Hey, I just got a 97 tahoe and it didn't come with the manual and I was just wondering if there are any certain ways to operate 4x4, I stopped and switched to 4hi on pavement (I know it's bad but it wasn't for a long time, I just drove up a curb lol) and when I turn really sharp it acts like I have a flat. What's up with that? And does driving alittle on dry pavement in 4x4 hurt?
