    Flex your odometer

    Using some pretty big bolts for those mods.

    Anyone part'n out a Hummer H3?

    Those rear cup holders are weak! I have mine reinforced with a couple of self tapping screws where the pins broke off.

    Problem with 12 volt plugs.

    Wire straight to the battery and test. Also, when you talk about 12V plugs are you talking about the old cigarette lighter adapter thingys? I don't like to run much power through there. Too easy to trip a fuse. If the battery test works, consider keeping it up there but using a Blue Sea fuse...

    H3 Transmission dead?

    From what I've heard, that's normal or even inexpensive for that truck.

    Side mirror differences?

    The wiring is reversed in the newer mirrors vs. the older ones. Down is up, or left is right. One of the two is backwards. BTW, the Dorman ones do not appear to use glass; mine are scratched from cleaning the mirror. That never happened with OEM ones.

    Wow, I got a lesson in LS lifter failures!

    FYI, still don't have the truck back. Shop figured out the computer is now strongly encrypted (since 2019) and it require sending it to HP Tuners just to unlock ($500), plus $400 to turn off AFM, plus shipping. I warned him about this but he didn't take heed. Holley is supposed to be releasing...

    What’s the big deal?

    The difference in suspension is the shocks.

    2024 Black Sheep Week, Hurricane, UT - Mar 31-Apr 5

    Don, Reaper, nice to hear from you each. Hurricane is a bit of a hike for many, part of the reason we didn't see a few regulars last year.

    2008 H2 SUT - lifted 40" tires

    Good luck with the sale. Sorry, never saw the original post but I really didn't have a good guess on the value anyway.

    H3 I CANNOT Tow apparently

    He's not in NM! In July when I was heading west across 40 in NM, I was stuck in 3rd gear at 65 mph. Headwinds, altitude (much of it is 4000'-6000'), horrible aerodynamics, weight of off-road stuff, and tired engine made it a tough trip. And I was not towing.

    Just recently purchased a h3.

    Welcome to H4O! If you've got a 4" lift and you have a pitman arm, then it sounds like you have a solid front axle and a steering box - is that correct? OEM setup is rack and pinion with no pitman arm. If so, then you have a custom setup. Post up some pictures and maybe someone can point you in...

    Bought my first hummer (H3) and it’s unfortunately throwing a few codes. Looking for advice/tips you all might have.

    Welcome to H4O! For P0446, I'd start with a new gas cap and OEM is pretty much always better than aftermarket for some of these things. Also, if that part was replaced in 2022, I would check that too. Maybe a defective part, maybe not installed correctly. Sometimes when there are multiple...

    Coil pack

    Doubt it, and doubt you would gain anything unless you're changing a bunch of other parts like cam, adding a turbo and bigger fuel injectors. The best way to get performance out of the 3.7 is to swap it out for a 5.3 :)

    H3 I CANNOT Tow apparently

    Don't forget that the Alpha has 4.10 gears and that takes a lot of the performance feel away. Changing to 4.56 gears will wake it up significantly. I think that tow/haul mode thing is huge. When I first replied, I was thinking about the transmission and keeping the torque converter locked up...

    H3 I CANNOT Tow apparently

    Transmission could be tired. Long hills, especially in summer temps, are the bane of many towing vehicles. Ever drive up the Grapevine in SoCal? Many vehicles going that slow. But yeah, that's disappointing. I don't have an Alpha so I can't speak firsthand about it's towing capabilities.

    No drive

    As he said, fix the one obvious problem before you start trying to guess if there are other issues. If you don't like that advice, well go ahead and pull down the transfer case and tear it apart - it appears you're convinced that's a problem. I have a feeling that no matter what we say you're...

    If you only got 2 tablespoons of gear oil from the differential, it's a clear sign that it's bad. This is where you must start. If the gears are so broken that there's no connection from the propshaft to the CV axles, your vehicle can move in Park. It's not a sign of a bad shift fork. But...

    For the metal pieces in the front diff, can you describe them? Were they tiny slivers, like shavings, or 3 dimensional pieces that looked like they broke off something? Wait, there was 2 tablespoons of oil in the front diff??? There should be about a quart and a half! Makes me wonder if all of...

    POPPING NOISE

    I noticed that lower control arm bushings are not on that list. How do they look? And front diff bushings - that's all three, correct? What about the bump/jounce stops? Any witness marks on control arms or other pieces from impact? But I have a large popping noise in my front end when hitting...

    If it's has successfully switched to 4 Hi Lock, it's not a CV as the rear wheels would drive the vehicle forward. Plus you mentioned you can spin the front driveshaft by hand (and I'm assuming you're talking the prop shaft from the transfer case to the front diff) that means there's zero...
