    Suspension part out…

    Not much left. A nice set of wheels/tires.

    Full time 4x4??? HELP!

    Also…just like any 4x4 vehicle, don’t drive around on dry pavement in 4HI-Lock mode. Transfer cases hate this! The binding that occurs will put a tremendous load on the entire driveline. 4x4 vehicles (all of them) depend on sand, dirt, gravel, snow, ice, etc. to safely operate in a locked...

    Full time 4x4??? HELP!

    There is no 2WD. The H3 has (3) t-case modes. 4HI is the normal mode that includes variable output and torque splitting between front and rear axles. Basically…the front axle gets reduced power during cornering to prevent binding in the driveline. The split is preset at 60/40 but it can...

    2024 Suspension options available?

    Airbags! It’s the ONLY way to properly support extra payload. Beefier springs, shackles, or shocks…are all band-aides. This because the spring mounts, shackles, and bushings, as well as the upper shock mounts, are not designed to be overloaded. During an overload, the springs will flatten...

    BCM Questions

    I have the same exact issue. It’s not from water. My 08 has 54k miles and sits in the garage 99% of the time. The BCM is bone dry and has never been touched until I took it out last week. Because the H3 is such an electronic retard, it will often drain a battery if it sits for a month or so...

    Torsion bolt wont turn

    You don’t need lift keys. There should be plenty of thread left. Most likely your keys are not indexed properly…very common problem. This often happens when the suspension is disassembled to replace worn parts and doesn’t get put back together correctly. To fix this issue you must remove the...

    HUMMER H3 HELP ME

    Replace the passlock dohinky inside the steering column. You can get it on Amazon for around $90. Good for another ten years.

    Frame swap on a 08 h3 alpha

    Sbc350's comment "Your welder should be able to fabricate a perch for the body mount. Pretty straight forward." is a good assessment. However, you must have something to actually weld-to! My experience with patching H3 frames is that you just keep blowing holes thru rotten metal every time you...

    Rear sunroof drains on H3T

    I am going to recommend that the owner remove all the seats, console and carpet. Flip the carpet & pad upside down and lay it in the sun for a week. Drop the headliner and inspect the connections at the sunroof (add hose clamps if necessary). Clean the drain tubes out (with plastic weed-eater...

    Rear sunroof drains on H3T

    I recently did this procedure to a customer’s T, and determined that most likely the hoses are not connected at the sunroof. There is staining at all four corners of the headliner, and the interior smells like a wet dog. After some head scratching I have decided to leave this task up to the...

    Rear sunroof drains on H3T

    You can get to the drain hoses where they exit the rear cab wall. That’s about it…the rest is hidden behind pillar covers and headliner. Fold the seatbacks down. Remove the black plastic cab wall cover. It has a bunch of plastic clips in the middle and the top edge hooks onto some sheet...

    thud when accelerating

    A sticking caliper can create a thump, but only when using the brakes. You might take a drive and put the AT in 2nd or 3rd gear. Then roll on/off the throttle using engine compression to twist the driveline back & forth. This will tell you if the thump occurs without using the brakes.

    thud when accelerating

    Looks normal to me. These trucks have sloppy drivelines. At that mileage, you should probably replace the t-case chain…but I would not expect a huge improvement. As for the ring & pinion lash…you can’t really judge that from grabbing the driveshafts. This is because some of the looseness you...

    2/4 Band is Shot in my 2009 H3T

    150k on a 4L60e is about it. They just don’t seem to be very durable. I just had one rebuilt and upgraded in a 2006 H3…$3300. I’ve got another H3 with 152k and it seems to have some harsh shifting issues.

    Ultimate IFS upgrade package....

    I've had all this stuff listed on here for some time...getting no action. So I decided to put it on here as a "package deal". It doesn't get any better than this unless you break out the torch & welder. This is the unicorn front diff that everyone wants, along with some other goodies. Here's...

    Broken screw removal help.

    Drill out the old ones. Re-tap the plastic to a larger size bolt, (plastic taps like butta). If that doesn't work, or if you want to keep the factory screw size...grab some riv-nuts (McMaster-Carr) and install them in place of the originals screw holes.
