Hello all, I noticed recently that my PS was getting noisy especially while off roading as well as becoming hard to turn at full lock or when in a jam on the trail. Upon inspection I noticed that my steering box was leaking out of the cover and possibly near the output shaft. Long story but I...

I was having bad cold start issues and even though the GlowPlugs ohmed out as good I decided to take them out and replace with the Wellman plugs.... Needless to say I was shocked. Definitely don't trust your multimeter! Also I should state that I verified my smart start box is functioning as it...

Howdy Folks! Just wondering if anyone knows part numbers on the o-rings within the power steering reservoir vent cap. There should be a larger one for where the cal screws into the reservoir and then I think a smaller one for where the rotating vent mechanism is held into the cap via snap...

Really at a loss with this one. Tested all the electrical stuff and it looks perfect yet my Humvee is very difficult to start. Doesn't seem temperature dependent. So more than likely fuel issue. What tests do you recommend I perform next? What's common failure points in the fuel system...

Issue is as title says. I have the newer smart start box (nartron) paired with the yellow band temp sensor. Turn key, wait light on for 10-20 seconds, no amp draw shown on Guage, Humvee starts hard like it's got cold plugs... I also don't here clunking of relays anymore, but not sure if that's...

As the title says, my transmission light is on only when the key is in and engine not running. I just hooked it up finally so I don't really know if this is normal or not. Once I start the engine it immediately goes off. Tranny seems to run smooth but every once in a while it doesn't want to go...

Hey all, Just wanted to run this by you guys. When heavy off roading such as going over rocks or break torqueing to "lock" the diffs I get a good bit of power steering whine. Never really hear this when I am just driving around town though. Is this typical or should I be worried? Verified...

Hey guys, I was wiring up some lights last night and I disconnected the ground to the smart start box behind the Guages to wire my lights to it. Seems like its acting up sometimes now... Any chance I friend my $900 box by not unplugging the batteries first? I know you are supposed to...

Sorry if its been covered already. I just put in a new sending unit and Paradox by Design cooling lines. In the past the only thing I have ever done to purge air from the system is run the truck with no cap on the overflow tank.... not really sure if this does much. I have read on other...

Hi all, Took my M1123 on a 4 hour round trip plus some fairly hard trails this weekend. Needless to say I was impressed! ATV Riders on the trail were bewildered that a truck was there with them making it through the tough obstacles so well. However, the fan is running a lot on the highway/...

Hello, Took the humvee out for a drive around the neighborhood today and noticed temps over 240 (on the temp gauge anyway). I went ahead and popped the hood and noticed my fan appeared to be freewheeling so I did the usual of unplugging the TDM to see if it really was not spinning. I could...

Hi All, I just got done replacing the old box in my Humvee which is the model very prone to failure (forgot which one specifically) as well as the temp sensor/glowplug controller or whatever its called. Unlike before the Humvee now fires right up without fail every time. My only worry is the...

Currently in the process of installing a CDR valve in my 6.5.... I have no clue what I am doing and can’t find any resources on this. MY Humvee did not come with a valve, just an elbow connecting the two rubber hoses (see pic) can someone please let me know how to instal this thing? It would...

Hi All, I have a fairly unique issue on my 6.5 in my M1123. The truck came in a few weeks ago and was almsot immaculate. Truthfully believe it only has 500 miles on it. However, its probably been sitting for at least 5 years if that is the case, maybe much longer. One of the things that...

Thinking of going to some 39.5 Super Swamper Iroks... that being said I am going to start with a 2 inch body lift and if that is not enough I will go drop in some spring spacers and get another 2 inches or so. The only thing I am concerned about is the tire width. I want to run my original...
