I am no mechanic, but I know that using the Tundras 4x4 while on pavement is not the best thing to do. Well, I tested it. I had my wife and daughter waiting for me in the pickup, and my little 18mo daughter decided to turn the dial to 4hi. I was pulling a trailer out of a driveway onto a busy street and didn't notice anything funny until I started to turn. My first 2 thoughts were I got to hurry and swing out of the way of oncoming traffic, and why am I not turning? I turned on the pavement for 20-30 feet and got the pickup straight and realized at the same time I had been in 4wd.

My wife says, Oh, I was going to tell you she turned that knob.
Anyway, now I am hearing a slight vibration, it pulsates slightly, and reminds me of the noise or feeling of offroad tires that are out of balance, or worn. It varies with the speed I am driving.
Did I do something to the tires, scraping them as I turned that creates this noise, or could I have ground some gears in 20 feet?
Lastly, I am still under warranty, but would they cover anything like this, especially knowing I drove in 4wd on pavement, even though it was not intentional?
I know, I probably should take it in, but I trust the internet more than the dealer mechanics, sadly.
