Followed my usual m.o. today.
Reasearched....
Bought parts....
Asked for help....
Reached out to a friend for guidance....
Preped the work area....
Got right tools and stuff....

Sugar went up on wheel ramps. Followed Alrocks tutorial (very messy dropping trans pan).
Was all over under Sugar and was in the final phase of putting trans pan on and tightening...

I'm very bruised and sore but God blessed me and watched over mme, because the Hummer rolled down the ramp and pinned myright leg partialy under drivers wheel and stomache under frame rail. I still can not figure out how it missed me or how it made it over the safety stops. Please be very cautious.

Chris

(p.s. the trans pan still is a bit damp and dripping. Dont see any leaks or places it is dripping from. Brand new filter and gasket from Autozone.)

:'( I can tell you guys Im shook bad)

Wow, glad you are okay, or at least close to it.

On the trans, were the two surfaces clean of any residue, like filter pieces sticking to the pan? Also, the torque specs are very low - 11.8 ft lbs, or 16nm. Overtightening could distort the pan and cause leaks.

I know the feeling, time for tire rotation and I'm using my high lift jack to raise the side up on the sliders. Rear wheel has a block and the E-brake is on and just in case the jack stand is under the rear axle, take off the front tire and we are moving along to the rear wheel and BAM the high lift falls of and cracks me on my left arm and shoulder. Thank god I install the spare on the front tire and the jack stand is holding on the gas tank for the truck doesn't hit the ground. Wife saw it coming and if it wasn't for her my skull would have been split wide open.

Hope you get better and stay safe.

glad to hear you are ok. I quit using ramps years ago. Multiple jackstands with wheelchocks are the only method i trust going under the vehicles.

I've seen jack stands fail and I've seen at least one jack fail. When the jack stands fell my dad had come out from underneath our 26' long motorhome only seconds before.

When the jack fell we were near the beginning of 2N17X. my dad's supercharged 94 4 door hardtop (at the time) broke an original ball joint (light duty) where the geared hub wasn't connected to the upper control arm anymore. Billy (some SoCal H1 owners from ~2006 and earlier will remember him) was underneath the truck when the jack failed. only thing that saved him was putting the tire/wheel underneath the factory rocker protection and stopped the truck from crushing him. Billy is also very wiry, so he was lucky since if he was any bigger he would have been hit by the truck even with the tire/wheel underneath it.

The ball joint broke on this obstacle of 2N17X. My dad went from a 01 Wagon to a 94 and was not aware of having to BTM at the time to get the torsen diffs to engage since the 01 had TT4. Which explains the dust in the picture.

HOLY CRAP is right, glad to hear it was NOT worse. I own a construction company and have a 5000 sf shop. We work on everything from chainsaws to 120,000 excavators and we have had incidences as you might imagine. We use jacks, ramps, blocks, overhead crane, etc...

What we try to practice now is no matter what you lift with, we put the largest piece of wood/timber block under the vehicle you can slide in there. Preferable bigger and thicker then the person you are putting under there. No matter what happens, at least you wont get squished completely.

Thank you everyone of ya!Yea, yesterday was a ruff day...lots of doubting and chit. NO! Lol! I will not be entrusting myself / life to shop ramps alone anymore.Funny thing is I'm a very cautious guy when it comes to stuff like this. GF was even commenting with all my pickyness and safety conscious crap I do... it was her Hummer that damn near did me in. I told her had she not stopped the truck as fast she could of had the house and Happy. Lol! Chris

H3's don't have a "PARK" unless both ends of the vehicle are on the ground and both drivelines are hooked-up. If you park on a slope, and jack-up either end of the truck...it will roll (even in PARK). If you remove the driveshaft...it will roll (even in PARK). Unlike a 2WD vehicle that locks the rear driveshaft to something solid inside the tranny...the full-time 4WD vehicle works by putting the front & rear driveshafts in a bind with each other. As long as both drivelines are intact and the tires on the ground...the truck is bound by friction. But as soon as you sever either end of this connection, there is nothing to hold the truck in place...and away she goes!

Glad your okay.

If you were to shift into 4 low I believe you could disconnect one driveshaft and still it would prevent the vehicle from rolling. I may be wrong but doesn't the engagement in the transfer case lock until you shift back into high?

In the normal 4 the transfer case is an open differential.

Glad to hear you're alright :thumbs:. I have a guy that has a vehicle lift in his garage. I think i'll ask to use it if/when I need to work on anything under it!!
