Maybe I should have clarified my post:

The CORRECT way to install axle studs, especially when the opening on my A body axles is .680 and the replacement studs are .720, is with a press. No need to stress-test the studs and pull them through over-tightening the stud with a socket jammed over it. It lasted 10 yrs? Good for you.

And yes, if you pull both axles, it will leak out. Or you can wait until it's dripping and go look for a pan. Or just let it drip while you hammer in the studs....
