Did this last year myself. Also would not trust the jack holes.

While it's all apart, you might want to replace the diff seals, too. I also replaced drive shaft center bearing and bearing mount. Just easy and cheap while you're in there.

And - dunno the miles on your axles - but rebuild of these was the driver of my project. Per advice from guys here, I reversed them on re-fit to put the stresses on the opposite faces for the next 300k miles!
