Forgot 4hi, did I damage it?

Well, I may have messed up. I had to park off road in a slippery field, so switched to 4hi. When leaving several hours later, I was not paying attention and left it in 4hi. Drove all the way home. 25 miles at 70 mph. No tight corners, so I didn't realize it until I got home and went to pull into the driveway. Making the tight turn I felt it bind and realized what I had done.

Now the question. It seems to shift in and out of 4wd fine. No funny noises, no warning lights. How can I check that everything is still working the way it should? I don't need 4wd often, but when I do I tend to be out in the middle of nowhere or on a very slippery boat ramp. Did I luck out and not tear anything up or am I going to use 4wd at some point and then realize that it isn't right? Surely others have done this, what breaks and is it easy to know if I messed something up??
