Where do you jack up a Hummer EV?

The Hummer EV is such a beast that even a 24” floor jack can’t get the tires off the ground to remove, instead the owner had to lift from the LCA as well. Can't we also lift from the axle? Usually that's what I see folks use as another jack point.

Well, yeah, folks will do that, but probably not EV-driving folks. I have found it sometimes hard to "forget" all the informal knowledge I learned about ICE vehicles over my life and retrain my vision and thinking to see EVs are they are. The Hummer EV isn't like a conventional frame-rail, leaf-spring-suspension ICE truck. It has a rear drive unit mounted on an isolated cradle with independent suspension and doesn't have a rear differential/axle assembly with external axle housings you could put a jack onto. Those "axles" you see underneath are the actual drive-shafts, connected to the motor and wheel with CV joints. It is designed to transmit torque, but not carry weight load. The bearings in the wheels + the body structure itself are designed for those loads. Attempt to put some vertical force directly on the drive shaft you'll destroy the shaft and likely damage a lot of other stuff. And "alternative" under-body jacking points not shown in the owner's manual should also be verboten. The Hummer BT1 platform structure is unique. What "common sense" might say is a good jacking point likely really is not.

This is a question that I had asked about a long time ago... If you were to have to Jack this Beast to change a tire, what type of jack is GM providing? Because there is No Way I would trust one of the standard Dinky scissor jacks that normally come with a vehicle. We have seen the alternate optional spares for the SUT but I haven't seen a jack for this truck. I was once denied service at a Goodyear tire store in my work truck (a 1500 Ram) because they said that it was too heavy for their lift (I keep it loaded full with probably more than what it's rated for but seriously they wouldn't even put it on their lift).
