Could be an electrical problem, but if it was a hard enough impact. I'd more inclined to check all the drivetrain gears, diffs, shafts etc. All it takes is one gear to move slightly & it will lock everything up tight. Try to force it to move before checking it over & that's when you risk making more damage. By all means check anything else but don't check the moving parts at your peril.

By the way if you want to change text or a whole website to a different language - try Babelfish, it really works.
