What did you do with your H3 recently? NEW

[mjferencak]

Got these bad boys in the other day. Now I just need a weekend free to install them. I do plan on installing the other rear D ring. Not sure yet if I'm going to LineX then or not. Thanks THORparts.

I replaced four shocks. I went with Monroes on the rear and 5100s on the front. I also put in two new bump stops. I never realized how bad the ride was before I did all this. It rides like a new vehicle now.

Drove it, saw a fellow H3 and parked next to it for comparison shots...some haters would say panzer has been pumping some Roids...but I assure u she is 100% natty she just has great genetics. [emoji16][emoji16]

Cool pic! How high are your antennae? I don't think they would clear a lot of overpasses around here!

Put Seafoam in the crankcase, vacuum & fuel tank.
Fuel economy went from an average of 9 mpg - 12 mpg

Something was terribly wrong with my motor. Put on a spectacular smoke show

They are 10 feet long, mounted they are like 2 3 feet shorter than a semi so I'm good around here...except drive thrus but that's ok gives me an excuse not to be lazy and walk lol.

Finally got the new half shaft in and it drives!

Going around the block I had an occasional rubbing sound I could not place.

Nothing was visible under the truck, so when a half shaft goes, what else should I be looking for?

What kind of half shaft did you install and when does the rubbing occur, while turning, accelerating, etc.?

I ask cause I installed a new cardone half shaft and was feeling a vibrating/grinding through the pedals which was most noticeable during turns. I had a friend who is more car savvy but unfamiliar with my rig drive it and he did not notice any issues. I ended up putting the old oem half shaft back on after rebooting it and everything was back to normal.

If the rubbing wasn't there before I would look at any recent changes/installs as being suspect.

It’s a new ACDelco unit. I checked out the front end carefully tonight and gently drove around the block. There is a thunking noise that sometimes starts around fifteen miles per hour and is strong when decelerating.

My guess is that I fragged something in the differential as well. If so, how hard is this job for someone who has not done it before?

If you are replacing the front diff, pretty easy. If you are repairing it, it will take some learning if this is your first.

Got bored on a Sunday and made a 1-1/4" body lift. Tires are 325/80R16.

Welp, found some metal chips inside the differential:

here is my plan:

Pull it out and take it to someone local to rebuild, maybe even the local GM service centers. It looks like I need to
1) remove drive shaft
2) remove either driver or passenger side half shaft (does it matter?)
3) unbolt the sides
4) unbolt the center crossmember
5) drop and deliver to the shop

Am I missing anything, is that a reasonable approach?

Are there any special tools I need?

I thought about driving it somewhere but I’m sure that would be totally destructive, and I’m not really sure how hard it is to rebuild.

Any feedback is greatly appreciated!

Assuming you mean replace the entire diff vs repair of only the guts, then yeah that is what I guessed for a first timer doing this, and I’m not sure I really have the time for it right now.

That’s pretty much it. Don’t forget to unplug the vent hose and locker wiring (if equipped). Also, make sure you chock the rear wheels as the truck will lose PARK as soon as you jack up the front wheels.

If you don’t have any luck finding a reputable shop, feel free to send it my way. I rebuild AAM-7.6s quite often and I keep most parts in stock. Turn around is approx 5-7 days. PM if you want more info.

Fixed the exhaust leak that’s been plaguing me for almost two years.

Finally found time to get my Thorparts Gen II mounted up. Talk about a no drama installation. These are very well designed bumpers. I’m very happy with it.

It's the most wonderful time of the year!

Had to remove the fender flares to do some trimming and broke a few clips. Cheap to replace but still annoying

Replaced the lock & handle on my SnugTop. The original handle was corroded, and the cylinder lock broken. Got lucky and found a (new) replacement in a discontinued spare parts bin at a local SnugTop dealer.

While at it, I installed a Poplock tailgate lock (#PL1300H3T), and a Deezee Hydraulic Tailgate Assist (#DZ43102).

Went wheeling with Waysub yesterday!

 

[ludevick]

Installed a new CB radio, PA speaker, stereo head unit, infinity door speakers and plugged a leak in the roof. Next up is brakes!

The OnStar Microphone Adapter makes connecting the GM factory microphone to an aftermarket radio easy. Not just for the H3 Hummer, the OnStar Microphone Adapter works with plenty other GM vehicles too. This adapter probably works as the vehicle has a similar looking microphone. Otherwise, don't worry because the OnStar Adapter can be returned to me if it doesn't work. To connect the adapter to the microphone, just disconnect it from the wiring harness. Plug in the OnStar Microphone Adapter to the microphone and then run 3.5mm male-to-male headphone jack to the back of the radio.
