What's quicker 0-60 mph - 2hi or 4lo? (video inside)...

That's not exactly true. I didn't turn the steering wheel more than 1/2 turn while on the pavement so I wouldn't bind the driveline. That's really hard on it as you said.
When you're locked in 4lo, you're distributing the torque 50/50 front and rear. Even though you've got more torque available from the transfer case gear reduction, you split it nicely between the front and rear axle so neither axle gets overloaded.
In 2hi all the torque goes to the rear end, so that's just as hard (if not harder) on the rear than launching in 4lo.
The only part that really gets stressed in 4lo is the transfer case itself.
You're more likely to bust something off-roading in 4lo because when you lift wheels you can put 100% of the torque on a single axle.

Of course he wanted to get it replaced under warranty stating that it just stop going one day, but the tell tale sign that told me he lied was the shift on the fly switch on the dash was in 4lo when it came of the tow truck. That was the worse case I have ever seen, and I have seen quite a few. Read your owner's manual about 4lo operation. Like everyone has said, DO NOT USE ON DRY PAVEMENT & DO NOT EXCEED 25 MPH! Failure WILL occur.
