Broke differential mount going over a big hole now have issues with four wheel drive

Vehicle listed above has a Corvette engine. Not seeing a bad hole I bounce the tar out of the vehicle. This resulted in broke motor mount. Fixed. When I left shop in 4wheel drive came to ridge and discovered rear differential was not working. Backed up in 2wd pulled forward couple times though it sounded like sandpaper rubbing but it engaged. Got to bad sand creek crossing (very ruff ranch) and discovered rear differential was not helping. This busted driver side front locking hub.
When you put in 2wd the drive line moves freely in first or reverse. But you hear sandpaper scraping sound. Could I have gotten the linkage out of adjustment when I lifted motor on one side or was it lucky day and everything broke at once?
I have read responses on others so I understand checking axles. Thanks
