I’m certain most of us are running civilian truck/SUV/car pressures. We should keep in mind that these are designed for military applications, they have beadlocks or runflats for a reason. A good example of a lesson learned is my trike vs the motorcycles we ride. The wife and I each ride 1400...

Just out of curiosity, what tire pressures are you running? When I got my M1123 last June, I originally ran 40 PSI in all four, and could have sworn fillings in my teeth fell out on the road, couldn't even imagine off roading. After some research and finally Mogman pointing out that the TM...

Have you Ohm checked and voltage checked your throttle position sensor? If that doesn’t read correctly, it may not understand to shift into 4th and TCC. That was part of my problem anyway… Best of luck, don’t throw the new TCM in until you have a definitive answer, IMHO.

South Dakota is happy to register a HMMWV without any issues.

. In my case I had codes 22, 37 and 85. The first two were fixed by adjusting the TPS. After cleaning the connector with contact cleaner the 85 also went away. Make sure you use some di electric grease around the plug after cleaning, ANY fluid could cause a number of issues. The...

. In my case I also bought from Melton Industries, they came in a zip lock baggie. They are 3/8" and ohmed pretty consistent. So far they have worked now for 7 months, pretty flawless, minus a 3 week period when it started hard and filled the garage with white smoke, pretty much anytime under 30...

Reviving this older thread to see if anyone has formed any sort of group in the northern Black Hills. Although my wife and I have lived here since 2001, I had my M1123 just about for 10 months, been trailriding around the Piedmont and Deadwood area. Wouldn't mind getting together with other...

It is always good to be aware, especially if you had an exhaust leak, you could be pumping carbon monoxide and dioxide into the cab. If you find yourself getting headaches or getting tired without obvious reasons, remember this and other openings. Usually not a problem since the cabs aren't that...

Or just put a 3/8" on it. It will not fit the china knock offs. But I've heard of reliable china-coms as well.... Just my guess the ones you put in are not US made, so not Wellmanns either.

One sure way to find out if the are China-com stuff is if they are 10mm vs 3/8". US made are always 3/8", never 10mm. Not saying all 3/8" are the real deal, but 10mm never are. What size wrench/socket did you use?

. Check all the major ground cables, AND the starter cable and ground. Make sure you wiggle any cables or tighten lugs ONLY with the ignition off. A sudden reconnection may fry components and most likely will create arcs and sparks... The trans light should stay on if the engine is not running...

. Further research showed that the models listed on the 2nd part are all the A2 models. IIRC the M1123 is considered a version of an A2. Can anyone confirm or am I on the wrong track?

Found my right rear tie rod to be worn out while doing semiannual inspection. Ordered the both tie rod ends and started to take them apart this morning. Should have learned from the front that this type of maintenance is better done in a shop rather than in my home garage... However, the tie rod...

None of us are getting younger, take care of yourself and keep us posted…

. Maybe it's plain CYA, but you just can't argue with the TMs. There may be some other parameters that are different in the military use compared to most civilian versions. RWH, Mogman and other old-timer engineering minds may know more.
