4x4 vs. AWD

What is the difference in setup between these two? Other than the obvious AWD is all-time and 4x4 is optional. Different t-case? or what?

That is what I figured, but is it just like a 4x4 transfer case but locked in all the time or what? Or is it a totally different concept?

The axles are the same... The transfer case kicks in and out differently. My wife's Durango is AWD then can be switched to 4wd HIGH and 4wd LOW. Where as for my truck it is 2wd, 4wd High and 4wd LOW. But the axles are the same model numbers!!

So basically it is all internal in the transfer case. Nothing else really. So what would the difference be between AWD and 4WD high? That is interesting. You would think if it was in AWD what could possibly be any different than 4HI......Other than top speed maybe but not sure that makes any sense. Why would you be able to go 80 in AWD but stay under 60 in 4HI...

AWD is a computer-controlled system that detects which wheels are slipping and provides power to the other wheels to compensate. Under normal driving it puts no or very little power to the front axle, so you are basically driving in 2WD 'til the rears slip, then it automatically engages.

However, every AWD system is different in the torque split f/r.

Is there a way to tell the computer to put power in the wheels like a full time 4wd system rather than act like an AWD system?

I believe the trucks have a 4x4 Lo and Hi option as well. Just not a 2wd like the 4wd trucks if that makes sense....lol.
