What did you do with your H3 recently? NEW

[EndeavoredH3]

Bebe has a Complete rotor to rotor sprung over rear end with an ARB for sale.
She may part it out
No compressor

I may be interested if she decides she wants to part it out!

Some concerns with PowerStop calipers. Supposed to be pressure tested but leaks with no brake pressure. Last set had early failures too, quality has dropped.

View attachment 33906

We were maintaining around 10 h3s at one point and were exclusively using powerstop z36 full kits with calipers as they came due for new brakes. Were were swapping over to powerstop and new stainless hardlines and soft lines with full fluid flush. About four years ago there was a national shortage of H3 powerstop calipers and they must have switched to a new manufacture as we started having issues with them leaking and eventually seizing. No good replacements unfortunately since then. Same issue with the "OEM" calipers from GM parts

I seem to recall that Steve (reloader) mentioned that our calipers are the same as some toyota model calipers, Fj cruiser or 4 runner of some years. I can't remember the specifics though. Could be work investigating that and finding out if they work and are a suitable replacement.

Always happens at the end of projects.

Stud installer decided enough was enough.

New BF Goodrich All-Terrain T/A KO3 315/75R16 and AmpResearch Power Step on my 2008 Hummer H3 Alpha

Front and back differential, gear oil changes...

Surprised the front old oil looks pretty grey after only 40k miles.

Latest mod is a slip-yoke-eliminator on my BW4494. For quite some time, I have noticed that the standard rear driveshaft was running at a pretty extreme angle. Not only is this bad for the u-joints but, it also causes the factory slip-yoke to eventually wear out the bushing in the t-case tailshaft. I could often hear a "rattle" on deceleration...never realizing it was the yoke chattering in the tail shaft housing.

This project was pretty simple once I found the correct parts to do it. I made a drill jig (from an old TH400 yoke). Then I drilled & tapped the output shaft and bolted-on a 1350cv yoke. Next I had a new 1350 driveshaft made. It uses a fixed cardan joint at the t-case, and a slip & stud at the rear diff. This is much like Jeeps and Toyotas have used for years. Now both driveshafts can be removed without loosing any fluid, and because the yoke is not slipping in & out of the t-case...I'm hoping the bushing and seal will last much longer. It is so smooth at 80mph....much better than the standard rear shaft.

Reloader had done a similar mod. Are you planning on making a kit to sell? Will be interested after my swap.

Interesting... Any pics of the solar set up?

I plan to run the cord under the headliner in a few weeks. The rear window dropped so I’ll have Dave at Apex do both, and a rotor/brake job on my other in a few weeks. Just lost my Dad so taking things one day at a time.

 

[EndeavoredH3]

113f today cruising down the 101. I’ll take these temps all day long.

Holly heck....we've been in Black Forest, Germany....absolut relaxing
Hummer in the shed ...he braved the mountain roads and some 30° Celsius without a problem , did almost 830Km

Nope. Not planning a kit. Its not too difficult, though. All off-the-shelf parts and the only real mod is drilling and tapping the output shaft of the t-case. If you are running a spring-over or a bunch of lift, its a great mod.

Re doing the wire loom and upgrading the battery cables to 2 gauge.

I think everybody should redo their wire loom. I solved a lot of errors just by doing that.

Which errors cleared after redo on wire loom?

I had the dreaded Service Stab Sys Traction Failed - Reduced Power message as well as the issue the car shaking like it had lost 2 coils.

 

[H3Hummer]

Well planing so much for my rig... just assembling lots op parts that can use in future....... already have new brakes front and rear with rotors, new front wheel hubs kit with abs cable, new rear bearings, new screws and nuts for all what's about leaf springs, mounts and suspension cause those getting hard to find .... found a couple of front half shafts from AC Delco in Germany ...lucky me so I got 4 now in my garage.....
so the rest of my listing in the CLUTCH post..... will be purchased in time. And lucky only got ACDelco or Doman parts.

 

[H3Hummer]

Found the complete Clutch kit (Sachs ) at Rockauto and had it delivered on Friday planed to replace it second week of December

 

[H3Hummer]

4 New Bilstein shocks on the way to, glad to find them in Germany. Never had problems with those, and for me, the ride was good on Bilsteins. So why changing a winning team and for a descent price

 

[H3Hummer]

So.... to find in future...but search goes on next year

the leaf springs and the complete exhaust

 

[Vaderdad]

I’m currently diagnosing my Stab Sys Off error code and my car is in limp mode. I also have an over due radiator job I must fix. Already did the water pump, thermostat, oil pressure sensor switch, and new touch screen reverse cam.

 

[H3Hummer]

So today, 4 new Bilstein installed and new Bump stops as well. Installed new Bolts on top of the rear shocks ...GM's are nuts .....

I get that we have pretty much exhausted every possible technical discussion after 20 years. This was probably my all time favorite thread on this forum. Surely some of us still have to be out there playing with our full size Tonka trucks, right? We've had a little snow recently. Not a lot, but enough to change the scenery and make the trails a little trickier. Post up your adventures!

 

[H3Hummer]

changed all Diff breathers with much longer.... the rear axle was so short from stock , so now it's 40" higher Prevents from having mayo in the those diffs

 

[cgalpha08]

New power steering pump and reservoir (psc) with some radial dynamics reservoir cap and pressure relief valve.

Also added a 9th rocklight
