2010 Suburban AWD or 4WD, Confusion ?

[kirkdc]

Currently interested in buying a 2010 Suburban but questioning the 4 WD set up in this one. See posted pic, this is what the dash looks like showing 2 hi - auto - and 4 hi. I've seen others with a selector knob showing 2hi - auto- 4hi and 4 lo.

Whats the difference? I know in the pic there is no 4 low selection, that's apparent - but when it's in 4hi mode is it TRUE 4 WD? Or some type of limited slip/AWD set up which IMO is not a better set up for ice and snow. I've googled the heck out of this topic and come up empty. I live up in the CO Rockies where I need a solid 4x4 system and don't want any rinky d ink AWD/hybrid set ups that don't fully engage all 4 and/or work on a limited slip some basis of sorts. I am almost assuming that this vehicle has possibly some rinky-din k 4x4...or maybe I'm totally wrong and that when its in 4hi the front and rear is always engaged. And the only difference is that it has no 4 low. Any help is super-appreciated.

In viewing other surburbans/yukons for sale I've seen this type of selector knob for the 4x4. This is why I'm stumped. It's def' got to be a different 4x4 set up.

That simply a single speed transfer case. It is true 4WD. You just don’t get the 4 LO option.

Oh wow that's a relief as I really like the rig. Are you 100% sure? just checking...my apologies.

One is a single speed transfer case
One is a 2-speed transfer case
Auto- is 4wheel drive on demand when wheels slip is detected
Only the Yukon Denali/escalades generally have AWD
In all cases the front is a open diff
Most have the G80 rear end which is a automatic locker at speed, I believe around 15mph is when it locks if a wheel slips

Ok, that helps and that's where I was getting confused....seeing Denali's, Escalades with AWD lisitngs. Plus I never knew there was a single speed t case that had no 4 low. I'm a 66 year old geezer and would be happy with a 4x4 manual shift lever and 2 hi, 4 low and high and a neutral.

Speaking of Neutral. Does this 2010 Suburban have an application to be the t-case in neutral?

It's in neutral when shifted to neutral, are you asking about this for when it would be towed? I believe that requires the driveshaft to be disconnected
