Valid point.

WOW........So have you already broke all of those parts?
My experience has been different. The 8.25 rear flat wore out while the transmission, transfer case, and front diff. were still going well.

The front diff is a 7.25, which is quite weak. Pinion is damn near microscopic. 42/44/46RE are ticking time bombs. (5)45RFE and transfercase aren't bad. 8.25 will take some abuse but eventually the pinion will give up.
