Possible damage driving in 4wd on pavement

Hi all, new member here: we all know we’re not supposed to drive in four-wheel-drive on dry pavement, but beyond gear binding and transmission windup I’m wondering what other damages are possible from doing so? I have a 2000 Tundra V8 4x4. I was driving and my wife accidentally hit the 4H button instead of the a/c recirculate. I didn’t notice, and I didn’t notice the 4H light being on. We drove for about 30 miles at 60 mph on a winding highway. I did notice the difference in steering and handling, but thought it was the wind and the uneven road surface. When we finally pulled over, the front axles were smoking! There was heavy smell of burning oil, and/or rubber. We let it cool off, checked the transmission fluid, which was OK, checked it in and out of four-wheel-drive, forward and reverse, everything seemed OK except for the acrid smell. We drove it home about 25 miles and it did fine. It left a thin solid trail of oil down the driveway when I backed it in. I am wondering what kind of damage could have resulted. Did I burn up seals in the front axles (CV joints?)? what should I check? Thanks

 

Check the front axle and transfer case fluid. More than likely it just puked a bunch of fluid out of the vent tube. I've done that when I forget to unlock the hubs on my k5 and hit the highway.

 

Check the front differential breather first? Located on the firewall in the engine compartment. Should be two of them side by side, give them both a good spin and jiggle. Maybe running in 4wd at high speed for a prolonged period got the fluids nice and warm and the breather is plugged causing the expansion to force fluid out of the seals? The front axles are always spinning and always contacting said sealing surfaces so whether you’re in or out of 4wd shouldn’t affect that part. I would change the front diff fluid as well. The bad smell is hopefully just the leaking fluid getting slung onto warm engine parts.
