Well DUH!!!!!!!!..
You can run 4x4hi on dry pavement in conditions that does not involve changing the Constant velocity between any of the front two tires. I.E. Turning. But switching lanes ect.... No that wont hurt, but why would you want to?
Now running 150miles on dry pavement highway speeds? Unless there is reasons of Needing 4x4 I would not recommend it. Due to well higher gas consumption and unnessasry wear [this is not any diffrent then wear on the rear axle].
During crappy winters here in Good Ol North west Indiana. I run my 4x4 for 30miles or so to my destination. do what I need. Then drive back 30 miles in 4x4. How ever I will try to allways go back to 4x2 if I can get reasonable traction.
