Ouch, not a good thing to do. Check out the driving section in your owner's manual and look for the 4x4 section.
What happened to you is normal, and I'm sure it probably felt a little bit like the truck was resisting and jumping a little bit while you were turning.
Check out this link if you have time, it has some pretty good information.
You most likely didn't cause any damage this time, just remember that 4x4 is never meant to be used on dry pavement.
