assuming you have equal weight side to side, bought everything I have rwd would all tilt to the driver(gas tank)Lifting it in the center is so convenient. One lift, and both jackstands go under.

I still have my 1977 electras, brand new looking. I also have a 75 grand ams and some g bodys... comes down to it I have like 10 of these *******, but only 2 of them are nicer, larger ones which are confidence inspiring. My dad tho has a really cool one that "folds" down and has rubber protection on the contact area, im guessing the bumpers were not notched.You guys are thinking too new here. I still have the original bumper jack for my 76 Trans Am. I don't trust it at all. Reason being, and I'm not afraid to admit this, is that I really don't know how to use the thing. Maybe it's incomplete, maybe it doesn't function correctly, but as to the point of the OP... definitely not using a bumper jack on a rear diff.
Ahhhh @RichLo you beat me to it....

More-or-less directly under the springs...right?Fwiw I've seen loaded semis and concrete trucks lifted using an air powered floor jack on the axle housing, one side at a time.
The F450SD wrecker I drive actually has a factory bottle jack wing-nutted behind the seat. First one I've ever seen without a "jack delete" - literally every brand-new wrecker I've been in did not come with the factory jack.Been dicking with cars (and trucks) for decades.
It never occurred to me until a couple years ago that jacking the middle of the rear axle could cause problems.
Truth is, it can...depending on the vehicle weight. If there's enough weight, the axle housing can be permanently distorted by lifting the whole rear of the vehicle by jacking under the differential area. The axle axle could be bowed down at the ends.
I don't think there's any risk when jacking up a solid-axle RWD car, or a typical pickup. A motor-home, or school-bus may be different. A 2-ton grain truck even without a load could be an issue.
Since I don't work on bigass vehicles, I don't worry about it.
