Do many of you guys jack up the rear of the car by putting a jack under the differential? If so, are you careful to go forward of the diff pan to avoid stress on the pan and seal?

Also, I’m just curious – – are there any issues with stability or balancing by raising the vehicle from such a narrow “sole” point. I’ve just never done it that way.

I hesitate to admit it, but I use 2 low profile hydraulic jacks and walk back-and-forth from each side to raise the rear:
 
If you have a solid-axle car, I don't recommend it, even though the owner's manual says it's OK. (Might be OK for and IRS car; I dunno.) The joint between the axle tube and the differential is not very strong, especially on some units. You can end up with a loose axle tube.

On my rear end (I mean, my car's rear end), one axle tube was loose. I can't be sure that jacking under then diff caused it, but it did illustrate how weak that joint is.
 
Mine is a solid axle. Does a loose axle tube make noise? I finished my rebuild—finally. The car is great. But I am hearing a rattle clank from my right rear. Can’t pinpoint it yet. Though I doubt it, the sound might be part of the passenger door internal hardware, like a loose window regulator, but the sound seems more like the rear fender area and I’m certain it’s not the shock.

I try to not use the axle pumpkin as the drain plug sits right there and the pressure goes on it.
I often use the frame cross tube near the very rear and quickly put the frame stands under the frame on both sides.

I use a single jack plus a 2x4 across the rear frame rails - I think just ahead of the differential (can’t remember exactly), ensuring all the loose bits (brake lines, exhaust, etc) are clear.
