was hidden from line-of-sight and was also easily accessible. I think the high beam switch...

I need to convert my 2 man truck to a 4 man and it seems like Midwest has the kit I need to make that happen for a somewhat reasonable price. If I had to guess, the fact it says "replacement" in the product description leads me to believe this isn't an OEM supplied part like some of the other...

So, just learned a $20 lesson (two cans of r134a) and probably ripped a hole in the atmosphere but long story short, there were no schrader valves installed on the high and low service ports. I've already purchased a few types and they have all been wrong. Anyone know what I need to be looking...

I am servicing the hubs on my M1152 and the steering arm cover on the left rear wheel was leaking from a bad RTV job. When I took the cover off, I found the little seal that goes in the cover was all mangled. I removed it but it goes in the area shown in the photo I attached. What does this seal...

Hello everyone, I've spent a considerable amount of time scouring this forum for this specific version of a wait to start light issue and I've turned up nothing. I work at night so I get home around midnight (temps low 30s) and all week when I try to start my 2006 M1152, the wait to start light...

Hello Everyone, Just got my 2006 M1152 and am currently going through it and repairing/replacing all the little things that are worn out and broken on it. After sitting out in the sun for years, the side hood bumpers were incredibly dry rotted and basically crumbling to dust. I found...
