Enjoying the Snopocolypse 2011 I was trying my truck in the snow.
03 Escalade EXT 108k miles

She did well untill i noticed the back end kick out. Stabilitrac cought me but I thought AWD trucks dont do that.

So I went to a paking lot with some store fronts to see for myself.

No front wheel spin just rear wheel.

Next I took her home and got all 4 wheels off the ground.

No front wheel spin.

I put her in Neutral and spun the front wheels by hand they would spin freely no engaging the other front wheel.

Then I put it in Drie and shut her off.

Front wheels wont spin...

Start her up and put it in Drive and I have front wheel spin.

What am I missing here.
